The present application discloses an alkenyl side chain-conjugated indo-difuran-based polymer material, a preparation method and application thereof, and the structural formula of the alkenyl-side chain-conjugated indo-difuran-based polymer material as follows: where R is n-hexyl, n-octyl, , , n-hexadecyl, , , , Or other alkanes, aromatic hydrocarbons, n is 9~20; in addition, the series of polymers PIDF‑TCx‑BT designed and synthesized by the present invention have higher conjugated plane, higher HOMO energy level, and wider light harvesting ability And a better electron energy level, wherein with the polymer PIDF-TC6C8-BT and PIDF-TC16-BT that the side chain is 2-hexyldecyl and hexadecyl as examples, it is found that the alkenyl side of the present invention is prepared by testing. The photoelectric conversion efficiency of more than 7% can be obtained under the optimized treatment of the cell prepared by the chain-conjugated indo-difuran-based polymer material, which has a large photovoltaic potential. |
