Liten research on the INES (France's solar energy research institute) campus covers the entire PV component value chain, from material and cell to module and system. With a focus on silicon technology, Liten is addressing not only conversion yields, but also cost and lifespan, which are vital inputs into the Levelized Cost of Energy (LCOE). Liten has obtained state-of-the-art performance on
industrial-scale equipment, making it one of the world's leading centers for high-efficiency PV research. Currently, the goal is to reach 25% on silicon and, ultimately, 30% with tandem technologies.
Liten's research focuses mainly on:
Photovoltaic cells: The three pillars of development
Liten's research and development strategy is at the center of a complete ecosystem that includes equipment and component manufacturers, integrators, and operators.
The CEA at INES has produced a demonstrator panel with a carbon footprint of 317 kgCO2eq/kWp. This achievement, which incorporates several innovations, makes our laboratories among the leaders in Europe.
The CEA at INES, in collaboration with ENEL Green Power and its subsidiary 3SUN in Catania, are developing the two-terminal perovskite-silicon tandem technology with the aim of achieving high efficiency devices that can be industrialized as soon as possible. A new record has just been obtained with a PIN-architecture cell at a conversion efficiency of 25.8% over 9 cm² with shading correction.
The large-scale deployment of solar energy and the sustainability of the photovoltaic industry require further improvements in the environmental footprint of technologies. One of the challenges is to reduce the use of certain materials such as silver, which is deposited during the metallization stage of the cells, with a positive effect on the competitiveness of the industry.
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.
