Sharp Develops Solar Cell with World's Highest Conversion Efficiency of 37.9%

Sharp Develops Solar Cell with World's Highest Conversion Efficiency of 37.9% | Ecoeficiencia | Scoop.it

Sharp Corporation has achieved the world's highest solar cell conversion efficiency*1 of 37.9%*2 using a triple-junction compound solar cell in which three photo-absorption layers are stacked together.

Sharp achieved this latest breakthrough as a result of a research and development initiative promoted by Japan’s New Energy and Industrial Technology Development Organization (NEDO)*3 on the theme of "R&D on Innovative Solar Cells." Measurement of the value of 37.9%, which sets a new record for the world's highest conversion efficiency, was confirmed at the National Institute of Advanced Industrial Science and Technology (AIST).

Ultra-Efficient Solar Power

Ultra-Efficient Solar Power | Ecoeficiencia | Scoop.it

Harry Atwater thinks his lab can make an affordable device that produces more than twice the solar power generated by today’s panels. The feat is possible, says the Caltech professor of materials science and applied physics, because of recent advances in the ability to manipulate light at a very small scale.Solar panels on the market today consist of cells made from a single semiconducting material, usually silicon. Since the material absorbs only a narrow band of the solar spectrum, much of sunlight’s energy is lost as heat: these panels typically convert less than 20 percent of that energy into electricity. But the device that ­Atwater and his colleagues have in mind would have an efficiency of at least 50 percent. It would use a design that efficiently splits sunlight, as a prism does, into six to eight component wavelengths—each one of which produces a different color of light. Each color would then be dispersed to a cell made of a semiconductor that can absorb it.

Australia: 100 Percent Renewable Energy Could Be Cost-Effective by 2030

Australia: 100 Percent Renewable Energy Could Be Cost-Effective by 2030 | Ecoeficiencia | Scoop.it

The study concluded that at a 5 percent discount rate, 100 percent renewables become cost-effective between 2030 and 2034, with a CO2 price of $50 to $60 in Australian dollars (U.S. dollars are roughlyequivalent). At a 10 percent rate, its between 2035 and 2045 with a CO2 price of $70 to $100.

Solar-powered plane makes successful test flight | Ecoeficiencia | Scoop.it

MOUNTAIN VIEW, Calif. — A solar-powered plane that has wowed aviation fans in Europe took to the skies today over the San Francisco Bay area in a successful test flight.

Considered the world's most advanced sun-powered plane, the Solar Impulse took off from Moffett Field in Mountain View at first light for a two-hour practice run in advance of a planned multi-city, cross-country tour.

New CCCL White Paper: Encouraging Energy Efficiency through the Clean Air Act

A new white paper by CCCL examines the myriad ways that the CAA can be used to promote energy efficiency. One of the chief components of the CAA is the setting of National Ambient Air Quality Standards (“NAAQS”) for non-hazardous pollutants, which are set by EPA but generally implemented by the adoption of implementation plans by each state. These state implementation plans (“SIPs”) can include energy efficiency programs so long as they provide quantifiable, additional, enforceable, and permanent reductions of emissions of the pollutant being regulated.
