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.
CEA at INES keep improving Passivated contact solar cells with the platform developed by SEMCO Smartech for boron diffusion and LPCVD deposition of polysilicon on oxide.
CEA at INES and Enel Green Power have reached this summer a heterojunction solar cell record efficiency of 25.0% active area (213 cm²) on M2 wafer on CEA’s industrial pilot line.
CEA has been working for several years on the development of silicon heterojunction cells. A characterization method based on the analysis of point defects on silicon wafers generated during all wafer handling has been developped, based on electroluminescence and/or photoluminescence image analysis.
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.
