摘要: Publisher Summary The use of high efficiency III–V multijunction solar cells in flat-plate modules on Earth would currently be too expensive. However, the expensive cell area can reduced by using a cost-efficient concentrating optic. In recent years, many companies have implemented this idea placing into terrestrial concentrator systems. Most these systems concentration factors above 400, which enable significant cost reduction and also lead to higher efficiencies. addition their space systems, are used several niche applications. One is thermophotovoltaics (TPV). such light from an emitter other than sun converted electricity photovoltaic cells. The either flame or material that heated temperature between 1000° C 1500° burning fuel. As emitted spectrum shifted toward longer wavelengths compared sun, TPV need rather small band gap. could, for example, industrial waste heat generation offer advantages like high-power density outputs, in-phase supply demand, potential low cost.
