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..
