Low-cost polymer acceptors with noncovalently fused-ring backbones for efficient all-polymer solar cells
文献摘要:
The polymerization of fused-ring acceptors(FRAs)to afford their corresponding polymeric acceptors for high-performance all-polymer solar cells(all-PSCs)has achieved remarkable progress in the past few years.However,due to the high degree of synthetic complexity for the monomer,the high-cost of these polymeric acceptors may limit their commercial applications.Thus,it is urgent to develop inexpensive and high-performance polymeric acceptors for all-PSCs.Herein,two novel polymeric acceptors(PBTzO and PBTzO-2F)have been designed and synthesized by copolymerization of noncovalently fused ring acceptors(NFRAs),which were employed in all-PSCs for the first time.Upon introducing the"noncovalently conformational locks(NoCLs)"in the backbone and selective fluorination of the end-group,photophysical and electrical properties,and solid-state packing properties of the NFRAs have been rationally tuned.As a result,the PBDB-T:PBTzO-2F based devices presented an excellent power conversion efficiency(PCE)of 11.04%,much higher than that of PBTzO based ones due to the increased charge generation and extraction,improved hole transfer and carrier mobilities,and reduced energy loss.More importantly,PBTzO-2F exhibited a much lower synthetic complexity(SC)index and higher figure-of-merit(FOM)values than the high-performance fused-ring acceptor based polymer acceptors(FRA-PAs)due to the simpler structures and more effective synthesis.This contribution provided a novel idea to achieve low-cost and high-performance all-PSCs.
