有機色素ドープ液晶セルにおける偏光に依存した光起電力特性

抄録

It has been reported that a remarkable photovoltaic output is generated in an organic dye-doped liquid crystal cells. We have realized that the polarity of the photovoltaic output flips depending on the light irradiation direction based on the Dember effect, in which the internal electric field is generated due to the difference in mobility between anions and cations. In this study, the polarization-dependent photovoltaic characteristics are measured. As a result, it was found that a larger photovoltaic power is generated when the polarization direction of the incident light is parallel to the orientation direction of LC molecules.
