Abstract
An amine-containing difluoro benzotriazolyl polymer, preparation method, and use thereof are provided; the polymer has a structure as represented by formula (I), both Rand Rare alkyls from Cto C, n is an integer from 10 to 50. In the polymer of the present disclosure, because the 1,2,3-benzotriazole solar cell material contains two fluorine atoms, the HOMO energy level is reduced by 0.11 eV, the fluorine-substituted 1,2,3-benzotriazole has two imido groups with strong electron-withdrawing property; the 1,2,3-benzotriazole is a heterocyclic compound with strong electron-withdrawing property, and an alkyl chain can be easily introduced to the N-position of the N—H bond of the benzotriazole; the functional group of the alkyl chain can improve solar energy conversion efficiency, thus solving the low efficiency problem of the solar cell made from the solar cell material.
