New generation high-efficiency
solar power plants
Solar modules and new generation power plants, equipped with Fresnel lenses and sun tracking system will also be produced under the auspices of the project. It will commercialize the outcomes of research conducted in the Ioffe Physical Technical Institute in the field of fundamental scientific and technical principles and technological basis for constructing the main blocks of concentrator solar photovoltaic plants.
The concentrator solar power plants will employ:
1) new generation of cascading solar cells, based on nanoheterostructures for photoelectric conversion of concentrated light;
2) Fresnel lenses, that provide 900-fold solar power concentration;
3) high-precision sun-tracking systems.
The proposed concentrator photovoltaic modules accurately focus the solar light falling on the 50×50 mm Fresnel lens surface to the highly efficient cascade solar cell with size of less than 4 square millimeters. This way solar modules do not overheat due to specially designed naturally cooling heat sinks.
Cascade solar cells used in tandem with the concentrators will be produced with a CVD (chemical vapor deposition) method modified for use with different semiconductor materials on germanium substrate
