EXPO 2015: Field of polymer solar cells in the German Pavilion

"Feeding the Planet, Energy for Life" is the core theme of EXPO 2015 in Milan. For this edition, the pavilions were built with a focus on sustainability, water, climate, biodiversity and innovation. The German Pavilion "Field of Ideas” has broken new ground and decided to resort to organic photovoltaic (OPV) modules which are embedded in a flexible film.

OPV were installed in the German Pavilion to create stylised trees that provide shade for visitors and generate energy at the same time.

This innovative technology plays an essential role in reducing external use of energy in the field of construction and therefore saves resources.  

In addition to being sustainable, it also opens up entirely new opportunities in the field of architecture and matches with the specifications of architects and designers.

OPV uses polymer solar cells to convert light into electricity: light is converted into a flux of charged particles that are creating the current. This phenomenon is made possible by the combination of several types of materials, including plastics, all having distinct electrical and optical characteristics.

This innovative and flexible photovoltaic cell, integrating energetically active components, opens the field of creativity for architects and designers. The spectrum of its application in design is broad: OPV can be integrated in many accessories going from sport to leisure via fashion. With respect to architecture, OPV offers many benefits for energy harvesting in façade design and urban furnishing.

EXPO 2015 started 1st May and ends at the end of October.  The Universal Exposition brought together 145 countries representing 94% of world’s population. They participate either via self-built pavilions or in the context of Clusters. Three international organisations, 13 NGOs and 5 corporate pavilions are also participating in the event. Approximately 29 million visitors are estimated, to come from all over the world, and will have the possibility to attend an interesting program of 7,000 events.
