Researchers in Germany report a new world record for the conversion of sunlight into electricity using a new solar cell structure with four solar subcells. A new record efficiency of 44.7% was measured at a concentration of 297 suns, indicating that 44.7% of the solar spectrum's energy, from ultraviolet through to the infrared, is converted into electrical energy. The achievement is being hailed as a major step towards reducing the costs of solar electricity.
Findings show carbon pollution from power plants can be cut cost-effectively by using wind, solar and natural gas. It’s less costly to get electricity from wind turbines and solar panels than coal-fired power plants when climate change costs and other health impacts are factored in, according to a new study.
Engineers are using a falling particle receiver to more efficiently convert the sun’s energy to electricity in large-scale, concentrating solar power plants.
Using colloidal lead sulfide nanocrystal quantum dot substances, researchers have achieved the highest recorded open-circuit voltages for quantum dot solar cells to date.
High school and college students got a recruiting call today to join the Solar Army and help solve one of the 21st century’s greatest scientific challenges: finding the dirt-cheap ingredients that would make sunlight a practical alternative to oil, coal and other traditional sources of energy.
Researchers have demonstrated a new mechanism for extracting energy from light, a finding that could improve technologies for generating electricity from solar energy and lead to more efficient optoelectronic devices used in communications.
Renewable energy holds the promise of reducing carbon dioxide emissions. But there are times when solar and wind farms generate more electricity than is needed by consumers. Storing that surplus energy in batteries for later use seems like an obvious solution. But a new study finds that when you factor in the energetic costs, grid-scale batteries make sense for storing surplus solar energy, but not for wind.
A revolutionary new solar energy technology that turns water into steam without boiling the entire container of water has become the basis for new devices to sanitize medical and dental instruments and human waste in developing countries, scientists say.
Materials science engineers changed the electronic properties of new class of materials -- just by exposing it to light.
Researchers have come up with a new technique for improving the connections between stacked solar cells, which should improve the overall efficiency of solar energy devices and reduce the cost of solar energy production. The new connections can allow these cells to operate at solar concentrations of 70,000 suns' worth of energy without losing much voltage as 'wasted energy' or heat.
A study of the photovoltaic industries in the US and China shows that China's dominance in solar panel manufacturing is not driven solely by cheaper labor and government support, but by larger-scale manufacturing and resulting supply-chain benefits.
Engineers have developed a way to measure electron band offset in nanodevices using laser spectroscopy.
Researchers have found a way to make dye-sensitized solar cells more energy-efficient and longer-lasting.
Theoretical simulations reveal that layered semiconductors with magnetic interfaces are potent catalysts for solar energy capture and conversion.
Researchers have found that abundant materials in the Earth's crust can be used to make inexpensive and easily manufactured nanoparticle-based solar cells.
Researchers have developed a way to interface a molecular hydrogen-producing catalyst with a visible light absorbing semiconductor. With this approach, hydrogen fuel can be produced off a photocathode using sunlight.
Leveraging the amazing natural properties of the Morpho butterfly's wings, scientists have developed a nanobiocomposite material that shows promise for wearable electronic devices, highly sensitive light sensors and sustainable batteries.
A new study indicates that by 2025 wind and solar power electricity generation could become cost-competitive without federal subsidies, if new renewable energy development occurs in the most productive locations.
