Enhanced Performance of Close-Spaced Sublimation Processed Antimony Sulfide Solar Cells via Seed-Mediated Growth.

ABSTRACT: Antimony sulfide (Sb₂S₃) has attracted much attention due to its great prospect to construct highly efficient, cost-effective, and environment-friendly solar cells. The scalable close-spaced sublimation (CSS) is a well-developed physical deposition method to fabricate thin films for photovoltaics. However, the CSS-processed absorber films typically involve small grain size with high-density grain boundaries (GBs), resulting in severe defects-induced charge-carrier nonradiative recombination and further large open-circuit voltage (V_OC) losses. In this work, it is demonstrated that a chemical bath deposited-Sb₂S₃ seed layer can serve as crystal nuclei and mediate the growth of large-grained, highly compact CSS-processed Sb₂S
