As part of the Design-PV project, Fraunhofer FEP has made significant progress in developing aesthetically appealing solutions for building-integrated photovoltaics. Technologies such as roll-to-roll nanoimprint lithography enable solar modules to be seamlessly integrated into building facades without compromising the design. Initial tests show that the modules are visually indistinguishable from conventional facade elements yet offer high energy efficiency. Photovoltaics are a key pillar ...
