摘要：

Concentrator photovoltaic units based on Fresnel lenses and secondary concentrators-hollow focons made of sheet aluminum-have been developed. To increase the efficiency of sunlight conversion, the optimal configuration of focons was determined and the photoelectric characteristics of the units were examined. The use of focons provided an increase in the admissible misorientation angle of the unit from +/- 0.45 degrees (without a focon) to +/- 0.8 degrees (with a focon) and in the unit efficiency from 29.2% (without a focon) to 32.8% (with a focon).
