摘要:
Non-fullerene acceptor (NFA) based organic solar cells (OSCs) are of high efficiency and low energy loss and low recombination features,which is owing to the advantage of non-fullerene acceptors.The photophysics investigation of non-fullerene solar cells,in comparing to fullerene based analogue as well as mixed acceptor ternary blends could help to understand the working mechanism of NFA functioning mechanism.We choose PBDB-T donor,the fullerene derivative PC71BM acceptor,and the non-fullerene acceptor ITIC as the model system,to construct binary and ternary solar cells,which then subject to ultrafast spectroscopy investigation.The charge transfer pathway in binary and ternary blends is revealed.And it is seen that ITIC leads to a faster exciton separation and exciton diffusion.ITIC in blends suppresses the geminate recombination and shows smaller amount of charge transfer states,which is beneficial for the device performance.And the addition of ITIC enhances the crystallinity for both donor and acceptor leads to a morphology change of forming bicontinuous crystalline networks and phase separation.In a consequence,fill factor and Jsc,increase dramatically for the related OSC.
