What will you be doing?

We want to accelerate the market introduction of the Tandem Solar Energy technology. Tandem technology overcomes the current limit of photovoltaic modules namely the single-junction efficiency-limit by better using the light spectrum. Tandem enable efficiency potential up to 40% and beyond. The project deals with three main pillars:
  • Developing advanced tandem devices, bifacial and with different electrical configurations (4T, 2T) and their interconnections and encapsulation into modules.
  • Reliability of modules including accelerated aging test, outdoor test and fabrication of minimodules
  • Improved light management and energy yield calculation including prototyping and testing
The work consists in hands-on experience and data collection and analysis as well as modelling (optical) and validation.

What do we require of you?

  • The duration of this project should be ideally 12 months, preferably in the MSc phase of your study (mention this in your application)
  • A background in physics, chemistry, material science or electrical engineering
  • Interest in the energy transition
  • High motivation, with a curious nature and a taste for problem-solving
  • Ability to work autonomously within a small team and good social skills to get the information you need from the most knowledgeable people around you
  • Good communication (in English)
  • You need to be affiliated with a university for eligibility
