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.”
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).
