Perovskite solar cells shouldn’t work as well as they do—but they do. Scientists have now discovered that defects inside the material actually help, creating networks that separate and guide electric ...

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 ...

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 ...
