This project aims to develop cost-effective Cu2ZnSnS4 nanocrystals for two solar devices for electricity and hydrogen production. The copper-zinc-tin-sulphide (Cu2ZnSnS4) nanoparticle for solar cells has been less than two per cent efficient for years and photoelectrochemical devices have been recently recognised but less explored. The combined innovative modification of its nanocrystals, and grain growth approach for enhancing light absorption and photogenerated carrier collection efficiency should elucidate underlying mechanism of and provide solutions to the problem which has baffled researchers in above areas for several years. The intended resulting simple, cost-effective solar-driven electricity and hydrogen devices should make significant contributions to goals of commercially viable storage of solar energy and solutions to global energy and environment issues.
