As containing earth-abundant elements,kesterite(Cu_(2)Zn-Sn(S,Se)_(4),CZTSSe)semiconductors have great potential to be low-cost and environmental-friendly inorganic absorbers.However,the record power conversion effici...
Cu2ZnSnS4 (CZTS)/ZnS heterojunctions have been prepared by a successive deposition of ZnS and CZTS thin films by ultrasonic spray pyrolysis technique on glass substrates. The cupric chloride concentration has been v...
Cu2ZnSnS4 (CZTS) is a main candidate material for solar energy conversion through both photovoltaics and photocatalysis based on environmentally friendly elements and with a direct band gap of 1.5 eV. We report the ...
