Heterojunction Lithiation Engineering and Diffusion-Induced Defects Passivation for Highly Efficient Sb2(S,Se)3 Solar Cells

High-quality heterojunction is crucial for achieving the high power conversion efficiency (PCE) in the antimony selenosulfide (Sb2(S,Se)3) solar cells. Here, we introduce lithium fluoride (LiF) doping of the precursor solution...
