摘要

FIELD: power engineering.;SUBSTANCE: use to convert the energy of electromagnetic waves of the sunlight into electrical energy by silicon monocrystals. Core of the invention is in the fact that a method is proposed for increasing the efficiency of converting the energy of the absorbed light flux of electromagnetic waves into the electrical one by a converter created on the basis of a silicon monocrystal without a stationary photosensitive layer in the form of a p-n or a n-p transition associated with the formation of shear high-frequency ultrasonic waves in it by creating longitudinal sinusoidal high-frequency ultrasonic waves on the front of its absorbing surface with the amplitude of 4.0–10.0 V by a piezoelectric element from lithium niobate excited by a high-frequency ultrasonic generator of sinusoidal signals with a variable amplitude and the frequency of about 29.5 mHz.;EFFECT: ensuring the possibility of increasing the efficiency of converting the light flux into electrical energy.;5 cl, 4 dwg
