Organic Solar Cell Comprising an Intermediate Layer with Asymmetrical Transport Properties

An organic photovoltaic cell comprising:

• two electrodes and
• an organic photoactive layer comprising a conjugated polymer and a fullerene, the organic photoactive layer being disposed between the two electrodes,
• wherein the organic photovoltaic cell is configured to be oriented to an incident light source, wherein the electrode disposed between the organic photoactive layer and the incident light is transparent or semitransparent, and
• the organic photovoltaic cell further comprises two intermediate layers each intermediate layer having asymmetrical conductivity and each intermediate layer being disposed between each of the two electrodes and the organic photoactive layer.
