PURPOSE: A heteroaromatic compound remarkably improves the lifetime, efficiency, electrochemical stability, and thermal stability of an organic solar cell. CONSTITUTION: A compound is represented by chemical formula 1 where L includes chemical formula 2, chemical formula 3, and chemical formula 4, and n is an integer of 1-100,000. An organic solar cell includes a first electrode, a second electrode, and at least one photoactive layer. At least one layer of the photoactive layer includes the compound. A manufacturing method of the organic solar cell includes a step of preparing a substrate; a step of forming a first electrode on the substrate; a step of forming a photoactive layer including the compound, on the first electrode; and a step of forming a second electrode on the photoactive layer. |
