IRIG researchers report photochromic dye-sensitized solar cells based on photo-sensitizing molecules allowing change in colour and self-adjustable light transmittance when irradiated. Those cells present a power conversion efficiency up to 4.17%, a reversible colouration–decolouration process, and are stable over 50 days.
CEA is a French government-funded technological research organisation in four main areas: low-carbon energies, defense and security, information technologies and health technologies. A prominent player in the European Research Area, it is involved in setting up collaborative projects with many partners around the world.
