Bright future of polymerizing small-molecule acceptors in realizing high performance all-polymer solar cells
All-polymer solar cells(all-PSCs)are prepared with a sandwich device structure based on a binary blend of a polymer donor and a polymer acceptor(Fig.1),and have attracted intensive research attention as a potential renewable photovoltaic technology[1,2].As compared to the PSCs with small molecule acceptors(SMAs),all-PSCs show pronounced advantages of superior mechan-ical flexibility/stretchability and improved device stability[3,4].Thus,they are more attractive for the applications in wearable and portable electronics.After the first report ofthe all-PSCs in 1995 using cyano-substituted polypheny-lenevinylene as the polymer acceptor[5,6],researchers have focused their efforts on the design of new polymer acceptors,such as rylenediimide[7],B←N bridged bipyridine[8],and cyanobenzothiadiazole-based polymer acceptors[9].However,before 2017,the power conver-sion efficiency(PCE)of the all-PSCs was limited by the weak absorbance of the polymer acceptors in the near-infrared region[10].
