Photogeneration and photovoltaic properties of polyimides with extended charge delocalisation in polymer chains

摘要

The photogeneration and photovoltaic properties of soluble polyimides seria that contain monotype electron donor units with gradually increased size in their chains, had been studied. It is shown that photogeneration quantum yield is increased with initially formed positive charge delocalisation increasing with simultaneous rising of photovoltaic activity. The spectral sensitization and magnetic field spin effects had been studied also.
