2 PhD Student Positions in Advanced Characterization of Semiconductors for Photovoltaic Applications

Reference : MRT-2019-PACE-2

Type: PhD Student
Contract type: Fixed term contract
Duration: Up to 4 years
Place: Belval



PACE (https://pace.uni.lu) is a competitive PhD training program for a total of 8 PhD candidates, supported by the research funding scheme PRIDE of the Luxembourg National Research Fund (FNR). The PACE doctoral training unit provides structured PhD training in advanced photovoltaic concepts for building highly efficient next generation solar cells. Our aim is to start all 8 students together, to form a cohort.

The PACE program involves a close collaboration between the University of Luxembourg and the Luxembourg Institute of Science and Technology. Industrial visits and secondments are foreseen. The PACE program includes transferable skill training, support in career development, scientific lectures by international speakers and annual PhD retreats. The PhD candidates will be enrolled at the Doctoral School of Science and Engineering at the University of Luxembourg.

The research program focusses on tandem and micro solar cells, with 5 positions relating directly to these concepts. 2 positions are for advanced characterization of the material synthesized in the making of the solar cells. 1 further position is dedicated to understanding the defect physics of the used semiconductors.




Candidate F will conduct correlative optical and electrical characterization of different thin film solar cell technologies on the micrometer scale in order to deeply understand the materials properties. The tasks of this candidate include: Hyperspectral time resolved photoluminescence imaging of CIGSe, hybrid perovskites and photo-ferroelectric materials and Kelvin Probe Force Microscopy in inert gas and ultra-high vacuum on selected samples to correlate the optical properties to the electrical properties on the micrometer scale. Email alex.redinger@uni.lu for more information.

Candidate G: The AINA group at LIST has been developing a Secondary Ion Mass Spectrometry (SIMS) add-on system for the Helium Ion Microscope (HIM) and for a Transmission Electron Microscope (TEM), allowing the advantages of high spatial resolution with high sensitivity chemical information to be combined. The candidate will use these novel multi-modal analytical instruments (HIM-SIMS and TEM-SIMS) to develop correlative nano-scale methodologies and apply them to photovoltaic samples. The PhD candidate will acquire highly-valued skills in advanced characterization techniques (TEM, HIM, SIMS) applicable in a number of fields in materials science and beyond. Email tom.wirtz@list.lu for more information.
