Synergistic effect of Mn on bandgap fluctuations and surface electrical characteristics in Ag-based Cu2ZnSn(S,Se)4 solar cells

In Cu2ZnSn(S,Se)(4) photovoltaic devices, the exceptionally high density of 2Cu(Zn) + Sn-Zn donor defects may induce bandgap fluctuations and thus limit V-oc and PCE enhancement. We have previously reported that the partial substitution of Ag for Cu in Cu2ZnSn(S,Se)(4) provides a promising way to ef...
