Perovskite solar cells

Perovskite solar cells present opportunities to achieve next-generation high efficiency and low-cost solar PV devices, with their efficiency rate rapidly rising from below 4% to over 25% in only a decade. Perovskites provide the potential for remarkable cost-reduction through solution-based and low-temperature fabrication. 

The commercialisation of perovskite solar cells is grappling with concerns about their durability. Our group focuses on tackling the critical stability issues of perovskite solar cells through the development of novel precursor solution engineering and surface passivation technologies. Our cutting-edge characterisation techniques can provide insight into the degradation mechanism, therefore accelerating the development of stability improvement strategies. Further, our research covers the development of perovskite top cells for silicon-based tandem cells, single-crystalline perovskite solar cells, and the encapsulation for perovskite solar PV devices. In working to minimise these properties, our research focuses on the application and optimisation of thin films in a wide range of solar cells in order to minimise optical and electronic losses in power. The best results can be achieved when the cell composition of thin films can be controlled with atomic layer precision, and this can be achieved by atomic layer deposition in our labs.
