Abstract

Abstract : In the present study, a facile hydrothermal route was successfully implemented for the synthesis of Cu2 Zn1− x In x Sn(S, Se)4 ( x = 0.0 to 0.075 M) (CZITSSe) thin films for solar cells. Abstract : Substitution of the cation is a major focus to diminish the antisite defects and boost the photovoltaic properties of the Cu2 ZnSn(S, Se)4 absorber. In the present study, a facile hydrothermal route was successfully implemented for the synthesis of Cu2 Zn1− x In x Sn(S, Se)4 ( x = 0.0 to 0.075 M) (CZITSSe) thin films for solar cells. The morphology of the CZITSSe was engineered from nanocubes to compact well grown nanoflowers like surface morphology. The improvement in the photocurrent ( J sc ) from 3.09 to 4.26 mA cm −2 associated with the photovoltage ( V oc ) from 386 to 556 mV and accompanying improvement in the conversion efficiency ( η %) from 1.96% to 4.82% were accomplished via Indium (In 3+ ) ion incorporation. The composition CZITSSe ( x = 0.075 M) showed exemplary photoelectrochemical behavior with a highest photoconversion efficiency (PCE) of 4.82%. Further, I – V performance of the deposited photocathode shows conversion efficiency of 2.01 to 5.12% as function of Indium ions incorporation. The improvement in PCE was mainly ascribed to improved crystal quality and suitable band gap energy. The EIS analysis demonstrates that the charge transfer resistance ( R ct ) of the CZITSSe films was reduced with In 3+ ion concentration. This work offers a one-step hydrothermal route that is a prominent way to develop an In 3+ ion substituted Cu2 Zn1− x In x Sn(S, Se)4 photoelectrode for competent solar energy harvesting.
