Novel coating that cools solar cells to boost efficiency

  • Three engineers including one of Indian-origin from Stanford University have invented a novel transparent coating that cools solar cells to boost solar panel efficiency. The invention shunts away the heat generated by a solar cell under sunlight and cools it in a way that allows it to convert more photons into electricity. The discovery addresses a problem that has long bedevilled the solar industry: The hotter solar cells get, the less efficient they become at converting the photons in light into useful electricity.
