A molecular approach to solar power

April 13, 2014

Switchable material could harness the power of the sun — even when it’s not shining. Learn more from the MIT News Office.

A powerful arc lamp is used to simulate sunlight on a sample of photoswitchable molecules, driving structural changes at the molecular level. A portion of the light's energy is stored with each structural change. The progress of these changes can be tracked by monitoring the molecules' optical properties. Image courtesy of the researchers
