New material could help produce highly efficient solar cells

A new type of material for next-generation solar cells eliminates the need to use lead, which has been a major roadblock for this technology. Solar...

Scientists find the most efficient way to turn fat and sewage into natural gas

North Carolina State University researchers have developed what is, to date, the most efficient means of converting sewage sludge and restaurant grease into methane. After...

‘Messy’ production of perovskite material could increase solar cell efficiency

Discovery means simpler and cheaper manufacturing methods are actually beneficial for the material’s use in next-generation solar cells or LED lighting. Scientists at the University...

Scientists close a loophole for iron-based solar cells

An international study led from Lund University in Sweden shows that 30 percent of the energy in a certain type of light-absorbing iron molecule...

Carbon dioxide capture and use could become a new global business

Capturing carbon dioxide and turning it into commercial products, such as fuels or construction materials, could become a new global industry, according to a...

Scientists find new way to extend the life of perovskite solar cells

Researchers believe they’ve overcome a major hurdle that’s kept perovskite solar cells from achieving mainstream use. Perovskites are crystals with cube-like lattices known to be...

How some bacteria ‘eat’ electricity to survive

Ever since scientists discovered that certain microbes can get their energy from electrical charges, researchers have wondered how they do it. Bacteria don’t have mouths,...

Electric cars could be recharged in 10 minutes soon

Electric vehicle owners may soon be able to pull into a fueling station, plug their car in, and, in 10 minutes, drive out with...

Solar and wind energy could reduce groundwater use, says study

California's switch to solar, wind energy reduced reliance on hydropower, natural gas. Solar and wind farms are popping up around the country to lower carbon...

Scientists put the “solve” in “solvent” for lithium-sulfur battery challenge

Lithium-ion batteries represent the majority of batteries in consumer electronics and electric vehicles. Today, scientists are looking for new chemistries that could improve the energy...
