Abstract: PURPOSE: A polymer is provided to have a band gap with wide and low photoabsorption region, thereby capable of being used for an organic solar cell of high efficiency. CONSTITUTION: A polymer comprises a repeating unit indicated in chemical formula (P1) and (P2). In the chemical formulas, R1 and R2 is respectively a C1-20 linear or branched saturated or unsaturated alkyl group, n is an integer from 1-100,000, and a molecular weight is 500-10,000,000. An organic solar cell comprises the polymer. The polymer is included in a photo-conversion active layer. The photo-conversion active layer additionally comprises fullerene derivatives.
