Hybrid perovskite photovoltaic cells can deliver yields of more than 20%. However, they do not age well. Researchers from Irig and INES joined forces to investigate the mechanisms that underpin the formation of the best-known hybrid perovskite, MAPbI3*, which is synthesized in thin layers. The research revealed two things that explain the behavior of cells […] >>

Leti developed a packaging for its new GaN (gallium nitride) power components that could unlock the components’ full potential. The two-sided cooled module stands out for its extremely low parasite inductance. The risk of overvoltage is reduced, allowing switching at 350 V and 10 A, and a switching speed of 15 ns. The researchers think that their chances […] >>

Irig’s electronic nose, which was transferred to startup Aryballe Technologies, now has an even broader range of uses. But first it will have to be usable in the field and at wider temperature ranges. Researchers at Irig redid some of the basic science on the device, comparing theory with lab testing results. They looked at […] >>

Touch interfaces can now effectively simulate the feel of sand, fabric, or a control panel button, an advance made possible by placing ceramic piezoelectric switches on a screen and making them vibrate at several dozen kHz. However, the switches must be bonded to the screen manually, which augments production costs. Leti has found a solution in […] >>

What if LEDs could be used instead of mercury*-vapor lamps in a wide range of bacteria-killing UV devices? Researchers from Irig and Institut Néel recently made a major step toward mercury-free UV lamps. They successfully and significantly augmented a UV LED’s p-type doping level of aluminum nitride (AlN) by adding a small fraction of indium […] >>
