| Outline of Final Research Achievements |
Internal electric field and photovoltaic performance of the Schottky-barrier solar cells made of a Zn-phthalocyanine(ZnPc) thin film were studied. By an insertion of a NTCDA buffer layer between the ZnPc film and transparent electrode, the short-circuit current increased to a 6 times larger value. When PTCBI was used for the buffer layer, an interesting phenomenon was observed, i.e. the photocarrier-generation efficiency in the PTCBI layer was anomalously high. A new experimental technique, Electroabsorption under White Light Illumination(EAWL), was developed, which enabled the measurement of the internal electric field in the device under operation.
