Building-integrated photovoltaics

In contrast to standard solar modules, building-integrated photovoltaics (BIPV) are designed to comply with preferred façade designs as well as building regulations.


Buildings as energy providers

Our dedication to support modern architects has helped advance printed organic photovoltaics (OPV) from a research topic to successful commercial applications. OPV modules are lightweight and flexible laminates that, can be easily added to a variety of construction materials including standard lamination in glass. The module design can be adapted, enabling a unique choice of colors, shapes, and degrees of transparency. This allows OPV to meet the functional and aesthetic demands of architects for building-integrated photovoltaics.

Leading the BIPV task force at SolarPower Europe

BIPV products are building elements with an integrated photovoltaic function. The BIPV industry as such is relatively young and involves value chain players from material suppliers to module manufacturers, façade companies, and building engineers. To support the market entry of BIPV elements, the task force hosted by the industry association SolarPower Europe aims to inform policy makers on the European level about the opportunities and challenges of this sector.

Presenting organic photovoltaic materials at EXPO 2015 in Milan

At EXPO 2015 in Milan, Italy, visitors experienced a unique alliance of architectural creativity and solar cells. The central design elements were expressive membrane-covered shelters in the shape of sprouting plants featuring seamlessly integrated organic photovoltaic modules. The example of these solar trees shows important advantages of OPV technology like freedom of design and versatile adaptability, especially with respect to architectural applications.

DSSC installations at our headquarters

The lamellar elements with a reddish shimmer at the southern facade of the modular Innovation Center in Darmstadt are a real eye-catcher. These elements move, orienting themselves to the sun in order to maximize performance. The reddish color comes from dye-sensitized solar cells inside the lamellae. Apart from their main task of shading the room from the sun, they also produce electricity. This shows how the usually inactive facade can be used to generate electricity from sunlight in a very resource-efficient and climate-friendly way.

OPV shade sail at the African Union building in Addis Ababa

OPVIUS has developed a unique energy-generating shade sail in the shape of the African continent for the African Union building, in collaboration with Carl Stahl Architektur GmbH and ourselves. The immense flexibility in shape and design offered by organic solar cells was a convincing factor in winning the project. The simple manufacturing procedure is highly scalable, and based on classic industrial processes such as printing and coating. Our active OPV materials (lisicon®) are key enablers for these types of solar cells.

Gray OPV modules for building applications

Our lisicon® formulation enables semi-transparent, gray-colored OPV modules with superior power generation performance of more than 50 W/m². This joint development with OPVIUS was showcased in solar modules at the Adaptive Architectures and Smart Materials Conference in Chicago, Illinois. The main showpiece was a number of free-form modules taking the form of laminated glass panels mounted on steel ropes to create a lightweight, curtain-wall-type facade. Modules of this type open up limitless design possibilities for modern architecture.
