| Research Abstract |
We have developed organic-metal charge transfer complex (CT complex) thin films for near infrared light driven organic solar cells. We found that bathocuproine (BCP)- Ca complex shows semiconductor-like properties. A strong chemical interaction between BCP and Ca induces a large number of charge transfer and a peculiar electric structure. Another good material that we found is lead phthalocyanine- Ag complex, which demonstrated high photoconductivity. For these complexes, however, a control of the structural properties is required for the enhancement of their photoelectric conversion efficiency.
