Purdue researchers are making solar energy more efficient


Today’s Video of the Day from EurekAlert describes new technology developed at Purdue University that will make solar heat-to-electricity generation more efficient.

Currently, solar power is used for less than two percent of the electricity generated in the United States. This innovation could put solar heat in direct competition with fossil fuels.

“Storing solar energy as heat can already be cheaper than storing energy via batteries, so the next step is reducing the cost of generating electricity from the sun’s heat with the added benefit of zero greenhouse gas emissions,” said Kenneth Sandhage, Purdue’s Reilly Professor of Materials Engineering.

The study is published in the journal Nature.
