Electrode pastes

Screen-printing is an automated and reproducible way to prepare electrodes for e.g. dye-sensitized and perovskite solar cells. Dyenamo offers screen-printable pastes developed for realizing efficient TiO2 working electrodes and Pt counter electrodes. The pastes can e.g. be applied with the laboratory screen-printer DN-HM02.

DN-CP01

Carbon paste


Description:
A carbon paste providing a great connection to perovskite layers removing need for an intermediate hole conductor layer and opening up for novel process methods and concepts for perovskite solar cells and modules.

Properties:
  • Curing temperature:120 °C
  • Curing time: 15 minutes
  • Deposition method:Doctor-blading is recommended but it is also suitable for other
  • methods including screen-printing

Counter electrode pastes

DN-EP01

Pt paste


Description:
DN-EP01 is a thixotropic terpineol-based screen-printable Pt paste with a viscosity of 4-7 Pa.s at 10s-1. The printed layer is conventionally sintered around 450 °C, resulting in a layer of uniformly distributed Pt nano-particles with good transparency and high catalytic activity. It can equally be applied by the so-called doctor blading technique. The paste color is straw or light yellow.

Screen-printable TiO2 pastes

DN-EP02

Blocking layer TiO2 paste


Description:
DN-EP02 is a terpineol-based screen-printable paste opening for a thin and dense blocking layer of TiO2. Such an under-layer is deposited below the conventional nanocrystalline TiO2 layer in order to reduce the contact between the active materials, such as hole transport material, perovskite material, and DSSC electrolytes, to the conductive substrate. The paste viscosity is 15-25 Pa.s at10s-1. The printed layer is conventionally sintered around 450 - 550 °C.

DN-EP03

Screen-printable transparent TiO2 paste, 18 - 20 nm


Description:
DN-EP03 is a screen-printable TiO2 paste for preparing working electrodes for e.g. perovskite and dye-sensitized solar cells. The paste is characterized by a high level of particle dispersion. This is beneficial for DSSC as the layers can be transparent up towards a thickness of 10 µm, but also for perovskite solar cells due to the layer uniformity. The layers can be sintered throughout a temperature range of 450 to 550 °C to obtain a mesoscopic layer.

Properties:
  • Anatase particle size:18 - 20 nm
  • Concentration:appr. 20 wt. (can be diluted with terpineol to make thinner                                                           layers)
  • Medium:Terpineol, ester alcohols, polymeric binders
  • Specific surface area:approx. 85 m2/g

DN-GPS-22OS

Screen-printable opaque TiO2 paste, 22 - 25 nm


Description:
Paste with slightly larger TiO2 particles in relation to DN-GPS-18OS including light-scattering particles for obtaining combined active TiO2 particles and light-scattering particles in one single layer.

Properties:
  • Anatase particle size:22 - 25 nm
  • Scatter particle size:> 150 nm
  • Concentration:appr. 16 wt.
  • Medium:Terpineol, polymeric binders
  • Specific surface area:50 - 60 m2/g
