Environmentally friendly earth-abundant Cd-free Cu 2 ZnSnS 4 (CZTS) solar cells have recently achieved increasing power conversion efficiency by using ZnSnO as the buffer layer. However, the large open circuit voltage ( V oc ) deficit remains the key concern. Here, we report a Cd-free CZTS solar cel...
