Abstract
An organic PV solar cell that has an anode double interlayer situated between an electrode and an organic photoactive layer displays superior power conversion efficiency over that of equivalent devices with an anode single interlayer. The anode double layer can comprise a hole extraction layer adjacent to the anode and an organic hole accepting electron blocking material layer that comprises an aromatic amine compound with a plurality of N atoms. The hole extraction layer can be a metal oxide or an n-type organic semiconductor.
