“Development of Perovskite, Organic and Tandem Optoelectronics”

Metal-halide perovskite solar cells have emerged as a highly promising photovoltaic technology due to their exceptional optoelectronic properties, low cost and solution processability. However, their operational lifetimes often lag behind those of commercial silicon-based solar cells. We have shown organometallic functionalisation of perovskite devices to deliver outstanding efficiencies and enhanced stability, enabling performance that competes with commercial photovoltaics and photodetectors. In addition, we have demonstrated that organometallic functionalisation of organic solar cells also improves both efficiency and device stability.

“Development of Conductive and Thermoelectric Materials”

The need for new materials that enable low-power neuromorphic computing and efficient thermoelectric energy harvesting is becoming increasingly urgent as waste heat generated by information and computing technologies continues to rise. By developing compounds capable of supporting high electrical performance, we aim to provide a pathway to reducing energy losses and help power the next generation of wearable and embedded technologies. Our work focuses on the design, synthesis and development of organic and organometallic compounds to produce switchable, large-area thin-film materials for energy harvesting, cooling, sensing and thermal management on both rigid and flexible substrates.
