Competitive advantage
- Hold world record of 11% for highest efficiency high bandgap pure sulphide Keserite CZTS (Cu2ZnSnS4) solar cells and have established 4 world records for this photovoltaic technology
- Developed 21% efficient low-temperature (<200 °C) processed planar perovskite solar cells with improved stability without encapsulation
- Developed above 30% efficiency III-V/Si tandem solar cells
- Designing and developing new PV materials that are made from environmentally-friendly and earth-abundant materials for Silicon based tandem cells
Impact
- The aim is to make solar photovoltaic more efficient, cost-effective and competitive for the energy market and for their applications in various aspects of our life such as building- and vehicles-integrated PV, and portable power sources
- The breakthroughs in kesterite represent a major advance in developing solar cells that are flexible, stable, cheap and non-toxic
Successful outcomes
- Working with industry partners for building-integrated PV (2015-present)
- Working with industry partners for III-V/Si tandem solar cells (2011-present)
