摘要

Perylene-diimide (PDI)-based NFA could be synthesized via a few steps with high yields, and exhibit outstanding chemical robustness and photostability, which is suitable for the commercialization of organic solar cells (OSCs). Nowadays, the power conversion efficiency (PCE) of PDI-based OSCs has exceeded 11% and run into the bottleneck. It is time to summarize the latest achievements and find the clue to overcome the challenges for further improving the PCE of PDI-based OSCs. In this review, we summarize the latest achievements in PDI-based OSCs and highlight those potential strategies for further improving the photovoltaic performance of PDI-based OSCs, including fine-tuning the stacking behaviors and absorption spectra of PDI-based NFAs and the developments of narrow bandgap donor materials which are compatible with PDI-based NFAs. New record of PCE is anticipated and new application of PDI-based OSCs worths exploring.
