Facile in situ synthesis of double perovskite Cs₂AgBiBr₆/WS₂ heterostructure and interfacial charge transfer mediated high-performance ultraviolet photodetection

Abstract

While lead-based halide perovskites have demonstrated exceptional performance in photovoltaic and other optoelectronic applications globally, the inherent toxicity of lead (Pb) has consistently posed a barrier to widespread commercialization. As...
