NREL Develops Switchable Solar Window

By: Robin Whitlock The new windows rely on advanced materials such as perovskites and single-walled carbon nanotubes. The technology responds to heat by transforming from transparent to tinted and as the window darkens, it generates electricity. The colour change is driven by molecules of methylamine that are reversibly absorbed into the device. When solar energy […]
