The Clean Energy Project is run by Professor Alán Aspuru-Guzik and his team from the Department of Chemistry and Chemical Biology at Harvard University. They are looking to identify suitable compounds for organic electronic applications and harvesting renewable energy from the sun. The HCEP dataset contains properties for over 2.4 million compounds, derived from density functional theory calculations. Properties in this dataset include principle energy levels, photovoltaic performance parameters, mass and stoichiometric formulas.
