The development of photovoltaics aims to further increase the efficiency of solar cells
. One corresponding technology is CPV solar cells, which stands for Concentrated Photovoltaics. This technology concentrates the sunlight on the solar cell by means of lens technology or concave bent mirrors. As a result, the solar cells receive many times more sunlight and generate correspondingly more energy. The efficiency of CPV solar cells is therefore also over 40 %, in contrast to solar cells made of monocrystalline silicon
, whose efficiency is less than 20 %.Low Concentration Photovoltaics (LCPV), Medium Concentration Photovoltaics (MCPV) and High Concentration Photovoltaics
(HCPV). LCPV solar cells work with a light concentration two to one hundred times higher. These solar cells dissipate the heat generated without additional measures. In addition, the concentration lenses can concentrate the sunlight at different angles of incidence on the solar cell. MCPV solar cells operate with a light concentration of between one hundred and three hundred times, and HCPV solar cells have concentration values of up to one thousand times.
