These Solar Cells Produce Electricity at Night

IEEE Spectrum: By taking advantage of the temperature difference between a solar panel and ambient air, engineers have made solar cells that can produce electricity at night. Compared to the 100 to 200 watts per square meter that solar cells produce…

Extreme air pollution hampering India’s solar electricity generation

E&T Magazine: India will struggle to meet a target of generating 100 gigawatts of solar power this year as high levels of atmospheric pollution are hindering the country’s ability to generate energy, a study has found. Atmospheric pollution reduces solar power…

PV Moisture-Wicking Tech Gives New Meaning to “Solar Farm”

IEEE Spectrum: Growing food crops in arid climates is an energy-intensive endeavor. Saudi Arabia, for instance, sits on vast pools of both oil and water, and the country uses its oil to pump water up to the surface for irrigation. Researchers…

Europe’s Solar Fuels on the Rise

IEEE Spectrum: By combining several optical and chemical-processing innovations, a European consortium is developing a pilot-scale system that will turn carbon dioxide and green hydrogen into fuels around the clock, using sunlight, artificial lighting, and plasmonics. The reactor that the project, called Spotlight, develops is designed to work with the…
