Nanostructured Cu2ZnSnS4 for solar-driven electricity and hydrogen

该项目旨在开发具有成本效益的Cu2ZnSnS4纳米晶体，用于发电和制氢的两种太阳能设备。用于太阳能电池的铜锌锡硫化物（Cu2ZnSnS4）纳米颗粒多年来的效率不到2%，光电化学设备最近得到了认可，但探索较少。结合创新的纳米晶改性，晶粒生长的方法，以提高光吸收和光生载流子收集效率应阐明的基本机制，并提供解决方案，在上述领域的研究人员多年来一直困扰着。预期产生的简单、具有成本效益的太阳能驱动的电力和氢设备将为实现商业上可行的太阳能储存目标和解决全球能源和环境问题做出重大贡献。

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.
