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
A power-component test bench with photovoltaic-type aging capabilities was developed under the Memphis project.
The REACSOL solar reactor developed by Liten, a CEA Tech institute, was successfully used for high-temperature biomass gasification in tests carried out in conjunction with lab CNRS-PROMES. The results of the tests—gasification of wood-based biomass continuously fed into the reactor with concentrated solar energy as the heat source—were encouraging.
The Nanocharacterization platform’s two Titan transmission electron microscopes recently received some major upgrades. They now provide more than just images, delivering detailed information on the chemistry of the materials being analyzed.
For the first time ever, 60 bifacial photovoltaic modules were manufactured on the semi-automated assembly line at the Modules Platform operated by Liten, a CEA Tech institute.
Liten, a CEA Tech institute, has successfully reduced monolike silicon solar cell performance losses due to light-induced degradation to under 2%.
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.
