Le Monde and CNRS Le Journal: Ultrathin solar cells for tomorrow’s photovoltaics

posted in: News | 0

Le Monde, the reference French newspaper, in partnership with CNRS Le Journal, published today a video shot at C2N that highlights our results on ultrathin solar cells and their prospects for tomorrow’s photovoltaics.

“Flexible solar cells that are a thousand times thinner than commercial silicon cells with the same efficiency: this is the feat of two CNRS researchers who have developed a trap to “capture” light.”

Ultrathin solar cells for tomorrow’s photovoltaics

This work was carried out at the Centre de Nanosciences et de Nanostructures (C2N), with the support of the Institut Photovoltaïque d’Ile-de-France (IPVF), and in close collaboration with German Fraunhofer Institute for Solar Energy Systems (ISE) and the LCMCP (Sorbonne Université / CNRS / Collège de France).
