Hello, I am trying to fabricate a P3HT:PCBM based organic solar cell. I do not have thermal evaporation equipment available. Can anyone please suggest me some other vacuum free technique to deposit the top metal electrode?
Hi, Brishty,
Silver paste may be a good solution.
Alternatively silver nanoparticles could do a job too. They are widely used for solution-processed organic electronic devices.
Hope it helps

Welcome,
You can try metal pastes that can be printed as a thick film layer.
Best wishes
Apart from above valuable suggestions, you can use AgNWs solution to form a AgNWs electrode network. It will facilitates the transparent layer, incase if you are using the electrode side as window layer for light illumination.

Thank you. I am going through literature according to your suggestion.
Another idea -- printed carbon nano-tubes. Also, did you try mercury probe contact?
Hi, You can use the Fields metal (FM), an eutectic alloy (Bi/In/Sn: 32.5%, 51%, and 16.5%, respectively) with a melting point above 62◦C, that is easily deposited by drop casting under vacuum-free process and at air atmosphere, the detailed process can be seen in the next document:Article Small Molecules Derived from Thieno[3,4-c]pyrrole-4,6-dione ...
