PhD student “Opto-electrical characterization and modelling of CIGS/perovskite based tandem solar cells”

About the function

IMOMEC (IMEC-Uhasselt) PV research teams are internationally recognized, thanks to its experts and world-class technology labs (Thin Film PV lab). It has a leading position on the development of semi-transparent perovskite (Pk)solar cells that are suitable for tandem applications.
Combining these solar cells with other thin film technologies like Cu(In,Ga)Se2(CIGS) will allow for a complete thin film tandem solar cells and its advantages for various light weight and flexible applications. At IMOMEC we are working on the development of these thin film tandem solar cells and investigate their long-term stability.
Together with the LCP group of Gent University we are working on advanced opto-electrical characterization and modelling of these tandem solar cells. A physics-based model is being developed at UGent to understand the opto-electrical properties of the complete tandem device. Our aim is to combine both experimental data and modelling to gain understanding in the long-term stability of CIGS/Pk tandem solar cells.
For this, there is a PhD position available on advanced opto-electrical characterization and modelling of these CIGS/Pk thin film tandem solar cells. This PhD position is funded by the Flemish Research Council (FWO) and the student will be affiliated with both UHasselt and UGent.

You will work in the Energy Laboratory of imec in Genk (EnergyVille) in the chalcogenide thin film-PV team of the imec department ‘imomec’ (associated imec laboratory at Hasselt University) where the devices will be fabricated and characterized and at UGent LCP group for more advanced opto-electrical characterization and modelling.
