Do you want to do a PhD on the stability and reliability of perovskite tandems using indoor and outdoor stress tests? Apply now!

Job description

The National Dutch Growth Fund programme SolarNL “Circular integrated high-efficiency solar panels” targets to develop and industrialise three innovative PV technologies selected for their potential to be competitive in their respective markets alongside the incumbent mainstream PV: high-efficiency silicon heterojunction cells, flexible perovskite foils, and custom-integrated PV products for buildings and automotive.

Your job
Each of the corresponding programme lines contains comprehensive innovation activities connecting research, technology and product development, industrialisation and ramp-up to scale. The ‘design-for-circularity’ principle in each of the technologies and products is used in order to have the built-in potential for recycling and minimising the use of critical materials.

One of the three technologies will involve silicon/perovskite tandem structures. While perovskite cells and modules have reached over 25% efficiency for single junction devices and over 33% for tandem devices, these lab efficiencies need to be transferred to large-area commercial processes while at the same time demonstrating their reliability. Perovskite device stability is affected by multiple parameters and is not fully understood yet. This includes light (UV/vis) induced degradation, temperature induced degradation, and degradation due to oxygen/humidity as external stressors. Also, ion migration is denoted as a cause for degradation. An intriguing phenomenon is self-healing, which would repair light-degradation during the night, when perovskite devices are monitored outdoors.

In this project, the indoor and outdoor performance of new module architectures will be investigated, i.e., tandem a-Si:H/perovskite, triple a-Si:H/nc-Si:H/perovskite, and tandem high bandgap perovskite/nc-Si:H. This will be done in close collaboration with other academic and industrial partners in the SolarNL programme. This PhD project should lead to increased insight in the stability of new proposed module architectures by degradation analysis and established specific energy yields in kWh/kWp in outdoor conditions (energy rating).

Your tasks include:
  • designing and performing indoor and outdoor tests to investigate tandem stability;
  • correlation of indoor and outdoor results to establish transferability of indoor results to outdoor conditions;
  • investigation of degradation and self-healing in relation to the actual module architectures.

You will work in a highly interdisciplinary, gender-balanced, and internationally oriented research with chemists, physicists, and engineers from across Europe. You will be part of a large group of starting PhD candidates all active in the SolarNL programme.
