摘要：

Three-layered organic solar cell having a codeposited interlayer of phthalocyanine and perylene pigment sandwiched between respective pigment layers shows two times larger photocurrent compared to two-layered cells without the interlayer. This phenomenon was investigated by means of the microwave photoconductivity measurement which can directly observe the amount of photogenerated free carriers from its microwave absorption. Codeposited film of both pigments showed larger microwave photoconductivity signal compared to that for each single pigment films. Since the microwave signal is basically free from the carrier transport process, the above photocurrent enhancement is concluded to be due to the sensitization of carrier generation.
