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.Read moreRead less

This project will create redox-sensitised ion-accessible dense graphene to improve the energy density of supercapacitors (SCs). The energy density of SCs is a bottle neck for long-lasting power supply to vehicles, small devices and mobile electronics. By incorporating a redox coordination framework in shrunk graphene to increase the charge storage capacity and speed up the charge movement and further incorporating ionic liquids in the tailored electrodes, the project will produce SC’s with higher operating voltage and longer cycle life. Such SCs will possess dramatically high energy density, without compromising the power density. This project will improve the efficiency of modern electronics through the development of the next generation of SCs.Read moreRead less
