Abstract

Organic solar cells (OSCs) in terms of power conversion efficiency (PCE) and operational lifetime have made remarkable progress during the last ten years by improving the active layer materials and introducing new interlayers. The newly developed wide bandgap organic donor and low bandgap acceptor m...
