Abstract
High efficiency CZTS-based thin film solar cells are achieved by cation substitution and sol-gel method. Two approaches are presented here: 1) the substitution of Zn with Cd and 2) the substitution of Cu with Ag. For Cd-doped CZTS (i.e. CZCTS) the efficiency of CZCTS thin film solar cell can be improved from 9.24% to 10.66% by careful modification of alloys composition and interfaces between TCO/CdS/CZTS. For Ag-doped CZTS thin film solar cells, the improvement in power conversion efficiency can be correlated with the Voc and crystallinity improvements. Thus the limitations in CZTS system, such as Voc deficit, secondary phases, crystallinity and antisite defects, can be alleviated to some degree by using cation substitution.
