High‐performance Cu 2 ZnSnS 4 photovoltaic devices are demonstrated using electrodeposition of metal stacks and annealing of a CuZnSn precursor in a sulfur atmosphere. A champion electroplated Cu 2 ZnSnS 4 solar cell achieves a power conversion efficiency of 7.3%, which is a record efficiency for electrodeposited Cu 2 ZnSnS 4 solar devices. The device performance points to electrodeposition and annealing as a low‐cost and viable approach to earth‐abundant solar cell fabrication.
