A carbon paste for perovskite solar cell to produce high conductivity electrode structures. Dycotec DM-CAP-4703S is a thermoplastic carbon paste for screen printing and blade coating. The paste allows fast drying at low temperature (<100˚C) with a sheet resistance of <10 Ω/sqr/25µm. Proprietary additives are incorporated into the paste to increase work function to enable improved charge transfer from perovskite layers (~35 meV increase compared to undoped carbon paste, DM-CAP-4701S). The paste offers a low cost and stable alternative to gold sputtering.

Product Description

A carbon paste for perovskite solar cell to produce high conductivity electrode structures. Dycotec DM-CAP-4703S is a thermoplastic carbon paste for screen printing and blade coating. The paste allows fast drying at low temperature (<100˚C) with a sheet resistance of <10 Ω/sqr/25µm. Proprietary additives are incorporated into the paste to increase work function to enable improved charge transfer from perovskite layers (~35 meV increase compared to undoped carbon paste, DM-CAP-4701S). The paste offers a low cost and stable alternative to gold sputtering.

Product Benefits

• Compatible with Perovskite solar cells, enabling excellent power conversion efficiency
• Modified work function to enable improved charge transfer (~35 meV increase with respect to undoped DM-CAP-4701S)
• Compatible with flexible perovskite solar cells
• Low temperature (<100 deg. C) and rapid drying (<20 mins)
• Excellent long term durability performance

Paste Preparation

Gently stir before use. Avoid rapid stirring to prevent air entrapment during the stirring process. Once the paste has been removed from the container for printing, this may introduce contamination. Please do not replace the paste in the original container and keep the lids tightly sealed with the inner cap replaced after paste transfer to minimise solvent evaporation. The paste dries rapidly, so screen residence times are limited to <2 hours.
