An Optimization Path for Sb₂(S,Se)₃ Solar Cells to Achieve an Efficiency Exceeding 20.

ABSTRACT: Antimony selenosulfide, denoted as Sb₂(S,Se)₃, has garnered attention as an eco-friendly semiconductor candidate for thin-film photovoltaics due to its light-absorbing properties. The power conversion efficiency (PCE) of Sb₂(S,Se)₃ solar cells has recently increased to 10.75%, but significant challenges persist, particularly in the areas of open-circuit voltage (V_oc) losses and fill factor (FF) losses. This study delves into the theoretical relationship between V_oc and FF, revealing that, under conditions of low V_oc and FF, internal resistance has a more pronounced effect on FF compared to non-radiative recombination. To address V_oc and FF losses effectively, a phased optimiz
