Posted on: November 14, 2025

We are looking for a highly motivated postdoctoral researcher to develop next-generation field inspection and diagnostic tools for photovoltaic (PV) systems based on luminescence imaging, infrared thermography and image-based performance modelling. You will join the Solar Photovoltaics Systems Team at DTU Electro, an internationally recognized research environment focusing on reliability, performance, and digitalization of solar energy systems.

Responsibilities and qualifications
As a postdoctoral researcher, you will play a key role in advancing DTU Electro’s research by bridging laboratory imaging techniques on PV modules to large scale field inspections. You will contribute to the development of daylight electroluminescence and photoluminescence inspections together with data-driven frameworks to support predictive maintenance assessment of PV plants.

Your main responsibilities will include:

  • Developing and optimizing daylight luminescence imaging techniques for field inspection of crystalline-silicon PV modules.
  • Designing and conducting experimental campaigns, including drone- and gantry-based luminescence measurements under real operating conditions.
  • Integrating image analysis, modelling and machine learning to improve defect detection, classification and power loss simulations.
  • Benchmarking field-acquired images with laboratory measurements. 
  • Publishing results in leading journals and contribute to international collaboration projects with academic and industrial partners.

We are looking for a candidate who meets the following qualifications:

  • Strong experience in electroluminescence and photoluminescence imaging, preferably daylight and field-based methods. 
  • Proven skills in data analysis, image processing and machine learning. Experience with PV performance modelling, power loss simulations from luminescence images. 
  • Experience PV performance modelling, infrared thermography or field measurement systems is highly advantageous. 

You are expected to work independently and collaboratively, communicate results clearly in English, and contribute actively to team development.

As a formal qualification, you must hold a PhD degree (or equivalent) in Photovoltaics or a related field.
