Performance and Reliability of Multijunction III-V Modules for Concentrator Dish and Central Receiver Applications

Applicability of silicon micro-finned heat sinks for 500× concentrating photovoltaics systems

“…Several solutions have been proposed to reduce the cost of PV [2][3][4]. Among these, concentrating photovoltaics (CPV) has been firstly proposed in early 1970s [5] and consists of the replacement of part of the expensive semiconductor area with cheaper concentrating materials [6].…”

A novel solar concentrator system for combined heat and power application in residential sector

“…To reproduce defined concentration level and spot shape, a mosaic of low cost flat mirrors mounted on a unique frame is often employed. Mirrored dishes with diameters ranging from few to tens of meters have been developed and commercialized during the last ten years working at typical concentration of 500 suns [18][19][20], even if recent studies show a good perspective of increasing the concentration factor towards 1000 suns and beyond [21]. Advantages of the reflective optics are the lack of chromatic aberration, which gives a higher optical efficiency if compared to systems embedding lenses, a lower cell operating temperature (caused by the necessary active cooling) and the possibility to cogenerate both electric current and heat given by the cooling system itself.…”

Enhancing the efficiency of solar concentrators by controlled optical aberrations: Method and photovoltaic application

“…with solar flux up to hundreds times the ambient value. Reflective dish concentrators with diameters ranging from few meters to few tens of meters have been already proposed and are at the beginning of their commercial development working at typical concentrations of 500Â [12][13][14].…”
