摘要

In this study, we firstly synthesized ternary CuSnSe nano ink by novel organic solvent polyetheramine by solvent-thermal reflux method. CuSnSe thin films were prepared by solvent-thermal reflux method for Cu/Sn ratio in three different ratios of 2/1, 1.8/1, and 1.4/1. Structure, surface morphology, composition, and electrical and optical properties at different process conditions were measured. SEM micrograph also shown that with Cu/Sn ratio increase, surface have many voids, not uniform for grain size and shape due to nonuniform grown second phase. In this experiment we display a nonvacuum based method to fabricate CuSnSe based device has been made to study copper factor on device performance. Furthermore, the selenization caused volume expansion of the film, and larger grains were consequently obtained in the CZTSe thin film. We proved that our method has great potential for further optoelectronic device due to low cost, high throughput and composition dependent properties.
