How to prevent atomic layer deposition (ALD) on some part of substrate area?

05 July 2024 1 2K Report

I do not want to deposit ALD-metal oxides on the metal-electrode portion of a lab-scale organic/perovskite solar cell. Like suggest few easily available hindering agents that can cover that selective area during deposition and can be removed, leaving the metal electrode without deposition.

Hello Saurabh Gupta

You can use a special type of adhesive tape. It's usually known as "kapton tape". I use it to cover my perovskite cell layers, and then I can specify where the layers will be deposited.

Plese let me know if you have any doubts about how to do it.

Best regards,

Ricardo Tadeu
