Until now, the only photovoltaic cell with an inorganic p-type absorber tapped out at 0.1% conversion efficiency. Researchers from INAC recently broke this record, reaching yields of 1.25% with a prototype developed under a French National Research Agency-funded project. The cell uses a new pair of materials (quantum copper-indium-sulfur dots and nickel oxide) and perfects […] >>

TMR (tunnel magnetoresistance) sensors promise greater sensitivity to probe for hidden defects and higher spatial resolution to pick up even the most minute defects. The technology is a product of the EU-backed project Imagic, in which Leti participated. The sensors will end up in in Eddy current NDT equipment used to inspect metal parts. The […] >>

Researchers at INAC used a plasma growth technique to produce sheaths of graphene perpendicular to the electrode of a supercapacitor. These sheaths, just nanometers thick, are used to build a layer of graphene that is several microns high, which is deposited on a silicon substrate—a geometry that makes it easier for the ions in the […] >>

France-based startup Iprasense (www.iprasense.com) unveiled its Cytonote digital microscope in late 2014 in London. Today, the company is pleased to announce its first sales of the very-large-field (30 mm2) microscope. The Cytonote microscope was developed by an Iprasense-Leti joint lab and uses lensless imaging technology patented by the CEA. The microscope is used to monitor […] >>

How do you get smart-building systems and sensors working together if they all use different communication protocols? Leti has come up with an ingenious solution to this problem: it uses a middleware, LINC, to share important information—temperature, hygrometry, and presence, for instance—regardless of the technology used. In this way, information can be shared across multiple […] >>
