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.
“Radically improving energy efficiency will reduce the need for investment in energy infrastructure, cut fuel costs, increase competitiveness, lessen exposure to fuel price volatility, increase energy affordability for low-income households and cut local and global pollutants improving consumer welfare” Source OECD Energy report, 2014

The photovoltaic community is enthusiastic talking about the industrialization of this new structure that integrates a passivated contact on the rear side of the cell. The result obtained by CEA-Liten in collaboration with SEMCO Smartech at INES, the French National Institute for Solar Energy is a first step (stepping-stone) for the industrial demonstration of this technology towards the 26% efficiency already reached on small surface.
CEA-Liten and SEMCO Smartech are developing equipment and processes to produce passivated contact PV cells at industrial scale: on large surface, using high throughput screen-printing.
HORTUS® the new platform developed by SEMCO for boron diffusion and LPCVD deposition of Polysilicon on ultra-thin silicon oxide films already demonstrated its ability to produce passivated contacts with passivation levels among the best of the state of the art (i-Voc 745 mV).
M2 industrial solar cell made with passivated contacts on the HORTUS® tool was obtained during summer. It was measured internally in CEA's lab at 22.8% efficiency.
This result should be quickly outperformed by CEA and SEMCO who have already identified the way to improve the performances over 23% within this year and 25% mid-term.
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.
