The invention discloses an electron acceptor material of an organic photovoltaic cell, a preparation method and application thereof. The acceptor material has a compound of the following general chemical structure: , where n is the repeating number of thiophene units, n=1-6; A is R1 and R2 are the same or different H, C 1 -C 30 alkyl chain, C 1 -C 30 alkoxy chain, C 5 -C 30 cycloalkyl, C 2 -C 30 heteroalkyl chain, O, N or S; * is the connection position. The oligothiophene containing aldehyde terminal groups is prepared first, and strong electron-withdrawing groups are introduced into the two ends of the oligothiophene through the condensation reaction of aldehyde groups. The photoelectric property of the acceptor material of the invention is adjustable, and has important application potential as an electron acceptor material of an organic photovoltaic cell, and the preparation method is simple, the preparation cost is low, and the application range is wide. |
