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.
In research conducted for the EU m2M-grid project, CEA-Liten, a CEA Tech institute, developed advanced microgrid coordination tools that were successfully tested on a real grid operated by electric utility SOREA.
Towards a new space solar generator architecture for a European high power solution. Space missions require always more solar electric power, typically more than 25kW, to power the electric propulsion of satellites and other functions such as broadband telecommunications. The available volume in satellite launch rockets is limited and does not allow the number and size of conventional rigid solar panels on board to be increased.
Since the entry of the private companies on the space market, satellites and their manufacturing processes have been subject to major changes. The space applications provide a vast field of opportunities for the development of IoT, communications, terrestrial, air and maritime navigation and positioning systems, as well as remote medicine.
While Europe and certain Asian countries are announcing ambitious hydrogen plans, Symbio – a hydrogen fuel cell systems supplier and subsidiary of Michelin and Faurecia – and CEA, committed to the research and development of hydrogen technologies, are strengthening their historic relationship by signing a framework collaboration agreement. Aim: to accelerate the industrialisation of competitive hydrogen fuel cell systems on a world scale for the energy transition of transport.
In research conducted for the EU INTEGRAL project, Liten, a CEA Tech institute, helped scale up second-generation thermoelectric materials and validation-test their use on functional thermoelectric generator demonstrators.
Liten, a CEA-Tech institute, is testing a diphasic-fluid-based cooling system for high-power lithium-ion batteries in research for the Carnot Network’s REDBAT project.
Ventilairsec partnered with Liten, a CEA Tech institute, on a residential HVAC solution that takes care of air quality and heating.
When it comes to functionally integrating photovoltaic modules into buildings, it is vital to address architectural concerns. Liten, a CEA Tech institute recently evaluated techniques to improve the appearance of building-integrated photovoltaic solutions.
Nitrogen oxides, produced mainly when diesel fuel is burned, are harmful pollutants. Liten, a CEA Tech institute, recently modified automotive cabin air filters to effectively filter out nitrogen oxides at ambient temperature, improving air quality for drivers and passengers.
The digital publication Open Access Government published an article about the EU project SUPREME. Thierry Baffie, research engineer at the CEA-Liten and coordinator of the EU project SUPREME, highlights achievements in sustainable powder metallurgy
Microelectronics manufacturers can now access exceptional nanoparticle detection and characterization resources to test their gas and liquid effluents.
The European large-scale research initiative BATTERY 2030+ presents the long-term research roadmap that outlines the actions needed to invent the sustainable batteries of the future.
A first-ever proof-of-concept of a 1 kW PEMFC stack made with printed components was recently completed. The technology is implemented using continuous processes, which reduces costs. However, it also promises to boost power densities.
A new computer-aided design tool will make battery packs safer by measuring the impact of dimensioning changes on the behavior of the battery packs. Specifically, the tool improves the evaluation of thermal runaway risk.
