Three-layered organic solar cell with a photoactive interlayer of codeposited pigments

Three-layered organic solar cell with an interlayer of codeposited pigments of n-type perylene tetracarboxylic derivative (Me-PTC) and p-type metal-free phthalocyanine (H2Pc) in between the respective pigment layers, was fabricated. Two times larger photocurrent compared to the double-layered cell without an interlayer was obtained due to the efficient carrier photogeneration in a codeposited layer. The power conversion efficiency reached 0.7% under the intense white light of 100 mW cm−2.
