LAPERITIVO - a European consortium for perovskite modules

LAPERITIVO is a novel Horizon Europe project focusing on the development of large-area stable perovskite solar modules, using processes with high manufacturability. Efficiency targets are 22% and 20% for 900 cm² opaque and semi-transparent (with >95% bifaciality) modules, respectively. Key research activities include the deposition of high-quality perovskite films as well as contacting layers over large substrate area using industrially viable techniques. Indoor and outdoor field tests, in line with International Electrotechnical Commission (IEC) standards, will be performed to monitor module reliability. Safety, circularity, and sustainability will be assessed to demonstrate products with minimized environmental impact. The developed semi-transparent modules will be applied to perovskite/silicon four-terminal tandem modules and also to agrivoltaics. Moreover, the design of a perovskite PV pilot line of 200 MW and production capacity of 5 GW in Europe will also be explored.

The project is coordinated by IMEC. Dyenamo's role is development and supply of perovskite-chemistry. Apart from IMEC and Dyenamo, the consortium consists of Universita degli Studi di Roma Tor Vergata, Hellenic Mediterranean University, EMPA, Fraunhofer ISE, IPVF, Électricité de France, CNRS, Becquerel Institute, Pilkington, Voltec Solar, TSE Troller, BeDimansional, SmartGreenScan, CSEM, Engie Laborelec, Singulus Technologies and TotalEnergies.

Highlights from Dyenamo's fourth thematic online workshop 3 June 2020

Our fourth online workshop with the theme "Hole conductors for perovskite solar cells" gathered appr. 90 registered participants from 17 countries. After an opening by Dyenamo's CEO Henrik Pettersson and a technical introduction to the theme by Dyenamo's HTM-expert Bo Xu, the five speakers presented.

Henk Bolink, University of Valencia, discussed vacuum-deposited, doped and undoped, hole transport materials for the p-i-n and the n-i-p structures, respectively. He highlighted that smooth perovskite films open for thin HTM layers (<50 nm). Starting from their early work, he took us to the recent results with efficiencies up to 21.7 % using the HTM TaTM (DN-X11) and the dopant F6-TCNNQ (DN-P20).

Artiom Magomedov from Kaunas University of Technology presented results on their development of monolayer hole-selective contacts for efficient perovskite solar cells. This approach leads to reduced material consumption while ensuring very high efficiency of 20.9 % in p-i-n devices, and 29.2 % in Si/perovskite tandem solar cells using the HTM monolayer called 2PACz (DN-X09).

Samrana Kazim BCMaterials-Basque center for materials, applications & nanostructures, in Spain presented methodology and results from their studies of molecular designing of hole-selective layers, divided into triaxtruxene-based HTMs, cyclopentadithiophene-based HTMs, Zn-pthalocyanine dopants and a novel hydrophobic p-type dopant, respectively.

Jangwon Seo from Korea Research Institute of Chemical Technology (KRICT) emphasized the role of dopants and presented results showing that Li-complexes should be avoided due to the fact that Li⁺ ions easily migrate into the perovskite and deteriorate the device performance. To address this issue, he proposed sodium bis(trifluoromethanesulfonyl)imide (Na-TFSI), that has improved both the efficiency and the stability of perovskite solar cells.

Esmaeil Sheibani from the University of Isfahan discussed the impact of three-dimensional, planar and linking topology of hole transporting material. He presented a new class of asymmetric structures and discussed the fundamental understanding of the influence of sulfur and oxygen group substitutions. Champion efficiencies above 18 % were obtained.

Collectively, the speakers demonstrated the fast development of the perovskite field in general, and hole conductors in particular. Once again, the arrangement worked very efficiently thanks to the motivated participants, excellent talks, interesting questions/discussions and a professional moderator. Many thanks to everyone involved!

The fifth thematic workshop is a status report of the EU-funded project Espresso, which will take place on the 16 June 2020. Thereafter, we take a break to evaluate the events.

Highlights from Dyenamo's third thematic online workshop 20 May 2020

Our third online workshop with the theme "Dye-sensitized solar fuels" gathered appr. 60 registered participants from 12 countries, and five speakers. Here are a few highlights:

Licheng Sun, who recently has taken on a new position at Westlake University in Hangzhou in parallel to his activities at KTH in Stockholm, gave an introduction to the topic. Thereafter, he presented results from visible light driven water splitting based on Ru-dyes-sensitized TiO2 based photoanodes, and discussed key factors influencing the cell performance emphasizing the importance of how strong the catalyst is anchored to the electrode surface.

Murielle Chavarot-Kerlidou from the SolHyCat team at Université Grenoble Alpes/CNRS/CEA Grenoble presented their strategy for and results on functional H₂-evolving dye-sensitized NiO photocathodes relying either on covalent dye-catalyst assemblies or on the co-immobilization of the molecular dye and catalyst components.

Elizabeth Gibson presented highlights from recent work on Dye-sensitized photocathodes for photoelectrochemical devices to generate H2 at Newcastle University. She focused on kinetics measurements and interpretations from systematic variations of dye molecules and catalysts immobilized mainly on NiO photocathodes.

Haining Tian discussed the strategies used at Uppsala University in order to improve the performance of Dye-sensitized Photocathodes by focusing on the current production of the photocathode. He emphasized that the molecular dye design and the device engineering are key parameters to address these factors.

Julien Warnan from the Technical University of Munich presented results and experiences from their recent efforts to demonstrate a water-based colloidal dye-sensitized solar fuel approach. He presented the design and properties of various dyes, including enzyme systems, in order to achieve unassisted solar-driven water-splitting into H₂ and O₂.

Collectively, the speakers demonstrated a field in fast development with interesting scientific challenges and a promising future. Once again, the arrangement worked very efficiently thanks to the motivated participants and excellent talks sharing results and pointing out future development routes. Many thanks to everyone involved!

Encouraged by this and previous workshops, we have already announced the fourth and fifth ones in the series with the topics hole conductors and a status report of the EU-funded project Espresso, respectively.

Highlights from Dyenamo's second thematic online workshop 22 April 2020

Our second online workshop with the theme "Dye-sensitized solar cells using Cu-based redox mediators" gathered appr. 75 registered participants from 15 countries. Once again, we were astonished by the great response to the initiative. After a technical introduction to the topic by Dyenamo, four presentations were given. Here are a few highlights:

Marina Freitag, who recently has moved from Uppsala to Newcastle University, gave an overview of the field and presented her work on liquid and solid-state Cu-based DSS devices. By combining the two sensitizers, coded XY1 (DN-F16) L1 (DN-F02), with the copper complex Cu(II/I)(tmby) (DN-Cu09 and DN-Cu10) as a redox shuttle, record-values were obtained at low-light conditions; open-circuit photovoltage of 1.1 V and power outputs of 18 and 103 µW/cm² at 200 and 1,000 lux, respectively, corresponding to a device efficiency of 34.0%.

Suraj Soman from CSIR-NIIST in India presented a direct comparison between DSSCs using copper and conventional electrolytes (cobalt and iodine) revealing the higher photoconversion efficiencies for the copper-based ones. His talk moreover gave an exciting overview of his activities, ranging from fundamental work to module and pilot-line developments, emphasizing that the ideality factor is higher for Cu-complexes than for the other redox mediators. This requires further studies, in particular the interaction between Cu-complexes and TiO2 surface states. The equipment for module fabrication was developed and installed in Dr. Soman's lab by Dyenamo's partner Elixir Technologies.

Yuhang Liu presented results from EPFL, emphasizing the importance of the photo-absorbing dye and the possibility to further improve the devices by dye modifications. Cu-based DSSCs produce high photovoltage due to their low-lying highest occupied molecular orbital (HOMO) level. Record photovoltages above 1.15V was obtained. Design rules to keep the HOMO level fixed but lowering the LUMO level to redshift the absorption spectrum were presented. Dr. Liu also discussed the development of dyes, WS-70 and WS-72 (DN-F18), for Cu-complex based solid-state DSSCs (zombie-cells) giving record solid-state efficiencies of 11.7%.

Ghufran Hashmi, who presently is in transfer from Aalto to Oulu University in Finland, focused on the counter electrode of Cu-based DSSC devices. He presented promising results with carbon counter electrodes. To measure charge transfer resistances of counter electrodes he presented impedance spectroscopy measurements and the equivalent circuits used. He encouraged the use of sandwich cells assembled by two counter electrodes for such measurements. Moreover, he highlighted the possibility to selectively apply the dye and electrolyte solution with inkjet printing.

We want to thank all the speakers and participants for excellent talks sharing results and pointing out future development routes. We also want to express our gratitude for all the endorsements and positive feedback that we have received for the arrangement. The planning of the third workshop is in progress, more information will be available on our web within shortly.

Highlights from Dyenamo's first thematic online workshop 8 April 2020

Our first online workshop with the theme "Perovskite solar cells using carbon paste DN-CP01" included four presentations and gathered appr. 40 participants from nine countries. We were astonished by the response considering the fact that it was arranged with such short notice. Here are a few highlights from the presentations:

Konrad Wojciechowski reported on Saule's work on using the carbon paste for the p-i-n device structure. The results were impressive with flexible device efficiencies >15 % (1 cm²) with excellent operational (maximum power point) and thermal (85 °C) stability of the devices over 1000 hours of aging.

Bowen Yang from EPFL presented n-i-p device efficiencies around 13 % with good stability under dark condition using DN-CP01. Moreover, she highlighted the necessity and challenge involved in identifying suitable interlayers between perovskite and carbon in order to further improve the device performance.

Lukas Wagner from Fraunhofer ISE, presented initial results from their work on low-temperature perovskite cells using DN-CP01. High photovoltages above 1V and device efficiencies around 12 %, limited by low fill-factor, were presented for the n-i-p structure.

Gerrit Boschloo, Uppsala University, highlighted the importance of introducing a hole-selective layer between the perovskite and the carbon in n-i-p devices. The device efficiencies increased from 12 % to almost 15 % by such measures.

We want to thank all the speakers and participants for excellent talks sharing technical details, successes and obstacles, and for strong engagement and vivid discussion.

Dyenamo materials in DSSC efficiency-record publication, 34 % at 1000 lux from fluorescent light

We congratulate dye-sensitized solar cell researchers at Uppsala University (Michaels et al., DOI: 10.1039/c9sc06145b) for obtaining a conversion efficiency of 34 % at 1000 lux from fluorescent illumination. Moreover, we proudly conclude that the organic dyes XY1 (DN-F16) and L1 (DN-F02) from Dyenamo were key parameters in their work. By combining co-sensitization of these two dyes with an electrolyte based on the Cu-based redox couples DN-Cu09 and DN-Cu10, they managed to maintain a high cell-voltage at low-light conditions. This work is yet another confirmation that our efforts in providing state-of-the-art materials for chemistry-based solar cells contribute to advances in DSSC devices.

Dyenamo launches new reference dye for p-type dye-sensitized solar cells

For many years, the dye DN-FP01 (P1) has served as reference dye for p-type dye solar cells. We are now pleased to launch the dye DN-FP02 (PB6), a p-type dye utilizing a triphenylamine as electron donor, perylene monoimide as electon acceptor and thiophene unit as linker. In contrast to the P1 dye, the oxidation and reduction absorption of this dye can be well separated. In addition, excellent electrical and optical properties and proven stability at elevated temperatures make the dye an obvious candidate for becoming the new reference dye for p-type DSSC.

Dyenamo launches start-up kits for manufacturing perovskite solar cells and low-power DSSC

Research on perovskite solar cells and industrialization of dye-sensitized solar cells for low-power applications are booming. There is a massive interest to enter both fields. However, it is well-known that such chemistry-based solar cell technologies are difficult in practice and that it takes a lot of experience to obtain reproducible well-performing devices. In addition, several expensive pieces of equipment, such as the glovebox for perovskite devices, may create an entrance hurdle to the field for many laboratories. In our continuous ambition to pave the way for researchers and companies, Dyenamo has developed economic start-up kits for perovskite and low-power dye sensitized solar cells, respectively. These kits include all necessary pieces of equipment and materials and a thorough manual for device fabrication. For more details, click here.

The second Dyenamo DSSC conference - confirmation of a new phase for dye-sensitized solar cells

Two years after the memorable "DSSC strikes back" conference, Dyenamo re-gathered students, scientists, companies and engineers from around the world to meet, exchange ideas and their latest DSSC findings. Collectively, the 106 participants from 20 countries made a firm statement that DSSC has entered a new phase where efficiency-records are broken for all device types (opaque, "zombie", see-through, solid-state etc. at both indoor and solar radiation) and that the dream-target of 15 % at full sun now is within reach, and that technology commercialisation is rapidly advancing for IoT and consumer electronics applications (e.g. various sensors, electronic curtains, headphones, solar tables) confirmed by the involvement of high-tech investors (e.g. Softbank) and end-users (e.g. JBL).

We are grateful and humble for all the endorsement for the arrangement. Positive and engaged participants made it very easy to organize things. Thank you to everyone involved! Below please find some memories from the event (photo Louise Seregard).

Dyenamo introduces three new products

Despite the seemingly never ending heat wave in Sweden, we have been working hard to expand our product range.

• F4TCNQ: Molecular p-type dopant. Recently demonstrated to work as a dopant for perovskite (MAPI), enabling the fabrication of highly efficient HTL-free perovskite solar cells.
• High-sensitivity irradiance measurement kit: Designed to solve the challenge of determining power conversion efficiencies (PCE) under artificial lighting conditions, this kit allows you to conveniently determine the radiant flux (Pin in PCE calculation) that your device is exposed to. Thanks to its high sensitivity it can be used even under low light conditions (<100 lux).
• Guanidinium iodide: Expanding our range of high-quality perovskite precursors, we’re now also producing guanidinium iodide. A particularly interesting application for this material are the MA_1–xGua_xPbI₃ perovskites which have been demonstrated to show considerably improved stability.

Dyenamo launches new organic dye: WS-72 (DN-F18)

WS-72 is a dye that addresses a long-standing limitation of metal-free sensitizers for DSSCs: large electron injection voltage loss. Additionally, it efficiently suppresses interfacial recombination, which makes it highly compatible with both Co- and Cu-based redox mediators and thereby enabling high cell voltages (up to 1.1 V) and excellent performance. Together with Cu(tmby)2 solid-state device efficiencies of up to 11.7% under AM1.5G conditions have been demonstrated.

New efficiency records for Cu-based DSSC using Dyenamo chemistry

Researchers at EPFL have followed up their breakthrough paper on Cu-based DSSC technologies (Freitag et al., Nature Photonics | DOI: 10.1038/nphoton.2017.60) resulting in efficiencies >13 % at 1000 W/m² and power conversion efficiency of 32% under 1000 Lux artificial indoor light (Cao et al., Joule (2018), DOI: 10.1016/j.joule.2018.03.017). The results are important as they confirm that Cu-based DSSC is the best performing indoor light harvesting system of all PV technologies, and demonstrate the potential of the Cu-chemistry for outdoor applications. The key dyes and electrolyte redox mediators are available among our standard dyes and Cu-materials.

Dyenamo launches low-temperature carbon paste for hole-conductor-free perovskite solar cells

After intense work, we are pleased to announce the new carbon paste DN-CP01. This paste can be applied directly on the perovskite layer and cured at around 100 °C. As the carbon paste makes a great connection to the perovskite layer, there is no need for an intermediate hole conductor layer. Consequently, it opens up for novel process methods and concepts for perovskite solar cells and modules. This includes flexible substrates since the cured carbon layers can be bent. The functionality has been verified by our partner KTH (Royal Institute of Technology in Stockholm) that has reached 15% perovskite solar cell efficiency with the carbon paste without using an intermediate hole conductor (publication in progress). The carbon paste is primarily applied by doctor-blading but it is also suitable for screen-printing.

Great response to Dyenamo DSSC conference in Uppsala 16-17 October 2017

Organizing a DSSC conference was not an obvious decision for Dyenamo. It was triggered by the fact that we sensed an upcoming DSSC trend in combination with the lack of an active forum to meet. We can now conclude that this was a correct analysis and we are pleasantly surprised by the fact that we have received >60 abstracts. We could thus easily have organized a longer conference.

We are pleased to announce three additional keynote speakers; Md. K. Nazeeruddin from EPFL, Peng Wang from Zhejiang University and Kyusoon Shin from Dongjin Semichem.

As a result of the high numbers of abstracts, there was a sharp cut for oral presentations. However, it also means that there will be an excellent poster session. The oral and poster contributions have been selected and the responsible people have been informed. The program will be presented on this website within shortly. Please remember to register before 15 August as the fee thereafter will be increased.

We are also very pleased to see that the registrations for the Dyenamo training and coaching day are coming in.

PTAA for perovskite cells

In last week's Science paper (DOI: 10.1126/science.aah5557), EPFL in Switzerland has shown that PTAA (Poly[bis(4-phenyl)(2,4,6-trimethylphenyl)amine]) plays an important part in making highly stable perovskite solar cells by preventing metal atoms from the electrode from diffusing into the perovskite. Polymer-coated cells maintained 95% of their initial performance at 85°C for 500 hours under full solar illumination and maximum power point tracking. Dyenamo's long-chained PTAA molecular weight (22000 g/mol) is optimized for the high conductivity required in perovskite solar cells.

The material has been used to obtain solar cell efficiencies around 20 % (DOI: 10.1039/C6EE00056H), i.e. this is a hole-conductor material that is competitive to Spiro-OMeTAD in device performance. Dyenamo sells the material in three batch sizes; 100 g for 61 900 SEK, 10 g for 9 900 SEK and 1 g for 1 900 SEK, all prices excluding VAT and transport. Larger batches can be obtained on demand. More information at Hole Transport Materials.

Dyenamo yellow improves perovskite solar cells

Doctorbladed perovskite solar cells on conducting polymer substrate showed a marked increase in performance, when a small organic dye molecule was added to the polymer solution (Y. Deng et al., Energy Environ. Sci., 2015, 8, 1544). The molecule in question is
(z)-2-cyano-3-(4-(diphenylamino)phenyl)acrylic acid), also known as L0 or Dyenamo yellow (DN-F01). The effect was attributed to the improved wetting of the perovskite solution on the polymer layer: Dyenamo yellow makes the polymer layer more polar.
