Abstract

Using binary and ternary chalcogenide nanoparticle solutions as precursors, a bi‐layered CZTSSe film is formed after being annealed in selenium atmosphere. Based on the CZTSSe film, a high efficiency thin‐film photovoltaic device (9.02% conversion efficiency) is made. Detailed characterizations of the device's performance and composition from XPS depth profiling are presented, and based on the results we discuss possible areas for further efficiency improvement.
