CEA-INES is looking for a post-doc to work on 2D simulation of perovskites/silicon heterojunction tandem solar cells. The candidate will have the responsibility to develop a model of the PK/SHJ tandem cell on the TCAD simulation package Silvaco. A realistic description of the materials will be implemented, based on in-house characterization of actual layers used (potentially performed during the post-doc), or based on literature. Then the focus will be set on the adjustment of the interface between the two sub-cells (so-called recombination junction, or tunnel junction). This model will afterwards be used to improve our understanding of the tandem cell working principle. In particular, inhomogeneity in layer properties, defects and there influence on cell efficiency will be investigated and brought face to face with experimental results. Finally, strategies to mitigate the influence of these defects will be defined to help the development teams to increase the device efficiency on large areas. For this post-doc position, the candidate needs solid background in semi-conductor physics, as well as previous record in working with simulation tools. He/She will need strong organization skills, and be willing to conduct theoretical work. The results will be published in peer-reviewed journals, as well as in conferences.
