- •
C-AFM identified the relationship between current leakage and secondary phases in CIGSSe films.
- •
Formation of Cu2−XSe or InSe phases acting as a current pathway and leading to a breakdown in the P-N junction.
- •
An increase in Cu content caused Ga to diffuse toward the surface.
- •
CIGSSe solar cells by sputtering in this study achieved a maximum conversion efficiency of 13.06%.
