We have screened ~33,000 non-magnetic insulators/semiconductors for which there was a computed bandstructure in the Materials Project (as of early 2018) for potential use as photovoltaic absorbers.

Like many studies, we employ a "funnel" approach of increasingly stringent screening criteria that require increasingly expensive calculations. We computed high-level parameters, isotropic-equivalent optical absorption spectra, and electronic density of states (DOS) for the ~800 candidate phases passing the intermediate screens. The absorption spectra DO include a scissor operation to correct the fundamental bandgap using the Delta-sol method, whereas the density of states DO NOT.
