Renewable energy and energy efficiency
The vast majority of CEA Tech institute Liten’s photovoltaic R&D focuses on crystalline silicon, the material used to make PV cells. The technology currently has a market share of 90 % to 95 %.
The institute’s research addresses the entire value chain, from the raw material to the cell and module. The goal is twofold: bring manufacturing costs down and boost PV cell and overall system yields. One of Liten’s flagship research areas is monolike silicon production; this material offers the yields of monocrystalline silicon and the cost savings of polycrystalline silicon.
From module encapsulation with lightweight, flexible, and recyclable materials through to the integration of smart self-troubleshooting and safety capabilities, Liten’s know-how spans a broad range of PV-related issues.
Liten is also working on organic PV cells for niche markets.
ALL TECHNOLOGY PLATFORMS
RTE and the CEA have just completed an 8-month experiment on the charging infrastructure for electric vehicles at the CEA centre in Cadarache. The aim was to link the charging stations to a solar power plant and an intelligent management and control system in order to significantly increase the share of solar energy in electric mobility.
CEA-Liten, a CEA Tech institute, partnered with IBS on research for the ISICELL project to develop a technology for doping photovoltaic cells that is ready to scale up for manufacturing. The technology, which leverages an innovative method, simplifies PV cell manufacturing processes and improves performance.
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 INES team has recently achieved a new heterojunction 72 cell module record performance at 410W in collaboration with Meyer Burger.
Perovskite-based photovoltaic systems were recently created on larger surfaces than the current laboratory prototypes, enabling the technology to be scaled up from individual cells to modules.
How to collaborate with CEA Tech teams ?
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.
