摘要：

In this study, we have successfully incorporated a small molecular acceptor, Y-LC, with conjugated pi-extension as a secondary acceptor in the PM6:BTP-eC9-based organic photovoltaics. The performance of the device was significantly promoted from 18.45% in the binary system of PM6:BTP-eC9 to over 19% in the ternary system with a minimal Y-LC loading. This enhancement in performance can be attributed to the alloy-like structures of acceptors and the optimized active layer morphology, which leads to improved hole and electron mobilities, thereby suppressing charge recombination, and finally resul...
