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.
