Use of a New Organic Complexing and Buffer Agent for Zn(S,O) Deposition for High-Efficiency Cu(In,Ga)Se 2 -Based Solar Cells

Chemical-bath-deposited (CBD) Zn(S,O) is one of the most studied and promising Cd-free buffer layers for Cu(In,Ga)Se2 (CIGSe) -based solar cells and has already demonstrated its potential to lead to high-efficiency solar cells. However, CBD Zn(S,O) presents some inconveniences compared with a classic CBD cadmium sulfide (CdS) buffer. Indeed, Zn(S,O) deposition time, important ammonia concentration...
