Abstract
Partial Cation Substitution In article number 2100441, Cheng–Ying Chen, Kuei–Hsien Chen, Li–Chyong Chen, and co-workers of the National Taiwan University showed the impact of partial cation substitution in a (AgxCu1-x)2ZnSnSe4 absorber-based solar cell. Based on the experimental and theoretical studies, the enhanced photovoltaic efficiency (> 10%) can be attributed to the shallower de-fect states in the Ag-alloyed kesterite material.
