Abstract

Three all-fused-ring acceptors with different conjugated backbone are designed as acceptor materials for organic solar cells. It is found that the horizontally extended conjugation of all-fused-ring acceptors leads to better photovoltaic performance compared to the vertically extended analogue. The results provide a guideline for designing high-performance and stable all-fused-ring acceptor materials.
