摘　　要：Bulk-heterojunction organic solar cells(OSCs)with physically mixed electron donor and acceptor as photoactive layer have received broad attention due to the advantages of light weight,flexibility,solution-processed fabrication,etc.[1−11].With the rapid development of non-fullerene acceptors,the power conversion efficiencies(PCEs)of OSCs already exceed 19%[12,13].However,the photoactive layer is thermodynamically unstable and tends to form self-aggregated structure,resulting in reduced thermal/light stability during long-term operation.This issue can be tackled via covalently linking donor and acceptor into one material as double-cable conjugated polymers to fabricate single-component organic solar cells(SCOSCs)[14−16].In 2019,Brabec et al.reported that SCOSCs exhibited excellent thermal stability and photostability due to the built-in microstructure[17].SCOSCs have some merits such as simplified fabrication and homogenous viscosity,which can be applied in large-area devices.
