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-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.
