Copper zinc tin sulfide (Cu2ZnSnS4, CZTS) is a promising non-toxic and earth-abundant material for thin-film solar cell. However, its efficiency is hindered by a large open-circuit voltage deficit (VOC) due to intrinsic defects related to potential fluctuations and band tail states. By partially and...
