Safety tests with Organic PV in glass façades passed, installation in Marburg, Germany, is completed
Bretten and Nuremberg, Germany – Bischoff Glas Technik AG (“BGT”) and BELECTRIC OPV GmbH have completed a project in Marburg, designed by AiD architecture, where in glass laminated OPV elements have been used as a façade to cover an exterior lift shaft. The power generated by the OPV glass is used to ventilate the lift shaft to prevent heat accumulation inside. In order to comply with building codes and safety regulations for vertical integration of laminated glass, shatterproof tests were carried out and passed for this specific project. As these tests were passed at a certified test house, the “BI-Powersol” product range has proved its compliance with market regulations and demonstrates that OPV laminated in glass is a perfect material for the construction industry to use in multifunctional façades. For the project in Marburg, a family of customized, semi-transparent OPV modules was designed and manufactured by BELECTRIC OPV using blue-colored LISICON® active material supplied by Merck KGaA, which was then laminated into façade glass by BGT.
“We used the project in Marburg to test our BI-Powersol product against the building code and its associated safety regulations. Although this was carried out for a specific project – i.e. for the actual mounting scheme and layout used – it has an important impact for upcoming OPV projects. The achieved test certificates for vertically installed OPV in glass facades mounted at elevated height can now be transferred to other projects. Of course, all projects have different requirements but passing the first test is always an important milestone,” explains Klaus Wittmann, Member of the Board of BGT.
“The project in Marburg might not be a large one but the complexity of running such an installation project is almost independent of the dimensions when it comes to required testing,” adds Hermann Issa, Senior Director of Business Development and Sales at BELECTRIC OPV. “For this project we created a new OPV design series, which has been integrated into customized glass panels. This way we truly implement a unique façade.”
