A relatively new kind of semiconductor, layered atop a mirror-like structure, can mimic the way that leaves move energy from the sun over relatively long distances before using it to fuel chemical reactions. The approach may one day improve the efficiency of solar cells. “Energy transport is one of the crucial steps […]
Researchers at the U.S. Department of Energy’s (DOE’s) National Renewable Energy Laboratory (NREL) made a technological breakthrough and constructed a perovskite solar cell with the dual benefits of being both highly efficient and highly stable. The work was done in collaboration with scientists from the University of Toledo, the University of Colorado-Boulder, […]
Solar cells manufactured from materials known as “perovskites” are catching up with the efficiency of traditional silicon-based solar cells. At the same time, they have advantages of low cost and short energy payback time. However, such solar cells have problems with stability – something that researchers at Linkoping University, together with international collaborators, have […]
Clean water is essential for human survival. However, less than 3% of fresh water can be used as drinking water. According to a report published by the World Meteorological Organization, there is scarcity of drinking water for approximately 1 billion people worldwide, which is expected to rise to 1.4 billion by 2050. […]
Creating and storing solar power is increasingly important as the United States moves toward its goal of net-zero carbon emissions by 2050. Erin Ratcliff, a University of Arizona associate professor of chemical and environmental engineering and chemistry and biochemistry, is leading one of the Department of Energy’s Energy Frontier Research Centers, to […]
Solar cells are vital for the green energy transition. They can be used not only on rooftops and solar farms but also for powering autonomous vehicles, such as planes and satellites. However, photovoltaic solar cells are currently heavy and bulky, making them difficult to transport to remote locations off-grid, where they are much needed. […]
