Solar Concentrators
Solar technology offers great potential in terms of supplying the world’s energy needs. However, its current contribution to the world is still limited. The main factor is related to high initial cost of building the system. This paper will provide an up-to-date review of solar concentrators and their benefits to make solar technology affordable. It will also analyse on some of the existing sol...
متن کاملComparison of Solar Concentrators
-Even though most variations of solar concentrators have been studied or built at some time or other, an important class of concentrators has been overlooked until very recently. These novel concentrators have been called ideal because of their optical properties, and an example, the compound parabolic concentrator, is being tested at Argonne National Laboratory. Ideal concentrators differ radi...
متن کاملNanostructured, luminescent solar concentrators
Luminescent solar concentrators1 (LSCs), a class of solar-energyharvesting devices, operate slightly differently from traditional photovoltaic (PV) solar cells. Irrespective of the exact nature of the active materials used for their manufacturing, solar cells generate electrical carriers and, hence, a photocurrent. In contrast, LSCs absorb solar photons and re-emit them over a narrow band at lo...
متن کاملHigh Temperature Solar Concentrators
The use of solar energy in technical applications is often constrained due to its low energy density relative to the conventional sources of energy. Optical concentration is one option to increase the energy density of the solar radiation resulting in the possibility to use absorbers with small surfaces. Higher temperatures can be achieved under concentrated conditions, because heat losses are ...
