Abstract

Abstract In recent years, Cu–Ag–Bi–I quaternary lead-free perovskites have emerged as promising candidates for optoelectronic applications, offering an environmental alternative to traditional lead-based perovskites. This review presents a comprehensive analysis of the current advancements in the synthesis, structural characterization, and photoelectric properties of Cu–Ag–Bi–I compounds, with a focus on their photoelectric applications, including solar cells, indoor photovoltaics, and photodetectors. The unique combination of metal cations in Cu–Ag–Bi–I materials leads to tunable bandgaps, high absorption coefficients, and favorable charge transport properties, positioning them as versatile materials for…
