RESOURCE FACILITY

PROVIDE STATE-OF-THE-ART EQUIPMENT
The IPVF owns and operates a fleet of more than 70 high-tech equipment.
These equipments allow among other things to:

  • Develop materials with photoelectric properties. Many physical and/or chemical paths are available, including deposition, growth, spraying, evaporation and chemical synthesis techniques.
  • Assemble these materials into photovoltaic cells. This involves modifying the properties of materials as required, and adding functional layers (anti-reflection, protective barriers, light trapping, collection of electrical charges, etc.)
  • Characterize these materials and cells. It is a question here of subjecting them to a whole battery of tests (optical, electrical, chemical, morphological…) in order to measure their characteristics, and to better understand the physical phenomena involved, at a scale ranging from cm (10-2m) to nm (10-9m), this in a logic of permanent improvement.

These experimental equipments are complemented by important and varied modelling tools. Modelling makes it possible to simulate the behaviour of materials or cells from the atomic scale (ab-initio) to the macroscopic scale.

The trio of elaboration, characterization and modelling thus makes it possible to accelerate the development of high-performance photovoltaic devices.
