Abstract

On page 7427, J. Kim, H. Hiroi, T. K. Todorov, D. B. Mitzi, and co-workers report high-efficiency Cu2 ZnSn(S,Se)4 solar cells by applying In2 S3 /CdS double emitters. This new structure offers a high doping concentration within the Cu2 ZnSn(S,Se)4 solar cells, resulting in substantial enhancement in the open-circuit voltage. The 12.4% device is obtained with a record open-circuit voltage deficit of 593 mV.
