After depositing the back contact on my perovskite cell, do I need to anneal the cell again?

I fabricated my perovskite using PEDOT:PSS/MAPbI3/PCBM/Al. After depositing the back contact (Al), I annealed the cell again at 100 degrees for another 10 minutes. I obtained no PCE. I would like...

What is the reason for the non-monotonic variation of roughness for sputtered Cu films annealed at 100, 200 and 300 degree Celsius?

I have prepared Copper thin films by magnetron sputtering and the samples have been annealed at 100, 200 and 300 degree celsius. The variation of the rms roughness and all other AFM height related...
