Whats on the surface is all that matters ;)…..………. when trying to improve the properties of π-SnS photocathodes

My summer research project is Optimizing Buried Junction Cubic and Orthorhombic SnS Photocathodes. For many years my research group have been searching for semiconductors and solar absorber materials that are non-toxic, abundant, stable, which crystallize at low temperature and are fabricated at low cost, but also have favorable optical and electrical properties for solar energy conversion. Figure 1: π-SnS photocathodes a) before and b) after coating with a passivation and protection layer. When designing a system for solar water splitting it has been proposed that an idealized tandem device, consisting of two semiconductors with band gaps around 1.0 to 1.3 eV and 1.6 to 2.0Read More →
