This PhD opportunity is part of the Centre for Doctoral Training in Green Industrial Futures (CDT-GIF), hosted at Imperial College London. The project focuses on developing advanced photovoltaic-electrocatalytic integrated devices for solar chemical production, aiming to harness solar energy to generate valuable chemicals such as hydrogen and carbon products from small molecules like carbon dioxide and water.

Research will center on the design and fabrication of photoelectrochemical (PEC) cells that integrate high-performance photovoltaic absorbers—halide perovskites or organic bulk heterojunctions—with innovative catalysts. These materials offer exceptional optoelectronic properties but face stability challenges in aqueous environments, which are critical for solar fuel production. The student will investigate protective strategies using carbon allotropes and electrochemically stable metal layers to enhance both device stability and catalytic efficiency.

Key objectives include aligning device architecture and reaction pathways to mitigate degradation, reduce voltage losses, and improve long-term performance. The project will involve experimental synthesis, advanced characterization techniques (including various microscopies and spectroscopies), and performance testing under simulated sunlight. Students will also gain experience in integrating their research within industrial systems, identifying barriers and opportunities for achieving net zero emissions.

The PhD will be conducted in the Applied Energy Materials labs at Imperial College's South Kensington campus, under the supervision of Professor Paul Fennell and Dr. Salvador Eslava. The CDT-GIF programme offers a comprehensive four-year training experience, including residential taught courses at partner universities, international opportunities, work placements with industrial partners, and a bespoke net-zero leadership programme. Students will receive expert training in life cycle analysis, technoeconomics, business models, policy and regulation, public engagement, and plant operation.

Funding covers full UK tuition fees, a tax-free stipend (£20,780 for 2025/2026 plus approximately £2,000 London weighting), and a budget for travel and consumables. Applicants should hold a First-class or 2:1 MEng or MSc with merit (over 60%) in Chemical Engineering, Process Engineering, Chemistry, Materials Science, Geoscience, or a related discipline. Candidates with a relevant MA for socio-politico-economic topics or a First-class BSc/BEng (Hons) with significant industry/research experience may also be considered. All applicants must meet Imperial College London's entry requirements.

Applications are accepted year-round. For further details and to apply, visit the CDT Green Industrial Futures website or contact [email protected].
