摘要：

In this work, the influence of Se proportion on structural and photovoltaic characteristics of the spray pyrolysis deposited CZTSSe film, and superstrate solar cell device are reported. We observe that the sulfur to selenium ratio significantly impacts the crystallinity and concomitant electrical properties of CZTSSe films. The higher amount of Se leads to better device performance. We found that the superstrate solar cell devices with S/(S + Se) ratio of about 0.2 achieved a power conversion efficiency (PCE) of 3.1%, which is among the highest for the spray pyrolysis deposited solid state CZTSSe solar cells of superstrate architecture.
