The use of flatpanel solar photovoltaics FPV is growing dramatically as costs decrease. By contrast, more efficient concentrated PV systems CPV, which focus direct sunlight onto a single point, have not been widely adopted because of their high cost, large size, and expensive tracking systems.
Solar technology offers great potential in terms of supplying the worlds 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 uptodate review of solar concentrators and their benefits to make solar technology affordable.

Each coupling element is oriented to direct its specific beam of light towards highefficiency, multijunction solar cells. Further system efficiency is gained by capturing diffuse light in a secondary layer. The system also includes a secondary layer that captures diffuse sunlight, increasing its overall efficiency.
OSCs using energy transfer or phosphorescence best preserve power efficiency at high optical concentration high G. However, both processes yield slightly lower performance at low G. Energy transfer decreases spectral coverage, and phosphorescence decreases the potential opencircuit voltage in the attached solar cell.
Concentrator Solar Cell with World39s Highest Conversion Efficiency of 44.4. Sharp Corporation has achieved the world39s highest solar cell conversion efficiency 2 of 44.4, using a concentrator triplejunction compound solar cell. These solar cells are used in a lensbased concentrator system that focuses sunlight on the cells to generate electricity.
Improved energyconversion efficiency directly reduces such costs, with increased manufacturing volume likely to drive down the additional costs associated with implementing higher efficiencies
Singlejunction flatplate terrestrial solar cells are fundamentally limited to about 30 solartoelectricity conversion efficiency, but multiple junctions and concentrated light make much higher
title 34IIIV multijunction solar cells for concentrating photovoltaics34, abstract 34Concerns about the changing environment and fossil fuel depletion have prompted much controversy and scrutiny. One way to address these issues is to use concentrating photovoltaics CPV as an alternate source for energy production.

The Fraunhofer Institute for Solar Energy Systems ISE, Soitec, CEALeti and the Helmholtz Center Berlin jointly announced today having achieved a new world record for the conversion of sunlight into electricity using a new solar cell structure with four solar subcells. Surpassing competition after only over three years of research, and entering the roadmap at world class level, a new record
Research into concentrator photovoltaics has taken place since the mid 1970s, initially spurred on by the energy shock from a mideast oil embargo. Sandia National Laboratories in Albuquerque, New Mexico was the site for most of the early work, with the first modernlike photovoltaic concentrating system produced there late in the decade. Their

Enhancing the efficiency of transparent dyesensitized solar cells using concentrated light good photocurrent conversion efficiency, short energy payback time and tunable optical properties , on the solar cell, the concentrators may be classified as low concentration systems, medium concentration systems and high concentrator systems
Concentrated solar power CSP, also known as concentrating solar power, concentrated solar thermal systems generate solar power by using mirrors or lenses to concentrate a large area of sunlight onto a receiver. Electricity is generated when the concentrated light is converted to heat solar thermal energy, which drives a heat engine usually a steam turbine connected to an electrical power
