Organic photovoltaic device

Abstract

In an organic power generating device that generates electricity by receiving light, a positive electrode and a negative electrode, at least one of which has transparency, a power generating layer which is formed of a mixture of an electron donor material and a hole donor material and generates electricity upon reception of light and disposed between the positive electrode and the negative electrode, and an inorganic layer which has a work function larger than that of the positive electrode and is disposed between the power generating layer and the positive electrode, are provided. Accordingly, an efficiency to take off electric charges from the power generating layer can be increased, so that the organic power generating device with high efficiency and long life can be obtained.
