Cd-Free Cu2ZnSnS4 solar cell with an efficiency greater than 10% enabled by Al2O3 passivation layers

Environmentally friendly earth-abundant Cd-free Cu2ZnSnS4 (CZTS) solar cells have recently achieved increasing power conversion efficiency by using ZnSnO as the buffer layer. However, the large open circuit voltage (Voc) deficit remains the key concern. Here, we report a Cd-free CZTS solar cell that...
