Abstract

We present the results of the investigations of photo galvanic effect in Methyl Red (MR) doped nematic liquid crystal (LC). The photocurrent appears under the action of the active pulsed irradiation. The photocurrent amplitude depends on the cell thickness, temperature, concentration of MR, cell's lifetime and beam propagating direction. Our investigations showed the appearance of the adsorbed MR molecules layer on the boundary surface. We suppose the spatial charge separation in the adsorbed layer of dye molecules.
