Essay

The thesis is dedicated to study of a conditions of ions and photoelectrochemical processes on semiconductors in concentrated polysulfide solutions. It is shown, that at large concentration of alkali and sulfide there is a derivation of an ion pair. Tthe optimal composition of electrolyte for usage in photoelectrochemical converters is obtained. As a result of modification of GaAs and InP surface with CdS nanoparticles the value of a sunlight conversion efficienty 23 % is obtained.
