Cu2ZnSnS4 (CZTS) is a promising photovoltaic material due to its easy processability, earth-abundant constituent elements, high absorption coefficient, and a suitable bandgap. Further development of CZTS-based solar cells is currently limited by a low open-circuit voltage (VOC). Although there is a...
