Principle. In Concentrating Photovoltaics (CPV), a large area of sunlight is focused onto the solar cell with the help of an optical device. By concentrating sunlight onto a small area, this technology has three competitive advantages: Requires less photovoltaic material to capture the same sunlight as non-concentrating pv

IntroductionMinimizing energy cost (€/kWh) is necessary for the success of concentrated photovoltaic energy (CPV). Key to minimizing this cost is an efficient and low cost optical design, goals best met with the fewest elements and the maximum tolerances, but always maintaining the high concentration (>500) that offsets the cost of expensive high-efficiency multi-junction solar cells
