Active selenium-driven confined crystallization and carrier dynamics in high-efficiency ultrathin semi-transparent Sb₂Se₃ solar cells.

ABSTRACT: To overcome the limited environmental stability of organic semi-transparent photovoltaic (STPV) devices, developing robust inorganic thin-film absorbers has become a critical research focus. Antimony selenide (Sb₂Se₃), with its Q1D crystal structure, excellent optoelectronic properties, and mechanical flexibility, is a promising candidate for STPV applications. However, thinning the absorber to enhance visible transmittance often degrades crystallinity, weakens preferred orientation, and increases defect density. Here, we present a dual-pathway device-engineering strategy that integrates KOH-assisted chemical-bath thinning of the CdS buffer layer with rapid thermal evaporation combined with magnetron sputtering of active selenium (Se). The introduced active Se atoms e
