Perovskite solar cells have shown remarkable progress in recent years with rapid increases in efficiency, from reports of about 3% in 2009 to over 25% today. While perovskite solar cells have become highly efficient in a very short time, a number of challenges remain before they can become a competitive commercial technology. Research Directions
In sensitized solar cells, in contrast, it was very easy to replace one part of the cell, keeping the other parts invariant. In the case of PSCs, the nucleation and crystal growth processes of the perovskite layer are influenced by the contact in which the perovskite is deposited, even if the same deposition procedure is employed. In this sense ...
