A study on the photovoltaic effect in liquid crystal cells formed on a semiconductor wafer

Abstract

The photoevoltaic effect in liquid crystal cells with a semiconductor wafer used as one of the electrodes are investigated. A mechanism of the photovoltaic effect is then considered in which elecrtons and positive holes in semiconductor wafer and positive ions and negative ions in the liquid crystal layer is generated bv the illumination of the incident light, which plays an important role for the electric generation. The solution of some dyestuffs enhances the effect.
