MIT, Harvard scientists study how to produce solar power without sunlight

By Biz Journals

A team of researchers at the Massachusetts Institute of Technology and Harvard University are working on a technology that wouldn't require sunlight to produce solar power.

The team is developing a material that can absorb the sun's heat and store the energy in a chemical form, ready to be released "on-demand," according to a release.

The technology could be used for heating buildings, cooking or other uses where heat, rather than electricity, is the desired output.

In a release, researchers describe the technology behind the system:

"Some molecules, known as photoswitches, can assume either of two different shapes, as if they had a hinge in the middle. Exposing them to sunlight causes them to absorb energy and jump from one configuration to the other, which is then stable for long periods of time.
