The present invention relates to a novel polymer material for a high-efficiency organic thin film solar cell and a high-efficiency organic thin film solar cell using the same. More specifically, the present invention relates to an electron-donor functional group-containing compound represented by the following general formula Wherein the electron-withdrawing functional group-containing compound represented by one of the general formulas (5) and (8) is repeatedly introduced repeatedly. NRR, O, SiRR ', PR, S, GeRR', Se or Te; R and R 'are the same or different and each is C1-30 linear or branched alkyl group of; Y are each the same or differently, H, F, Cl or CN, at least one Y in each formula is F, and Cl, or CN; R 1, R 2, R 3, R R 4 , R 5 , R 6 , R 7 , R 11 and R 12 are the same or different and each is a linear or branched alkyl group having C 8 to 30; and n is an integer of 1 to 3, |
