Semi-transparent Perovskite Solar Cells for Four-Terminal Perovskite/CIGS Tandem Solar Cells …
Tandem solar cells that combine perovskite (PVK) top cells and Si, Cu(In,Ga)(Se,S)2 (CIGS), and other bottom cells have attracted much attention for increasing the efficiency of solar cells. To use the PVK solar cells as the top cells, their metal electrode needs to be replaced with a transparent conductive layer such as indium …
