Research Associate Investigating Nano- and Micro-scale Loss Mechanisms in Perovskite Solar Cells

University of Cambridge - Cavendish Laboratory, Department of Physics

Fixed-term: The funds for this post are available for 24 months in the first instance but the post may be extended up to a further 12 months.

Applications are invited for a Post-Doctoral Research Associate to work on the microscopic characterisation of halide perovskite optoelectronics at the Cavendish Laboratory (University of Cambridge). This will combine microscale spectroscopy with related electronic, chemical and materials microscopy characterisation approaches to elucidate fundamental new insight into these semiconductors and guide elimination of the power losses.

The successful candidate will join the research group of Sam Stranks ( The group’s research focuses on the optical and electronic properties of emerging semiconductors with particular interests in low-cost, transformative electronics applications including photovoltaics and lighting. The group uses optical spectroscopy tools on a range of length and time scales, in conjunction with other material characterisation tools, to unveil loss mechanisms, discover new semiconducting materials, guide innovative device designs, and push device performance to the limits. The team is part of the Optoelectronics Group (, one of the world's leading academic groups in the field of organic and hybrid electronics.

We are looking for a highly motivated and enthusiastic candidate with a PhD in Physics, Chemistry, Materials Science or a related area. A proven track record of scientific publication and presentation at international conferences is essential. Experience in microscale characterisation techniques is essential, including but not limited to, confocal luminescence techniques (especially time-resolved), electron microscopy including cathodoluminescence, atomic force microscopy, Raman microscopy and secondary ion mass spectrometry. Direct experience working with halide perovskites is highly desired. Experience with building time-resolved optical spectroscopic equipment is also highly desired. The development of independent research projects and research student supervision will also be expected, and existing evidence of the ability to do so would be a plus. The ideal candidate would also assist with laboratory design and setup, and interact with a wide international network of collaborators.

Where the successful applicant does not yet have a PhD, he/she will normally be under-appointed as a Research Assistant in a Research Associate post (on the understanding that he/she will be appointed as a Research Associate upon successful completion of his/her PhD).

Applications will be rapidly reviewed after the closing date and interviews conducted shortly thereafter. The candidate would ideally start as soon as possible after 1st May but there will be some flexibility on the starting date. The role is funded by the EPSRC New Investigator Grant entitled ‘The Origin of Non-Radiative Losses in Metal Halide Perovskites’, a new programme investigating nano- and micro-scale loss mechanisms in perovskite solar cells and LEDs.

Informal inquires can be addressed via email to Sam Stranks (
