Become an actor of the Energy Transition by joining a team driven by innovation and impact to address today’s most decisive challenges.
IPVF – Institut Photovoltaïque d’Île-de-France, is a global Research, Innovation and Education center, which mission is to accelerate energy transition through science & technology.
Gathering industrial PV leaders (EDF, Total, Air Liquide, Horiba and Riber) and world-renowned academic research teams (CNRS, Ecole Polytechnique), multi-disciplinary and international IPVF teams conduct research for clean energy technologies.
Supported by the French State, IPVF is labelled Institute for Energy Transition (ITE).
IPVF at a glance:
This topic is part of the research and development activities carried out within IPVF and the GeePs (Génie Electrique et Electronique de Paris) laboratory in the field of PV materials and devices. In particular, these studies are conducted at the micro/nano scale using atomic force microscopy (AFM) metrology. In this field we use the C-AFM (Conductive AFM) and KPFM (Kelvin probe microscopy) electrical extensions to study and explore the local properties of different technological building blocks involved in PV devices.

The candidate will directly report to the Deputy Programs Director of IPVF.
The PhD student will have the following missions:
1. Carry out a bibliography work on c-AFM and KPFM instrumentation, and in particular applied to the study of PV materials and devices. In parallel, he/she will be trained in the use of AFM, with a particular focus on data acquisition and processing. He/she will also participate in the implementation of the KPFM measurement in the time domain where the contact potential difference (CPD) will be measured under pulsed and/or frequency modulated illumination. Several signal processing approaches applied to the surface photovoltage (SPV) measurement will be studied in order to access the characteristic times or phase shifts with the idea to evaluate and map the minority carrier lifetime.
2. In a second phase, the student will apply its new expertise to study different technologies developed at IPVF:
The candidate will integrate a dynamic and talented team driven by innovation and results. The thesis will take place bewteen laboratories of IPVF and GeePs.
