Research Fellow in PV Systems

We are recruiting a Research Fellow to study the temperature-dependent performance of photovoltaic modules in the field. The post offers access to a unique outdoor PV testing facility at the University of Southampton.

The successful candidate will join the EPSRC-funded project "TACOS-PV: Temperature Analysis and Characterisation in Operational Solar PhotoVoltaics", a collaboration between the Universities of Oxford and Southampton and the National Physical Laboratory (NPL). Temperature effects are the largest source of energy loss in PV systems, yet current models were not developed for today's high-efficiency technologies. TACOS-PV will deliver new measurement methods and models for advanced PV, including TOPCon, heterojunction, tandem and bifacial modules. Industrial and international partners include Lightsource BP, RINA, PV Lighthouse, QEERI, UNSW, Oxford PV and NREL.

The successful candidate will lead a year-long outdoor measurement campaign across multiple PV technologies. Responsibilities include:

- Developing high-precision in-situ module temperature measurement
- Developing high time-resolution I-V tracing to extract temperature coefficients in the field
- Using spectral irradiance data to improve ambient-to-cell temperature and energy yield models

The candidate will have a strong grounding in photovoltaic systems and a track record of journal publications. Essential experience includes spectroradiometry and instrumentation for irradiance and electrical power measurements, together with strong experimental and data analysis skills. Experience of outdoor PV testing, temperature metrology, and energy yield modelling is advantageous.

This post is suitable for a candidate with a PhD or equivalent professional qualifications and experience in Electronics and Electrical Engineering or Physics. The post is available to start from December 2026 and is a 24-month fixed-term appointment at 0.57 FTE.
