Study of heterostructures of Cu3BiS3-buffer layer measured by Kelvin probe force microscopy measurements (KPFM)1

The interface formed between Cu3BiS3 thin films and the buffer layer is a potentially limiting factor to the performance of solar cells based on Al/Cu3BiS3/buffer heterojunctions. The buffer layers of ZnS and In2S3 were grown by co-evaporation, and tested as an alternative to the traditional CdS dep...
