In the present work, sputtered In2S3 buffer layers are deposited on Cu(In,Ga)Se2 absorbers with no or minimal sputter damage. Buffer deposition at slower sputter rates (0.22 A/s) with H2S as a reactive gas improved the interface quality and uniformit

Article

Chalcopyrite solar cells achieve efficiencies above 23%. The latest improvements are due to post-deposition treatments (PDT) with heavy alkalis. This study provides a comprehensive description of the effect of PDT on the chemical and electronic struc
