Three internship opportunities are opened for 2023 in the Sunlit team: Multilayer epitaxial lift-off for low-cost III-V//Si tandem solar cells Multiscale characterization of photovoltaic materials New assessment of the efficiency limits in solar photovoltaics PhD positions on ultrathin solar cells … Continued
The thematic school on the Physics of Solar Cells: from basic principles to material science (PVSchool2022) was hosted by Les Houches School of Physics located in the French Alps, from 3-8 April 2022. The school was organized by Stéphane Collin … Continued
L’origine anthropique du réchauffement climatique ne fait plus de doute, et l’accord de Paris adopté en 2015 par la quasi-totalité des pays du monde a fixé l’objectif d’une augmentation moyenne de la température inférieure à 2°C. La transition énergétique est … Continued
In a series of two articles recently published in Phys. Rev. Applied, we show how cathodoluminescence mapping can be used to provide a contactless, quantitative assessment of active doping at the nanoscale. The method is applied to n-doped and p-doped … Continued
A postdoc position has been opened at IPVF to strengthen our projects on III-V//Si multijunction solar cells. The postdoc will work at IPVF and C2N in our team. IPVF and C2N are seeking a postdoctoral researcher to work on new … Continued
The IPVF Newsletter of June 2021 is out! This month, the editorial is proposed by Stéphane Collin. It is reproduced below. News from the IPVF III-V/c-Si tandem solar cell program. In the past years, solar photovoltaics (PV) became one of … Continued
The CNRS has just opened a permanent research engineer position at C2N in engineering sciences and scientific instrumentation. The research engineer will be responsible for the optical spectroscopy platform for characterization of materials at the nanometric and picosecond scales. Applications … Continued
A PhD position on new concepts for ultrathin solar cells is open at C2N. Short summary: Thickness reduction can be a key element in the quest for cheaper and more efficient solar cells. We have developed new strategies to trap … Continued
Le Monde, the reference French newspaper, in partnership with CNRS Le Journal, published today a video shot at C2N that highlights our results on ultrathin solar cells and their prospects for tomorrow’s photovoltaics. “Flexible solar cells that are a thousand … Continued
We have designed ohmic and reflective back contacts (RBC) for ultrathin CIGSe solar cells. They are made of multilayer stacks compatible with the direct deposition of CIGS at 500°C and above. Diffusion mechanisms and reactions at each interface are carefully … Continued
Congratulations to Dr. Thomas Bidaud for his successful thesis defense on January 8th, 2021! It was held simultaneously at C2N and by video-conference. The PhD dissertation and presentation were entitled: Characterization of nanomaterials by cathodoluminescence for photovoltaic applications. We were … Continued
Thickness reduction can be a key element in the quest for cheaper and more efficient solar cells. Making solar cells at least 10 times thinner than commercial ones would save material, reduce manufacturing costs, and enable new applications due to … Continued
After the great success of the first PV School on Physics of Solar Cells: from basics to nanoscience (25-30 March 2018) and the second PV School on Physics of Solar Cells: from basic principles to advanced characterization (1-6 March 2020) … Continued
Congratulations to Dr. Romaric de Lépinau for his successful thesis defense on June 12th, 2020! It was held simultaneously at IPVF and by video-conference. The PhD dissertation and presentation were entitled: GaAs-on-Si solar cells based on nanowire arrays grown by … Continued
The SUNLIT Team is working hard on ultrathin CIGS solar cells, in the framework of the ARCIGS-M H2020 european project, with the strong involvement of Louis Gouillart during his PhD work, and our postdoctoral researcher Joya Zeitouny. Our recent results … Continued
