The invention discloses a thiophene indanone and carbazole based A-pi-D-pi-A type small-molecule solar cell acceptor material and a preparation method thereof. The type of acceptor material has the structure in a general formula I (please see the specification for the formula); and the acceptor material takes carbazole as a central nuclear structure, groups such as thiophene, furan and benzene serve as a pi bridge, and aldehyde groups at the two ends and active sites of electrondrawing groups, namely thiophene indanone are subjected to a condensation reaction at the normal temperature and normal pressure to obtain symmetric target molecules. A synthesis method of the type of thiophene indanone and carbazole based A-pi-D-pi-A type small-molecule solar cell acceptor material is simple, reaction conditions are easy to control, the yield is high, universal applicability is achieved, efficient synthesis can be achieved; and the thiophene indanone and carbazole based A-pi-D-pi-A type small-molecule solar cell accep
