Out of more than 70 winning projects, the PolyU submission “High Performance Solution-Processed Perovskite Solar Cell Towards Sustainable Development” not only won First Prize in the Energy, Environmental and Chemical Engineering Category, but it was also selected as the only Grand Prize winner from the Innovation Stream of the competition.

The project was praised for the potential of its new approach in the further development of producing high-quality, high-efficiency perovskite solar cells. Solar energy is an important source of renewable energy for industrial production and domestic consumption. Perovskite solar cells are the most promising type of photovoltaic technology and are a game changer for converting sunlight into electrical energy due to their low fabrication cost, high power conversion efficiency, and the flexibility offered by tunable bandgaps, and a facile manufacturing process. As a result, the novel method developed to produce high performance perovskite solar cells has the potential to make a significant contribution to sustainable development globally.
