First real time movies of the light-to-current conversion in an organic solar cell

Photovoltaic cells directly convert sun light into electricity and hence are key technological devices to meet one of the challenges that humankind has to face in this century: a sustainable and clean production of renewable energy. Organic solar cells, using polymeric materials to capture sun light, have particularly favorable properties. They are low-cost, light-weight and flexible, and their color can be adapted by varying the material composition. Such solar cells typically consist of nanost...
