Liten is a major European research institute and a driving force behind the development of the sustainable energy technologies of the future. The institute is spearheading the EU’s efforts to limit dependency on fossil fuels and reduce greenhouse gas emissions in three key areas: renewable energy, energy efficiency/storage and development of materials.
Our platforms, sophisticated tools for industry & the scientific/technical infrastructure/expertise to overcome technological hurdles
Liten's research teams work across a vast portfolio of renewable energy technologies. Cutting-edge photovoltaic technologies are developed at INES, the French National centre for solar research and R&D with Hydrogen and Biomass activities being managed from the LITEN's main site in Grenoble, Rhone-Alpes.

Concentrator photovoltaics: staying ahead of the market on a high-potential technology
Liten’s research in the field of concentrator photovoltaics (CPV) aims to very substantially increase PV system yields by developing optics capable of concentrating the sun’s rays onto very-high-conversion-yield PV cells. To further increase the intensity of the light captured, CPV modules are installed on trackers that follow the course of the sun. As they can only capture direct sunlight, these systems are intended mainly for use in high-sunlight regions of the world. CPV yields, currently at around 35%, are much higher than those of traditional PV solar panels, offering about 18% on average. However, the sticker price is also higher. This is due in part to the very low penetration of CPV in current production systems, currently representing just 1% of the total worldwide energy production capacity.We have been conducting CPV research since 2010, making advances that have garnered the attention of the entire CPV community. Our researchers bring knowledge from a variety of disciplines—thermics, optics, semiconductor physics, assembly processes, and energy management—and leverage Liten’s renowned expertise in power electronics for example, to improve UPS designs and maintain high yields across the CPV value chain. CPV conversion yields are increasing by around one percent per year, making the technology particularly attractive for certain operating conditions. And at Liten we are continuing to build on these promising developments. Our work with Germany’s Fraunhofer Institute and France-based Soitec has led to record yields of 46%, for example. And we continue to take part in international research programs set up to significantly improve today’s technology.
