Research may make solar PV cheaper

Research may make solar PV cheaper | Le flux d'Infogreen.lu | Scoop.it

Researchers at the University of Alberta in Canada believe they have created one of the cheapest nanoparticles yet developed for solar photovoltaics, and it could help to further reduce the price of solar power technology.

Solar panel breaks "third of a sun" efficiency barrier

Solar panel breaks "third of a sun" efficiency barrier | Le flux d'Infogreen.lu | Scoop.it

Embattled photovoltaic solar power manufacturer Amonix announced on Tuesday that it has broken the solar module efficiency record, becoming the first manufacturer to convert more than a third of incoming light energy into electricity – a goal once branded "one third of a sun" in a Department of Energy initiative. The Amonix module clocked an efficiency rating of 33.5 percent.

 

During a period of testing by the National Renewable Energy Laboratory back in May, a peak efficiency of 34.2 percent was achieved, which Amonix claims is the highest ever reached by a PV module under real-world conditions. However, Amonix is only now drawing attention to the breakthrough, which saw its own record of 30.3 percent efficiency broken.

 

Amonix modules employ concentrated photovoltaics (CPV) technology, which add optical whizbangery such as mirrors and lenses to concentrate more direct sunlight onto individual solar cells. The technology is not to be confused with concentrated solar power, which applies similar optical technology to solar thermal systems which heat water, but also generate electricity with the addition of a heat engine.

How Crowdfunding Solar is Keeping the Lights on in Detroit

How Crowdfunding Solar is Keeping the Lights on in Detroit | Le flux d'Infogreen.lu | Scoop.it

As the costs of solar technologies decrease, the opportunities for innovative solutions to community problems are increasing. Economic hardships have hit America’s communities hard and, in many communities, electricity prices continue to rise as spending on local public services continues to fall. From 2010 to 2011, the state and local sectors contracted by 3.4 percent, the largest contraction since World War II and that contraction continues to be felt in neighborhoods across the country. Spending cuts have come in all shapes and sizes; some cities have reduced the local police force, while others have slashed the budgets for local fire departments.
