Abstract
An organic solar cell is provided. The organic solar cell includes a photoactive layer in which a low molecular weight conjugated compound as a first organic semiconductor material is mixed with an appropriate amount of a second organic semiconductor material. The first organic semiconductor material includes both electron donors and electron acceptors. The presence of the electron donors and the electron acceptors in the first organic semiconductor material improves the morphology of the photoactive layer, leading to high efficiency of the organic solar cell.
