Modern CPV systems operate most efficiently in highly concentrated sunlight (i.e. concentration levels equivalent to hundreds of suns), as long as the solar cell is kept cool through the use of . Diffuse light, which occurs in cloudy and overcast conditions.
According to theory,properties allowto operate more efficiently in concentrated light than they do under a nominal level of . This is because, along with a proportional increase in the generated current, there also occurs a logarithmic.
CPV systems are categorized according to the amount of their solar concentration, measured in "suns" (the square of the ). Low concentration PV (LCPV)Low concentration PV are systems with a solar concentration of.CSP technologies use mirrors to reflect and concentrate sunlight onto a receiver. The energy from the concentrated sunlight heats a high temperature fluid in the receiver. This heat - also known as thermal energy - can be used to spin a turbine or power an engine to generate electricity.
