As established experimentally, the illumination of n-GaSe layered semiconductor electrodes in acid and neutral environments enhances anode and cathode reactions. Irradiation within the solar range leads to the increasing of the electrons recoil from electrode and to the selective dissolution of Ga, Se, stimulating their passing into the ionic state. Neutral and acid liquid environments such as films or drops, which are formed on the surfaces of these electrodes, affect the surface characteristics of the investigated semiconductors. Therefore, investigation of a change of the electrochemical properties and structure on nanolevel is necessary to clarify principle of operation of new photoelectrochemical cells for sun energy transformation.
