Reducing carrier recombination loss by suppressing Sn loss and defect formation via Ag doping in Cu2ZnSn(S,Se)4 solar cells Reducing carrier recombination loss by doping Ag in Cu2ZnSn(S,Se)4 solar cells

In this study, we analyzed the effect of the position of Ag in the stacked precursor structure of CZTSSe solar cells. Five precursor structures were designed by adding a 5-nm-thick...
