A photoelectrochemical cell consisting of two semiconducting electrodes covered by orienting SiO_{x} layers and filled with merocyanine solutions in nematic liquid crystal was constructed. Dye molecules were oriented as a result of the guest-host effect. Generation of photocurrent by two components of polarized light gives different values of photocurrent amplitude but anisotropy of photocurrent is lower than that of absorption in the region of a free base form of dye. It is explained by dominant participation of a protonated form of dye in the photocurrent generation. The last form exhibits a lower degree of orientation than the free base form of dye.
