Job Description

Applications are invited for a Postdoctoral Research Assistant with expertise in the synthesis and characterisation of novel semiconductor materials.

The position is available for a fixed term until 30 September 2028.

This project is associated with an exciting new EPSRC/UKRI-funded Programme Grant

entitled "Advanced Device Concepts for Next-Generation Photovoltaics."

This collaborative project between Oxford Physics, Materials and Chemistry and Liverpool Chemistry brings together expertise in photovoltaic materials synthesis and device fabrication, advanced characterisation and modelling. The ambition for this project is to carry out multidisciplinary research, via inter-linked work streams, that will explore and conceive four new photovoltaic device concepts and paradigms, enabling the next major step-change in photovoltaic efficiency. New devices architectures, concentrator PV, quantum cutting, hot-carrier collection and photon transport, will be explored and enabled by absorber materials based on metal-halide perovskites, silicon, and novel low-band-gap chalcogenide-halide semiconductors, supported by fundamental experimental characterisation and materials modelling. Addressing these future advanced concepts through a holistic approach will enable key scientific discoveries and important major technical advances enabling the next generation of PV technologies for beyond 2030.

This role will utilise both solution- and vapour-based materials synthesis techniques for novel semiconductor materials and doping of halide perovskites. It will also involve significant materials characterisation using techniques such as X-ray diffraction, and spectroscopic analysis using NMR and photoluminescence. The post holder will make use of the extensive materials and device fabrication and characterisation facilities in Oxford Physics and make use of the National Thin Film Cluster for Vapour Deposition of Advanced Functional Materials. The post-holder will regularly interact and collaborate with theorists working on materials and device modelling, spectroscopists, materials scientists and chemists also working on the project to ensure a continuous and productive feedback loop between materials design and device fabrication.

Applicants should possess or be close to obtaining a PhD in physics, chemistry, materials science or engineering. They should be highly versed in materials synthesis and characterisation, and thin-film deposition techniques. Knowledge of semiconductor physics and a track record of working with next-generation novel materials for light-harvesting is essential.

Applicants should be highly motivated and have excellent skills in working collaboratively as part of a team. A good track record of high-quality publications is essential. Having the ability to direct your own research and interpret your results independently is a must.

The University of Oxford and the Department of Physics offer an inclusive and diverse environment and workplace. We strongly encourage applications from all backgrounds and genders to apply.

For further information please contact Prof. Nakita K. Noel (nakita.noel@physics.ox.ac.uk)/Prof. Henry J. Snaith (henry.snaith@physics.ox.ac.uk).

Only applications received before midday 7 November 2025 can be considered

. You will be required to upload a brief statement of research interests, CV and details of two referees as part of your online application.
