Cpv cooling systems employing forced air circulation achieved cpv temperature as low as 75 c being comparable to temperatures achieved by single sun pv without thermal management systems . a waterbased cpv cooling system restricted cpv temperatures to 60 c with an electrical conversion efficiency of 39.7 223 being 4 times the standard.
Cpv modules are typically made with highefficiency multijunction cells, which are optically addressed in order to concentrate the foremost amount of sunlight 15. although cpv modules have a reduced cell area, these modules work at preferred optimal conditions in geographic areas that are exposed to high levels of direct normal irradiance.
Cpv systems are likely to be relatively low cost electricity generators because the expensive solar cells are replaced with less costly structuralsteel holding mirrors or lenses. however, early cpv systems showed the importance of optical efficiencies as optical losses sometimes lowered the efficiency of cpv systems by 15 to 20.
Energy cost of the system, lowcost optical design with high efficiency and the fewest elements is required. the cpv technology promises not only to reduce the cost of the overall system, but also increases the amount of power produced 3. a concentration system consists of three parts focusing optics, solar tracker, and receiver.
