Abstract/Summary:


In order for photovoltaic (PV) technology to contribute significantly to society’s energy supply, device components must be abundant, cheap and environmentally benign. One candidate that satisfies these criteria as well as exhibiting almost ideal electronic properties is the photo-absorber tin sulfide. SnS is reported to have a higher optical absorption coefficient and a more suitable band gap for light absorption at peak intensity than current commercially available materials. However, the record device efficiency published for SnS PV cells is only 2.0 % to date,[1] far below those obtained for similar absorbers. But there are very recent conference reports of up to 6% efficiency. We employ a combination of single crystal growth, optical, photoemission charcterization and firstprinciples calculations to study tin sulfide with the goal of identifying its potential for PV technology.
