This PhD project at the University of Southampton is supervised by Dr Pier Sazio, Dr Peter Horak, and Prof Mike Zervas. The research focuses on repurposing photonic fibre technologies, which are foundational to global telecommunications, for innovative renewable energy applications. The project aims to explore how these advanced optical fibres can be utilized in solar energy generation and in developing low-cost energy storage solutions. Students will engage in interdisciplinary research at the intersection of photonics, energy conversion, and sustainable technology, contributing to the development of new methods for harnessing and storing renewable energy. The supervisory team brings expertise in photonics and fibre optics, providing a strong foundation for research and professional development. The University of Southampton offers a vibrant research environment and access to state-of-the-art facilities. Funding details and specific entry requirements are not provided in the current description. Interested candidates are encouraged to seek further information from the university or the supervisors.
