Concentrated Solar Photovoltaics Reduce Long-term Solar Energy Costs

Mila Luleva — Sun, 25 Nov 2012 19:01:11 +0000

RayGen Reseources, a company that provides solar power services, based in Melbourne, was granted a funding of $1.6 million to produce a 2kW concentrated solar photovoltaic (CPV) prototype and a 200kW pilot plant. The new technology is the first ever to combine high efficiency solar cells and a low cost heliostat collector system. This technology […]

San Jose-based SolFocus may serve as a harbinger of things to come for the solar panel industry. Admitting financial difficulty, SolFocus has announced that the latest rounds of venture capital investment have fallen through, and in order to survive, the company needs a buyout. SolFocus manufactures concentrating photovoltaic modules (CPV) which uses lenses or mirrors […]

The world’s most efficient solar panel is here to stay thanks to the collaboration between North Carolina’s Semprius Inc. and the German company Siemens. The device is claimed to use 33.9% of the sunlight it comes into contact with and turns it into electricity, more than the last record of 32% obtained in the Spanish […]

Keeping the land clear for useful projects is vital to some countries that have limited space and that have to manage it as tightly as possible.
If those countries will want to rely on solar power in the future, they'll have to find solutions for managing their solar fields and the land is just not proper for that in some cases. But water bodies are.

Semprius's Micrometric Solar Cells Efficient in Concentrated Photovoltaic Systems

Ovidiu Sandru — Fri, 12 Feb 2010 08:56:40 +0000

Concentrated photovoltaic systems are usually more effective than regular, flat ones, because a lens focuses the sunlight on a smaller surface of some efficient and more expensive solar cells 500 times stronger than the cells would receive in regular operation. Heat is mostly a problem with concentrated PV systems, since it has to be efficiently dissipated through complex and expensive cooling technique.
