摘要：
Copper Zinc Tin Sulfide (CZTS) semiconductor has been used as counter electrode in QDSCs. However, the highest power conversion efficiency (PCE) of the corresponding QDSCs was lower than 4%. Herein, copper-deficient CZTS was synthesized through modified hot-injection method. The as-prepared CZTS is made into counter electrode (CZTS/FTO). PCEs up to 5.75% and 7.64% for CZTS/FTO based CdSe and CdSeTe sensitized QDSCs are obtained, respectively. The excellent photovoltaic performance is associated with the good conductivity and catalytic activity of CZTS. Electrochemical impedance spectroscopy (EIS) and Tafel polarization are used to verify the good electrochemical properties of CZTS/FTO.
