What types of mask designs for metal deposition, to be used in a PVD system, are best suited for perovskite-based solar cells?
Hello Douglas Monteiro
Build a mask is no easy step, so it depends on your conditions to build them. If you have some laboratory with expertise to do it, you can check the papers and basically replicate any one you want. If you don't have access to expertise in build these masks, so alternatives must be considered.
Feel free to reply if you need more help with this topic. I also work with Perovskites solar cells, and this issue about the masks also is challenging to me.
Best regards,

It mostly depends on the characterisation techniques that follow after making the device. It is advisable to see the shortcomings you face while performing IV, EQE, etc., and design a mask that satisfies your needs. There are basic images available in papers. Follow any of them and modify them after finding the challenges you find using them.
Sputtering or evaporation method is the optimal choice for this method. If your laboratory has such equipment, it is very suitable for this research direction. Wish you have a good research direction.
