Swansea University

Swansea University is offering a fully funded PhD studentship in Advancing Sustainable Solar Solutions to Transform Global Energy Access, aligned with the UNESCO Chair in Sustainable Energy Technologies and the REACH-PSM project. This opportunity is ideal for candidates passionate about renewable energy, sustainability, and materials engineering, with a focus on developing innovative perovskite solar modules for deployment in underserved regions, particularly in Africa. The project aims to accelerate the development of printable perovskite photovoltaics by focusing on sustainable materials, photochemical characterization, and lifecycle analysis. Students will work on optimizing materials for cost-effectiveness, efficiency, and adaptability to diverse environments, while also assessing environmental impacts and developing recycling processes for second-generation products. The research is highly interdisciplinary, integrating materials science, chemistry, environmental science, and physics, and is supported by a vibrant team of experts including Prof. Matthew Davies, Dr. Sarah-Jane Dunlop-Potts, and Prof. Trystan Watson. Facilities at Swansea University’s Bay Campus provide access to state-of-the-art research equipment and a collaborative environment with global UNESCO Chair partners and REACH-PSM collaborators. The project supports the United Nations’ Sustainable Development Goals by fostering equitable and sustainable energy access through community-driven approaches. Funding: The studentship covers full tuition fees and provides an annual stipend at the UKRI rate (£20,780 for 2025/26), plus up to £1,000 per year for research expenses. International students are not charged the fee difference between UK and international rates. Funding is for 3 years. Eligibility: Applicants must have at least a 2.1 undergraduate degree (or equivalent) in Engineering or a relevant science discipline. English language proficiency (IELTS 6.5 overall, minimum 5.5 in each component or equivalent) is required. Up to 30% of the cohort can be international students. Some applicants may need ATAS clearance. Required documents include CV, degree certificates and transcripts, cover letter with personal statement, one reference, evidence of English proficiency, visa (if applicable), and confirmation of EDI form submission. Application Process: Apply online via Swansea University, entering RS934 in the relevant sections and uploading all required documents. For questions, contact Prof Matthew Davies at [email protected]. The deadline for applications is 2 February 2026, with a project start date of 1 April 2026. Keywords: Materials Engineering, Sustainable Energy, Solar Solutions, Photovoltaics, Perovskites, Renewable Energy, International Development, Sustainability, Circular Economy, Energy Access, Africa, Lifecycle Analysis.

This fully funded PhD studentship at Swansea University offers an outstanding opportunity to advance sustainable solar solutions and transform global energy access, particularly in underserved regions. The project is embedded within Swansea University’s UNESCO Chair in Sustainable Energy Technologies and the REACH-PSM initiative, focusing on community-driven development of perovskite solar module manufacturing. These efforts align with the United Nations’ Sustainable Development Goals, aiming to foster equitable and sustainable energy access through innovative research and global partnerships. As a PhD student, you will accelerate the development of printable perovskite photovoltaics for deployment in Africa, with a strong emphasis on sustainable materials. The research will involve advanced photochemical characterisation to understand device uniformity, morphology, performance, and stability. You will optimise materials to be cost-effective, efficient, and adaptable to diverse environmental conditions, and assess their environmental impacts using lifecycle analysis. The project also includes developing processes for reusing and recycling key materials, contributing to circular economy principles and the creation of second-generation solar products. Collaboration is central to this studentship. You will work closely with UNESCO Chair partners, REACH-PSM collaborators, and local communities to ensure that technological advancements are socially impactful and suitable for real-world applications. The research environment at Swansea University’s Bay Campus is internationally renowned, offering state-of-the-art facilities and a vibrant, multidisciplinary team. Supervisors Professor Matthew Davies and Professor Trystan Watson, along with other leading experts, will provide guidance and support throughout your studies. Funding for this position covers the full cost of tuition fees and provides an annual stipend at the UKRI rate (£20,780 for 2025/26), with no fee difference for international students. The studentship is available for three years and is open to both UK and international applicants, subject to cohort quotas. Applicants must hold a 2.1 undergraduate degree (or non-UK equivalent) in Engineering or a relevant science discipline, and meet English language requirements (IELTS 6.5 overall, minimum 5.5 in each component). Some applicants may require ATAS clearance, but this is not necessary for the initial application. To apply, submit your application via the Swansea University portal before the deadline of 2 February 2026. Ensure you provide all required documentation and check country-specific entry requirements if applying from outside the UK. Successful candidates will be informed about ATAS clearance procedures if applicable. This studentship is ideal for those passionate about renewable energy, sustainability, and making a real-world impact through research and innovation.

Mesoscopic carbon‐based perovskite solar cells (C‐PSCs) have the potential to be manufactured at an industrial scale by utilizing screen‐printing, a simple, affordable, and commercially mature process. As such, many recent publications have focused on enhancing performance through modifying cell architecture and perovskite chemistries. This work examines how ink rheology can be tuned to optimize cell performance through reducing the occurrence of common print defects to create higher quality m‐TiO 2 films. Inks with different solvent dilutions and rheological profiles are assessed using high‐speed imaging through the screen‐printing visualization (SPV) technique, to investigate the impact of the viscosity and elasticity on ink separation mechanisms. The resultant film quality and its influence on device performances are then assessed. Ink separation lengths are minimized, and the formation of filaments ceases during printing, leading to improved TiO 2 film topography and homogenous infiltration of the perovskite precursor. Consequently, PCE is improved by over 10% of the original efficiency in cells and 224 cm 2 active area modules due to enhanced V oc and FF. These results not only provide key insights into tailoring ink rheology, to achieve improved print homogeneity and higher performing cells, but also aid further work on enhancing the performance of other screen‐printed functional films.
