This research develops low-cost gallium arsenide solar-cell manufacturing to accelerate global decarbonization. Gallium arsenide absorbs light far more efficiently than silicon, potentially enabling cheaper and less capital-intensive solar production. By improving scalable manufacturing methods, the work aims to reduce the cost of expanding renewable-energy infrastructure needed to combat climate change.

This research investigates zinc batteries as a safer, cheaper alternative to lithium batteries. By studying the microscopic passive layer formed between zinc and electrolyte, it identifies mechanisms that improve performance and prevent failure. The work aims to enable more reliable, ethical, and fire-safe energy storage technologies through detailed materials analysis.

This research transforms agricultural waste into biochar-based activated carbon for batteries and supercapacitors. By replacing costly materials, it improves energy storage performance while reducing costs, offering a sustainable and affordable solution that turns waste into valuable resources for future energy technologies.

This research develops improved catalysts that convert atmospheric carbon dioxide into sustainable fuel. By analysing how molecular design affects reaction efficiency, selectivity, and durability, the work creates strategies to accelerate the chemical process and prevent breakdown. The findings support large-scale renewable energy storage and help integrate clean fuels into future energy systems.
