Abstract:An electroluminescence (EL) anomaly singular spot was observed in an industrystandard InGaP/GaAs multi-junction solar cell (MJSC). Affected by this singular spot, the spatially resolved subcell current distributions were found to exhibit unique opposite characteristics, which we call "defect-induced current coupling." Herein, we conducted systematic investigations to reveal the defect-induced current coupling phenomenon, for the first time, through the absolute EL imaging technique. Specifically, a modified ca… 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.
