Organic solar cells in a so-called glove box in which they are exposed to artificial sunlight. Image source: Lunghammer - TU Graz By Philipp Jarke - Photovoltaic cells made of organic materials are light and flexible, which is why they are considered very promising. An international research network led by TU Graz is now aiming to increase the stability of the materials. Solar cells made of silicon have been around for 70 years. Organic solar cells, on the other hand, are quite new, but open up new possibilities for emission-free electricity production. These solar cells made of organic compounds achieve efficiencies of up to 19 percent, yet they are extremely thin, light and flexible. Applied to transparent film, they can be used in a wide variety of geometric shapes and colours in areas for which silicon-based solar cells are unsuitable.
