economic medium high efficiency concentrator in manchester

Many researches showed that the cost of the energy produced byphotovoltaic(PV)concentratorsis strongly reduced with respect to flat panels, especially in those countries that have ahighsolar irradiation. The cost drop comes from the reduction of the expensivehigh-efficiency photovoltaicsurface through the use of opticalconcentratorsof the solar radiation

    high-concentration systems (hcpv) - fraunhofer ise

    We develophighconcentration photovoltaic systems that allow III-V multi-junction solar cells to be used for terrestrial applications. To do so, we analyze and assess optical components that concentrate sunlight by a factor of 300-1000 before it is turned into electrical energy in III-V multi-junction solar cells
