Future energy harvesting goes transparent

Transparente, organische Solarzellen

Organic solar cells are light-weight and can be fabricated in almost arbitrary shapes and colors – or even semi-transparent. Their unique properties pave the road to new applications in our daily life never thought possible before.

Two studies illustrating future applications of organic photovoltaics are presented:

In the model of Mies van der Rohe’s “Farnsworth House” we integrate organic solar modules into glass façades with different orientations, generating an all-day stable solar energy output. The model also shows that new energy conversion technologies do not at all stand in the way of an attractive design.

The solar glasses demonstrate organic solar cells driving smart mobile applications. Here, for the first time, the lenses as the largest available area harvest solar energy with transparent organic solar cells.

Both demonstrators do not only illustrate the high adaptability of the organic solar cells’ shape and size, but also highlight their color variability. The module assembly hanging down from the ceiling exemplifies the color space.

This research is supported by funding from the German Federal Ministry of Education and Research (BMBF), the European Union, the Baden-Wuerttemberg Stiftung, and the Deutsche Forschungsgemeinschaft (DFG).
