Investigation on nonequilibrium electronic processes in heterostructures on basis Si and chalgenide semiconductors. Influence of radiation on their physical properties. Obtaining of thinfilm solar cells on a chalcogenide semiconductors and investigation on their properties. Diffusion processes and formation of defects in solid  states. Investigation on influence laser irradiation  and radiation semiconductors and opitaxsial structures.

The method of deep levels transient spectroscopy there were  investigated the deep levels of nickel in silicon. Parameters of these levels and their nature are determined. It is shown, that: a) at evaporating on surface silicon of solar cells of two layer coats ZnS + Na₂O₃the magnification of a photoelectric at 60%, efficiency =15% (for solar cells without a coat h=9,3%) is observed; b) in thin film solar  transformers on a basis nCdS-pCdTe, obtained by a method vacuum evaporation in quasi-closed volume, effectency = 9,6% and I= 22mA/cm².
