Recent developments at Liten, a CEA Tech institute, could lay the foundations for PV modules with advanced BIST (built-in self-test) capabilities. Faults will be detected and identified in record time, without bringing PV production to a halt.
Liten, a CEA Tech institute, recently produced a small run of PV modules on its dedicated platform. The project was completed in partnership with Mondragon Assembly. And the modules passed IEC 61215 certification testing without a hitch!
CEA Tech wishes to challenge the existing record for the highest quantity of electricity generated by bicycle power (the current record being held by Emanuel Fernando Valdez Avila in Mexico – 495.4 watt hours). In order to try to beat this record CEA Tech’s LETI and LITEN research institutes will use a turbo trainer fitted with a high performance alternator, based on patented CEA Tech technology, at the heart of which lies an extremely powerful bespoke magnet.
Liten's annual report for 2014 is now available.
Lithium-sulfur batteries are ideal candidates for applications requiring high specific energy, but they do have limitations. Thanks to some clever tricks, researchers at Liten, a CEA Tech institute, have successfully overcome the most serious of them.
The Organic/Hybrid Printed Photovoltaic field is growing and is reaching the production scale where development of large area processes is needed. To this aim, researchers from CEA-Liten, based at INES, France, have developed a flexible organic photovoltaic module manufactured entirely by inkjet printing processes that demonstrates power conversion efficiency above 4% for high value, custom-made, solar devices.
By listening to the sounds emitted by batteries, researchers have been able to improve battery charge cycles, enhance functional safety, and control post-manufacturing quality without altering the batteries.
CEA Liten has validated a hydrogen production system using high-temperature steam electrolysis and offering outstanding performance.
