Kesterite/Si Tandem Structure for Unassisted Overall Solar Fuel Production

本项目旨在开发用于光电化学二氧化碳还原的Kesterite/Si串联装置，以生产太阳能燃料。有望揭示p-n异质结的光电化学机理，从而促进太阳能利用和温室气体减排。预期的成果包括交付一种高性能的kesterite光电阴极，用于有效减少二氧化碳，kesterite/Si串联装置用于整体无辅助太阳能燃料生产，以及对结构-性能相关性的深入理解，以指导未来的异质结光电阴极设计。该项目将在最大限度地减少化石燃料消耗、提高能源安全和扩大清洁能源产业方面带来显著效益。

This project aims to develop Kesterite/Si tandem device for photoelectrochemical carbon dioxide reduction to produce solar fuels. It is expected to reveal the photoelectrochemical mechanism of the p-n heterojunction, thereby promoting solar energy utilisation and greenhouse gas reduction. Expected outcomes include delivery of a high-performance kesterite photocathode for efficient CO2 reduction, a kesterite/Si tandem device for overall unassisted solar fuel production, and an in-depth understanding of structure-performance correlation to guide future heterojunction photocathode design. This project should provide significant benefits in minimising fossil fuel consumption, increasing energy security, and expanding the clean energy industry.
