Laboratory of Nanostructure Solar Cells

Research has been carried out to improve the structure of a GaInP/Ga(In)As/Ge thriple-junction solar cell. Metamorphic structures, which can be used to create a metamorphic GaInAs subcell as part of a cascade multi-junction solar cell, have been developed and investigated. The influence of the built-in Bragg reflector on the degradation rate of solar cell characteristics was investigated.

A solar tracking system has been developed for ground-based concentrator photovoltaic power plants, which allows minimizing the time the platform turns to its operating position. Profiles of Fresnel lenses used in concentrator photovoltaic modules, providing a decrease in peak power and a uniform distribution of intensity over the photoactive surface of a photocell, have been obtained. The efficiency of solar energy conversion of 32.9% in modules with optical concentrators and multijunction photoconverters is reached.

Implemented results of research: 

During 2017-2020 the laboratory conducted young scientists schools in the field of highly efficient solar energy conversion. The school was intended for senior students, masters and postgraduate students of specialized areas.

On the basis of the laboratory, scientific practice of students and postgraduates takes place.
