How efficient are perovskite-silicon tandem solar cells?

Perovskite-silicon tandem cells have reached efficiencies of almost 34%. While perovskite solar cells have become highly efficient in a very short time, perovskite PV is not yet manufactured at scale and a number of challenges must be addressed before perovskites can become a competitive commercial PV technology.

How does a perovskite film change color?

When exposed to ambient conditions, the perovskite film often changes from a dark brown colour to a light-yellow tint. The crystal structure affects the perovskite film's optoelectronic characteristics. Phase transformation in perovskite causes the crystal structure to be distorted, which lowers the efficiency of the cell.
