Organic Photovoltaics

Organic and printed photovoltaics (OPV) is an emerging, clean energy technology enabling a wide range of applications. OPV devices typically comprise a substrate (glass or plastic), semi-transparent electrodes (silver grids and conductive polymer or indium-tin oxide (ITO)), and photo-absorbing layers (bulk or P/N heterojunctions). OPV can be made on flexible substrates, enabling lightweight and conformable power sources suitable for many emerging applications like wearables and mobile devices. They also offer design and process flexibility for integration in large area industrial products, for example in building facades and also function in diffuse light.

Building- integrated Organic Photovoltaics

Covering facades with solar cells becomes possible with lightweight OPV foils, improving the energy balance of buildings. The freedom of choosing transparency and color of the modules allows to merge function and design.

Harvesting Energy

Organic Photovoltaic cells are semitransparent and can be adjusted to any color. Thus, they integrate the dimming function and are harvesting energy to supply sensors and integrated electronics with power.
