Abstract
This work describes the electrical characteristics of thin film sandwich cells with vanadyl phthalocyanine complex as a photoactive material in air and in water vapors. The characteristics are altered by the incorporation of an ultrathin metallic layer in phthalocyanine, so that the cells with the aluminum layer in the presence of mixed water/ammonia vapors may generate a significant output power in dark. The effect is assigned to the contribution of mobile ions appeared owing to electrochemical reactions at the metallic interlayer.
