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.
