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 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.
Enel Green Power and the CEA at INES are developing high efficiency bifacial photovoltaic panels. This technology, intended mainly for large-scale ground-mounted power plants, can gain even more energy-efficient, and not only thanks to the efficiency of cells and modules. The addition of an energy conversion system, as close as possible to the panel, makes it possible to reduce the impact of certain defects linked to the installation site and to increase the overall power of the plant.
The CEA at INES obtained flexible perovskite solar modules with a surface area of 11.6 cm2 and a power conversion efficiency of 18.9% (stabilized efficiency > 18.5%).
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.
