Abstract

In this work CZTSSe absorber films were prepared by spin coating technique followed by selenization at optimized suitable condition. The structural properties and phase purity of the films were analyzed by XRD and Raman spectroscopy, surface morphology of the films was analyzed by SEM and AFM. Elemental composition was analyzed by energy dispersive x ray spectroscopy. Phase pure CZTSSe films with the required photovoltaic properties was obtained by selenizing the precursor films at 450 °C for 30 min with the optimal precursor drying condition. Prototype CZTSSe solar cell was fabricated and its performance were studied systematically. The highest device efficiency of 4.9% with Voc=321 mV, Jsc=30 mA/cm2 , and FF=51% was obtained for spin coated CZTSSe device. It was observed that precursor drying condition significantly influence the performance of devices.
