In the race for ever higher efficiency levels, an Helmholtz Zentrum Berlin (HZB) development team has once again pulled ahead. The groups of Steve Albrecht and Bernd Stannowski have developed a tandem solar cell made of the semiconductors perovskite and silicon that converts 29.15 per cent of the incident light into electrical energy. This value has been officially certified by the CalLab of the Fraunhofer Institute for Solar Energy Systems (ISE) and means that surpassing the 30 per cent efficiency mark is now within reach.
The increasing electrification of on-board vehicle systems is one of the major trends of the 21st century, entailing the installation of more and more electronics, electronic control units, sensors and antennas in a vehicle. Therefore, the automotive industry increasingly relies on RFID marking solutions in logistics and manufacturing operations.
Printed electronics is revolutionising medicine. LOPEC, the international exhibition and conference for the printed electronics industry in Munich, Germany, will present new developments from this area from 24 to 26 March 2020. Read excerpts from a conversation with LOPEC plenary speaker John A. Rogers, professor at Northwestern University in the US state of Illinois, about monitoring systems and other flexible electronic devices that can be worn directly on the skin or implanted inside the body.
