Abstract:An essential role is played by the charge selective layers, in particular, the hole transport layer (HTL) in determining the performance of perovskite solar cells (PSCs). HTLs contribution is even more substantial in the inverted PSCs (p-i-n) as it also affects the crystallization process of the overlayer perovskite deposition. We probed the influence of HTL on inverted PSCs and quantify the role through admittance spectroscopy, and established the photovoltaic performance correlation with the microstructure o… Show more
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.
