INFLUENCE OF NO_2 ADSORPTION ON PHOTOVOLTAIC PERFORMANCE OF PHTHALOCYANINE THIN FILM SOLAR CELLS

摘要

Schottky type solar cells leased on phthalocyanine (Pc) thin films were fabricated, and their photovoltaic performance was investigated in various ambient atmospheres. Most of cells prepared in this study showed a good rectification and photovoltaic effects in the visible wavelength region. The introduction of NO_2 gas into the measuring chamber was confirmed to increase the current both in dark and under light illumination. However chemical reaction between the Al electrode and NO_2 formed some oxide and deteriorated the Schottky barrier, resulting in an increase in cell resistivity. SF_6 gas also showed similar effects on the call performance.
