Abstract:As an alternative to lead-based perovskites, Cs 2 AgBiBr 6 is an emerging lead-free double perovskite (DP), which has shown promise in the field of optoelectronics owing to its nontoxicity, high stability, and superior photoelectric properties. Herein, we demonstrate the growth of a highly crystalline and uniform Cs 2 AgBiBr 6 thin film via chemical vapor deposition (CVD). By tuning the growth temperature, we successfully obtained Cs 2 AgBiBr 6 thin films of high structural and compositional uniformity, confir… Show more
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...
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
