Abstract

This article presents an in-depth insight into the most efficient cathode buffer layers (CBLs) in conventional and inverted organic solar cells (OSCs). The CBL can play a critical role in improving the short circuit current density (Jsc) and fill factor (FF) of the devices by minimizing the contact...
