Advanced crystalline silicon photovoltaics

Advanced crystalline silicon photovoltaics Researchers at the LPICM are currently leading or participating in multiple projects in crystalline silicon photovoltaic (PV) technology: ANR Industrial Chair project PISTOL (with TotalEnergies) on IBC HJT solar cells, IPVF programs II and III on tandem solar cells, EU Solar Eranet project CUSTCO. The work in the area merges our […]

Insight into the formation and stability of solid electrolyte interphase (SEI) for nanostructured silicon-based anode electrodes used in Li-ion batteries

Silicon-based anode fabrication with nano-scale structuration improves the energy density and life cycle of Li-ion batteries. As-synthesized silicon (Si) nanowires (NWs) or nanoparticles (NPs) directly on the current collector represent a credible alternative to conventional graphite anode. However, the operating potentials of these electrodes are below the electrochemical stability window of all electrolytes used in […]

Plasmonic Nanomaterials and Metal Organic Frameworks for Air Sensing

We are developing optical chemical sensors combining two types of promising nanomaterials: plasmonic metallic nanoparticles, to benefit of their capacity to enhance local electric fields; and metallic organic frameworks (MOFs), porous materials tailored to capture specific molecules. This ambitious project, sponsored by the Innovation Defense Lab of the French Ministry of Defense, has put together […]
