The photoelectrochemistry of semiconductor studies the process of various natures that occur at a semiconductor–electrolyte solution interface under the action of electromagnetic radiation. These processes include (1) electrode reactions caused by the photoexcitation of the electron ensemble of a solid and (2) electrode reactions at semiconductors caused by the photoexcitation of reactants in the solution and in the adsorption layer. The theoretical developments are influenced by the concepts borrowed from semiconductor physics and the physics of surfaces. The photoelectrochemistry of semiconductors are affected to a greater degree by progress achieved in the study of metal electrodes. The photoemission of electrons from semiconductors into solutions and electroreflection at a semiconductor–electrolyte interface are discussed in the chapter. The processes inverse to light-stimulated electrode reactions can also be referred to as the “processes of the photoelectrochemistry of semiconductors.” Such processes include electrode reactions accompanied with light emission.
