A new world record for the conversion of sunlight into electricity using a new solar cell structure with four solar subcells has been achieved by a German-French collaboration consisting of the Fraunhofer Institute for Solar Energy Systems ISE, Soitec, CEA-Leti and the Helmholtz Center Berlin.
Graphene has extreme conductivity and is completely transparent while being inexpensive and nontoxic. This makes it a perfect candidate material for transparent contact layers for use in solar cells to conduct electricity without reducing the amount of incoming light - at least in theory.
Scientists at Michigan Technological University have replaced expensive platinum, a key ingredient for a novel type of solar cells, with a new material: low-cost 3D graphene.
The German Karlsruhe Institute of Technology (KIT) is putting its theoretical findings in renewable energy and electric energy storage into practice by building the largest photovoltaics facility for self-consumption in Germany and produce energy from renewable sources for its own supply.
Why is the power grid so sensitive to high temperatures? It's quite simple really. First, we certainly love our air conditioners, and air conditioners demand a lot of power. Second, power is generated at only a few places in the country, and yet our air-conditioned homes and businesses and factories...
In a leap towards flying around the world using solar power alone, Solar Impulse landed in New York this weekend – an important landmark for the Swiss project.
The dream of a solar-powered world recently took a major step forward. On 24 June, in a joint announcement with the US White House and IBM, the Harvard Clean Energy Project released a database of 2.3 million organic compounds - 35,000 of which have promising properties for high-performance semicondu...
Until now, designers of buildings have no choice but to use black or bluish-gray colored solar panels. With the help of thin-film technologies, researchers have now been able to turn solar cells into colorful creations.
Sharp Corporation has achieved the world's highest solar cell conversion efficiency of 44.4%, using a concentrator triple-junction compound solar cell. These solar cells are used in a lens-based concentrator system that focuses sunlight on the cells to generate electricity.
Australian scientists have produced the largest flexible, plastic solar cells of the Southern continent – ten times the size of what they were previously able to – thanks to a new solar cell printer that has been installed at CSIRO.
To develop an affordable photovoltaic system capable of concentrating solar radiation 2,000 times and converting 80 percent of the incoming radiation into useful energy, the Swiss Commission for Technology and Innovation has awarded Swiss scientists a $2.4 million (2.25 million CHF) grant
The experimental solar-powered plane Solar Impulse, created by Swiss inventors Bertrand Piccard and André Borschberg ,is reportedly headed for the United States where it will fly coast-to-coast. The "Across America" tour lifts off in May, says a report in the Huffington Post.
