Have researchers begun trying different metals in perovskite solar cells? I've seen tin and lead published, but what about copper, zinc, magnesium, calcium, or any other +2 metal?
Dear Brandon
I am not working directly on Perovskites, but read published materials. As you already know, Pb & Sn are used.
A good Chemist will suggest right elements for this material. The first criteria is the size of the atom so that it does not produce defective crystal lattice. Similar size will produce an un-disturbed lattice. Many other electrical and optical properties of the elements will interfere. Researchers need to carefully try and check different elements.
This is a very basic answer I can give. It is better to consider toxic nature and availability before trying the new research.

Thank you everyone. I suppose I should have been more specific. I know of the inorganic varieties of perovskites but I am interested in the ones used for solar cells which are commonly of the organometal halide variety.
