Efficiency of solar electro stations with solar energy concentrators

The analysis of different types of photoelectric converters (PEC) included in solar electrostations with solar energy concentrators showed that concentration coefficient increase leads to PEC working temperature increase, and as a consequence to a significant decrease of efficiency of different types of photoelectric converters and to their degradation as well. This fact should be taken into consideration when choosing an optimal degree of solar emission for PEC and for realization of heat extraction system in energy installations with solar energy concentrators.
