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.

Fitness trackers, smart pharmaceutical packaging, adhesive solar films or steplessly dimmable windows: These are just a few examples of the applications that will be combined under the new focus topic Smart Living. LOPEC, the international exhibition and conference for the printed electronics industry, will thereby demonstrate the innovative opportunities that printed electronics offers to a wide variety of industries. The next LOPEC will take place from 24 to 26 March 2020.

Climate change is happening right now with proven negative impact on our environment, economies and societies. The key to slow down the global warming process is the significant reduction of greenhouse gases at all stages of industrial processes. Therefore, a massive turnaround of energy production towards low carbon technologies is essential. Heliatek (Dresden, Germany) brings an innovative organic solar film solution (HeliaSol) as a powerful means for the decarbonisation of the energy sector. HeliaSol is an ultra-thin, lightweight, flexible all-in-one solution that can add value to virtually any building surface — from glass, metal and concrete to polymer membranes — turning it into clean electricity generators, no matter if they are flat, curved or even semi-permanent.
