IPVF – Institut Photovoltaïque d’Île-de-France

Become an actor of the Energy Transition by joining a team driven by innovation and impact to address today’s most decisive challenges.

IPVF is one of Europe’s leading research, innovation and education organizations whose mission is to accelerate the energy transition through science and technology. Supported by the French State, IPVF is labelled Institute for Energy Transition (ITE).

Bringing together recognized industrial leaders (TotalEnergies, EDF, Air Liquide, Horiba and Riber) and world-renowned academic research teams (CNRS, Ecole Polytechnique), IPVF’ multidisciplinary and international teams conduct research dedicated to clean energy technologies (photovoltaics, green hydrogen, etc.). IPVF has built an ambitious scientific and technological research program, divided into 6 programs and 24 sub-projects, to achieve this objective.
These programs are based on a high-level experimental platform of 8,000 m², located in Paris-Saclay, and comprising more than 100 cutting-edge equipment worth €30M.

 

 

JOB CONTEXT

The intern will participate to the optimization and characterization of high efficiency tandem Silicon/Cu(In,Ga)Se2 solar cells where two solar cells are superimposed on each other via an interfacial layer with each cell absorbing a specific part of the solar spectrum to maximize overall efficiency.

The internship’s main goal will be to improve the chemical lithography process for high efficiency Cu(In,Ga)Se2 solar cells. The lithography process will enable efficient sub-cell separation of the solar cell stack for opto-electrical characterization. This cell separation technique will replace the mechanical scribing technique currently in use at IPVF.

The optimization of the lithography process and the material and opto-electronic characterizations of solar cells are all part of the internship work.

This work is a continuation of IPVF’s activities and the institute’s know-how in lithography processes and the fabrication of Cu(In,Ga)Se2 based solar cells.

 

 

MAIN MISSIONS 

The candidate will be involved in lithography process optimization as well as material and opto-electronic characterization of solar cells.

His missions will be as follows:
– Design and optimization of lithography process for Cu(In,Ga)Se2 solar cells deposited on various back contacts
-Solar cell material characterization techniques such as Raman spectroscopy, Scanning Electron Microscopy (SEM), X-ray diffraction, photoluminescence, etc.
– Opto-electronic measurements of solar cell performance, such as current-potential measurements in AM1.5 light or quantum efficiency measurements.
