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.

Organic solar cell and method for fabricating the same

The present disclosure relates to a novel polymer compound and a method for preparing the same. More particularly, the present disclosure relates to a novel conductive low band gap electron donor polymer compound having high photon absorptivity and improved hole mobility, a method for preparing the same and an organic photovoltaic cell containing the same. Since the conductive polymer compound as a low band gap electron donor exhibits high photon absorptivity and superior hole mobility, it can be usefully used as a material for an organic optoelectronic device such as an organic photodiode (OPD), an organic thin-film transistor (OTFT), an organic light-emitting diode (OLED), an organic photovoltaic cell, etc. as well as in the development of a n-type material.
