SOLAR POWER PHOTOSYSTEM (VERSIONS) Russian patent published in 2009 - IPC F24J2/42 

FIELD: heating.

SUBSTANCE: invention relates to solar power engineering, in particular to solar power systems with solar radiation concentrators to produce electric energy by photovoltaic conversion of solar energy. The solar power photosystem comprises a sun-following subsystem and photovoltaic modules mounted on the subsystem. Each module comprises at least one primary lens solar concentrator, at least one photo cell with photoactive central zone surrounded by passive contact zone and at least one secondary concentrator. The secondary concentrator can be made as a hollow focon or truncated tetrahedral pyramid with inner reflecting surfaces or as a solid focon or truncated tetrahedral pyramid. First two secondary concentrators are fixed on the passive contact zone by a current collecting bus projecting beyond the secondary concentrator. The wide section of the secondary concentrators can be top-covered by a glass plate coated with an antireflection coating on both sides. The upper end face of the secondary concentrator can be covered by a metal screen set on the above plate. The metal screen can be fixed on the above plate by folding the outer edge of the metal screen onto the outer surface of the secondary concentrator. The third and fourth secondary concentrators are fixed on the surface of the photoactive central zone of the photo cell by optically transparent glue.

EFFECT: high efficiency of solar radiation conversion into electric energy without precise sun-orientation of the modules.
