The Clean Energy Project (CEP) was a virtual high-throughput discovery and design effort for the next generation of plastic solar cell materials that has finished.

It studies millions of candidate structures to identify suitable compounds for the harvesting of renewable energy from the sun and for other organic electronic applications.

The project searched for the most suitable organic compounds with which to make solar cells, the best polymeric membranes with which to make fuel cells, and how best to assemble the molecules for such devices.

On June 24, 2013, the Clean Energy Project released its database to the public and the research community.

The release was featured on the White House Blog[1] and by several news organizations including the MIT Technology Review.
