electron phototransport, nature of anion, organic photovoltaics, photovoltage, polymethine dyesAbstract
The anion nature of cationic polymethine dyes in polymer composites has been found to affect the photovoltage value. According to the investigations of spectral-luminescent properties, polymethines form contact ion pairs. The difference in the behavior of anions is determined by their ability of the photoinduced electron transfer in these pairs.
