摘要：

Kesterite Cu2ZnSnS4 (CZTS) thin films have been fabricated by an electrodeposition route via sulfurizing sequentially electrodeposited Cu-Zn and Cu-Sn stacked binary alloy layers. The CZTS films exhibit densely packed grains with only minor ZnS secondary phase. Photovoltaic device with the structure of ITO/i-ZnO/CdS/CZTS/Mo/Glass shows the highest power conversion efficiency of 3.67%. The limiting factors of the efficiency are the high series resistance and recombination rate. The ZnS phase, voids at the Mo/CZTS interface and high resistance MoS2 layer have been considered to lead to high series resistance and thereby low J(sc) and FF. (C) 2015 Elsevier B.V.
