Single-junction Perovskite Thin-Film Solar Cells

This research project aims to enhance the efficiency and stability of single-junction perovskite thin-film solar cells through innovative methodologies. Key areas of focus include the development of advanced interfacial engineering techniques to suppress non-radiative recombination and facilitate charge transport in perovskite solar cells, along with precise regulation of the perovskite crystallisation process. The overarching objectives are to significantly boost power conversion efficiency (PCE), enhance long-term operational stability, and achieve scalable fabrication for large-area applications. This comprehensive approach aims to advance the performance and commercial viability of perovskite solar cells.

Perovskite-based Tandem Solar Cells

Tandem solar cells represent a forefront innovation in photovoltaics, composed of multiple layers of light-absorbing materials engineered to capture specific segments of the solar spectrum. This multilayer design, incorporating materials such as silicon, organic polymers, and kesterite alongside perovskite, enables tandem cells to surpass the efficiency limits of traditional single-junction solar cells. The research focuses on the development of perovskite-based tandem solar cells, leveraging stable wide-bandgap perovskite single junctions pioneered by the research group. 

Organic Functional Materials

This research centres on the design, synthesis, and assembly behaviour of novel organic and polymeric charge transport materials with new structures and functionalities. It also involves the development of interface passivation materials, both of which are intended to enhance the performance, stability, and efficiency of perovskite solar cells. By integrating these advanced materials, the research seeks to significantly improve the operational stability and practical applicability of perovskite solar cells, thereby contributing to their commercial viability.
