Reshaping the solar spectrum to turn light into electricityMon, 27 Jul 2015 18:02:31 EDT
Solar energy could be made cheaper if solar cells could be coaxed to generate more power. A huge gain in this direction has been made by a team of chemists that has found an ingenious way to make solar energy conversion more efficient. The researchers combined inorganic semiconductor nanocrystals with organic molecules to 'upconvert' photons in the visible and near-infrared regions of the solar spectrum.

Researchers have developed a method that could improve medical imaging and cancer treatments and increase the efficiency of commercial solar cells by 25 to 30 percent. New finding could lead to cheap, efficient metal-based solar cellsThu, 23 Jul 2015 10:10:08 EDT
Although the domestic solar-energy industry grew by 34 percent in 2014, fundamental technical breakthroughs are needed if the U.S. is to meet its national goal of reducing the cost of solar electricity to 6 cents per kilowatt-hour. New research could make it easier for engineers to harness the power of light-capturing nanomaterials to boost the efficiency and reduce the costs of photovoltaic solar cells.

A grid of sensors embedded into an innovative building insulation activates specific façade components to optimise energy savings while improving aesthetics. Perovskite solar technology shows quick energy returnsMon, 20 Jul 2015 13:33:00 EDT
In the solar power research community, a new class of materials called perovskites is causing quite a buzz, as scientists search for technology that has a better 'energy payback time' than the silicon-based solar panels currently dominating the market. Now, a new study reports that perovskite modules are better than any commercially available solar technology when products are compared on the basis of energy payback time.
