Heliatek (Dresden, Germany) has announced that its award-winning organic solar film HeliaSol has passed the stringent criteria of the Solar Impulse Foundation to be approved as one of its listed efficient solutions. The so-called “1000solutions” programme was launched by Bertrand Piccard (the first person that circumnavigated the world in the solar airplane “Solar Impulse”) to promote innovations that help protecting our environment in a profitable way. Currently more than 400 of these solutions are listed in the five categories:
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.
