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.

Using solar energy to give new functions to a wide range of products
Crystalline silicon is currently the primary material for volume photovoltaic solar panel production on the global market. However, other technologies suitable for niche applications do exist. Copper indium gallium selenide (CIGS) and copper zinc tin sulfide (CZTS) solar cells can, for example, overcome certain challenges when integrating PV cells onto some types of materials. The advantage lies in the fact that CIGS and CZTS can be deposited in thin layers onto objects and materials—whether rigid or flexible—not originally designed to produce energy. The resulting integrated PV capabilities can make any object self-powering, adding value to the end product.At Liten, we have made inorganic thin-layer technologies for photovoltaic applications one of the institute’s key research areas, with the goal of developing solutions for:
Various Liten research projects are looking at thin-layer technologies at different stages of maturity. The earlier-stage research is generally conducted under EU research projects, while later-stage projects are usually completed in partnership with manufacturers on specific products for rapid go-to-market. The broad spectrum covered by Liten research—backed by our recognized know-how in materials—positions the institute to study thin-layer technologies in-depth, taking into account all the processes used in the fabrication and integration of solar cells.Our research covers the two crucial building blocks of thin-layer PV cell production: light-absorbing materials—mainly CIGS and CZTS—and transparent conducting oxides (TCOs). While thin-layer PV yields, at 12% to 20%, are lower than those of crystalline silicon, thin-layer cells do open the door to flexible, lightweight PV modules and the integration of PV capabilities onto different materials and objects, two advantages that make the technology particularly attractive.
