Abstract:An efficient inverted polymer solar cell (PSC) with a transparent amorphous titanium oxide (TiOx) as an electron transporting layer (ETL) between bottom electrode and photo-active layer, and a tungsten oxide (WO3) inserted as a hole transporting layer (HTL) was fabricated. Introducing of ETL and HTL results in increases in the open circuit voltage (VOC), short circuit current (JSC) and the fill factor (FF). The inverted PSC device with TiOx and WO3 layer showed the higher power conversion efficiency (PCE) than… 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.
