Heliatek (Dresden, Germany) has won the 2020 OE-A competition in the category: “Best Publicly Funded Project Demonstrator”. The award honours an innovative integration solution for façades using Heliatek’s organic solar films. A record of more than 20 applications from international companies were submitted and the OE-A selected the organic solar pioneer as one of three winners. This year’s competition was digital due to the cancelation of the LOPEC trade fair, the host event where the winners are usually being awarded.

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.
