Kesterite/Si Tandem Structure for Unassisted Overall Solar Fuel Production

该项目旨在开发用于光电化学二氧化碳还原以生产太阳能燃料的Kester ite/Si串联装置。它有望揭示p-n异质结的光电化学机制，从而促进太阳能的利用和温室气体的减少。预计的成果包括交付用于有效减少二氧化碳的高性能凯斯特石光电阴极，用于整体无辅助太阳能燃料生产的凯斯特石/硅串联设备，以及深入了解结构与性能的相关性，以指导未来的异质结光电阴极设计。该项目应该会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行业方面带来重大好处。

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.
