Dyenamo launches two new ligands for metal complexation
The product line Building blocks aims at offering our customers a shortcut to rapid and cost-efficient assembly of advanced molecules of their own design. Due to popular demand, we now broaden this product line with the two ligands bpyPY4 (DN-BB05) and tmby (DN-BB06). Both are versatile multidentate ligands that can be used together with many different metal ions. Examples from litterature include the use of Co(II)/(III) bpyPY4 complexes for improved device stability (DOI: 10.1002/anie.201300070) and the use of Cu(I)/(II) tmby complexes as redox couples in DSSCs (DOI: 10.1021/jacs.6b10721).
Dyenamo intensifies the collaboration with Elixir Technologies
Dyenamo is happy to announce that we have taken the next step in our successful collaboration with Elixir Technologies. From November 2017, Dyenamo is exclusive distributor for Elixir's manufacturing equipment for dye-sensitized and perovskite solar cells outside India. Consequently, we can now offer a broad set of standard products, such as equipment for device encapsulation, screen printing, electrode sintering, spin coating, glass cutting, hole drilling and spray pyrolysis. We also offer custom-made solutions for process steps such as dye application, electrolyte filling, pick and place positioning equipment and dispensing solutions for e.g. adhesives or current collectors.
Dyenamo launches high-performance TiO2 paste
We are happy to introduce the screen-printable TiO2 paste DN-EP03. It is available in any amounts and especially suitable for opaque DSSC (in combination with a scattering layer) and Co- or Cu-based electrolytes, semi-transparent DSSC (transparent layer up towards 10 µm thickness), low-power DSSC and perovskite solar cells (homogenous layers < 500 nm).
We are also pleased to announce that we offer three water-based TiO2 pastes as temporary offers.
DSSC strikes back - a great experience and success!
The Dyenamo conference "DSSC strikes back" gathered 115 participants from 18 nations in Uppsala, Sweden 16-17 October. The two days were very intense with 31 oral presentations and 32 posters. It is obviously not appropriate to review your own arrangement. Nevertheless, we dare announcing that the conference was a great success. This was confirmed by the endorsements we have received during and after the conference. Here are a few examples of such written comments:
"DSSC strikes back was a milestone in my professional life"
"This was one of the most memorable business trips in my life."
"I would like to congratulate all of you to the very successful conference: It was really very impressive!"
"I would like to thank you again for the well organized and beneficial conference. It was a lot of fun and informative, and as discussed, we are waiting for version number 2."
"Thank you very much for the wonderful DSSC conference you have organized. Especially I appreciate a perfect mix of talks from academic groups and companies."
"Congratulations again for a great conference!"
"Congratulations for the conference, the Dyenamo team truly did a great job with the organization."
"This was the right initiative at the right time by the right people."
We want to thank all the participants for creating such a nice event. Below please find some memories from the event (photo Louise Seregard).

We are pleased to announce that Sonja Prideaux has joined Dyenamo. Sonja is well-known to the Dyenamo team, as she was helping us out in parallel to her studies in chemical engineering at KTH in Stockholm. After completing her studies in the summer of 2017, she immediately joined Dyenamo. Many of you know her as conference coordinator for "DSSC strikes back". However, this was a temporary sidetrack from her engagement as Production Scientist and Sales Representative at Dyenamo.
We are also pleased to announce that Dr. Qian Gao has been appointed Sales Manager of China.
Dyenamo launches new hole transport material: X55 (DN-X07)
We now launch our latest high-performance hole conductor DN-X07, also known as X55. This spiro[fluorene-9,9'-xanthene] (SFX) based material has been used to obtain perovskite solar cell device efficiencies of up to 20.8% by KTH, Stockholm in collaboration with EPFL, Switzerland (DOI: 10.1016/j.chempr.2017.03.011). For more information, please visit the product description.
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.
Low-power DSSC device with 28.9 % conversion efficiency at 1000 Lux using Dyenamo chemistry
Researchers at EPFL have obtained highly impressive power output values at indoor low-light levels indicating that Cu-based DSSC is the best performing indoor light harvesting system of all PV technologies (Freitag et al., Nature Photonics | DOI: 10.1038/nphoton.2017.60). This opens for a massive market related to IoT (Internet of Things) applications. Dyenamo is happy to have contributed to this pioneering work. The key dyes and electrolyte redox mediators are available among our standard dyes and Cu-materials.
Dyenamo product drastically improves cell efficiency
In research led by Gerrit Boschloo it was found that addition of the small electron donor DN-X04 (TPAA) to a standard cobalt-based electrolyte can lead to a large improvement of the performance of dye-sensitized solar cells. This work was recently published in Nature Communications (Nature Commun. 7 (2016) 13934 | DOI: 10.1038/ncomms13934 ).
Dyenamo signs mutual distribution agreement with Everlight
We are happy to annouce that Dyenamo and Everlight Chemical have signed mutual distributors agreements. This means that Dyenamo will be European distributor for Everlight's DSSC chemicals, including the hole-conductor Eversolar® Spiro-OMeTAD, and that Everlight will be Asian distributor (India excluded) for Dyenamo DSSC-materials. This will open new market channels and broaden the selection of DSSC products for both companies.

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.
Dyenamo agreement with Elixir Technologies for Indian market

Record-efficiency for Cu-based DSSC
Dyenamo has in collaboration with the Royal Institute of Technology (KTH) developed a new Cu-based redox-couple, which has been used to obtain cell efficiencies up to 10 % (DOI: 10.1039/C6TA06782D). A key development is that the new complex features an innovative bis(2-pyridyl)ethane ligand in place of the nearly ubiquitous dimethylphenanthroline (dmp) ligand. These materials are now available in our product line for Cu-complexes.

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.
