Reportage France Culture for « La Méthode Scientifique » at the IPVF’s ALD laboratory


How does photovoltaic energy work and what are the principles on which its production is based? What are the advantages and limitations of this technology? How is research being mobilized to improve photovoltaic performance?

A discussion broadcast on February 10, 2021 in which Nathanaelle Schneider, a chemical researcher specializing in the design and development of new materials for photovoltaics at the Institut photovoltaïque d’Île-de-France, who won the CNRS 2020 Bronze Medal, participates. She presents, from minute 37, the principles and promises carried by the Atomic Layer Deposition (ALD) for solar applications.

« Imagining new molecules, synthesizing them and using all possible tools to understand their behavior and properties fascinates me. I started by studying them in solution during my PhD, and then I became interested in their interactions with a surface. This led me to the synthesis of « thin-film » materials, i.e., a few tens of nanometers from molecular precursors. My research studies the behavior of these molecules during the growth of the material and also the properties they give it. My goal is to develop new high-performance materials adapted to the solar cells of the future. In addition to the knowledge and experience acquired, exchanges between scientists and open-mindedness are essential to carry out innovative research: this is one of the most stimulating aspects of my job! « Nathanaelle Schneider
