ABSTRACT:
The present invention discloses a photovoltaic device comprising a portion containing three layers disposed between two electrodes, at least one of which is light transmittable; wherein said three layers consist of a first layer of organic electron acceptor material, a second layer of organic electron donor material and a third layer of organic electron donor material different from the material of the second layer; or a first layer of organic electron donor material, a second layer of organic electron acceptor material and a third layer of organic electron acceptor material different from the acceptor material of the second layer, the sequence of the three layers being counted from a light incident side; and the device having a high photoelectric conversion efficiency.
