To make these solar panels, Indian companies need PV cells—which are the small parts that convert sunlight into electricity. Since India doesn’t yet make enough of these cells on its own, it is ...

Plug-in solar panels could soon give households a simpler way to generate their own electricity, without paying for a full rooftop solar installation. Instead of a large array of panels fixed to the ...

Imagine a display that harvests ambient light when it is not actively in use, offsetting some of its own energy consumption. The materials physics shows that this is possible, the same semiconductor ...

One of the hindrances to large-scale solar adoption, especially in cities, is where to install the chunky panels. Rooftops? Skyscraper walls? Vast open spaces that dense urban centers barely have in ...

A new solar breakthrough may overcome a long-standing efficiency barrier. Researchers used a “spin-flip” metal complex to capture and multiply energy from sunlight through singlet fission. The result ...
