A methodology for performing high throughput, computational screening for materials usable as thin film absorbers is disclosed. The method includes selecting a search set of inorganic compounds, and sequentially filtering the search set with a set of filters. The filters exclude materials on the basis of optical and electrical properties such as band gap, carrier effective mass and the presence of low-formation-energy, deep defects that can act as strong nonradiative recombination centers.
