Hello,
the layout i use for making perovskite solar cells requires a lot of contact cleaning (5x5cm substrate).
So far i used cotton swaps with DMF first and then cotton swaps with ACN.
Problem is that the DMF of course easily attacks the active layer the should remain on the substrate. But with only ACN it is really diff and takes a long time to remove the perovskite.
is there a better way to do it?
Hello!
Although cleaning the contacts with solvent is quick and easy, exposing the layers to these solvents can damage them. You can remove the layers scratching them with a sharp tip or to use a razer blade in order to clean your contacts and avoiding unnecessary device exposure to solvents.
Hope you find this helpful
Hello,
thanks a lot for the answer. As i am working in a glovebox i am a bit worried, that scratching would create to many particles which will remain in the glovebox atmosphere.
