Pioneering Facade-Integrated Organic Photovoltaics with Heliatek’s Solar Films
Facade-Integrated Organic Photovoltaics at EStW
Members of the Solar TAP Industry Network Erlanger Stadtwerke (EStW) and Heliatek have jointly installed nearly 100 organic photovoltaic (OPV) modules on the metal facades of the EStW building. These flexible, adhesive-backed solar films were applied directly to the building surfaces simplifying installation and demonstrating the potential of OPV technology in urban environments.
EStW and Heliatek connected through Solar TAP and initiated this collaboration. HI ERN, a leading institute in PV performance evaluation using infrared imaging and drone-based inspection, is now monitoring the installation’s performance as part of Solar TAP’s initiative to help both partners optimize the technology.
This collaboration aims to not only assess real-world performance but also drive improvements in Heliatek’s OPV products.
