Solar Cells: Morphological Stabilization by Supramolecular Perfluorophenyl‐C₆₀ Interactions Leading to Efficient and Thermally Stable Organic Photovoltaics (Adv. Funct. Mater. 10/2014)

A solar cell device under sunlight irradiation is shown by Y.-J. Cheng and co-workers. The device contains a photoactive layer which can efficiently absorb the light. There are three components in the active layer: the green flying ribbons represent the p-type poly3-hexylthiopehene polymers, while the blue shining balls represent the n-type PC61BM, and the red balls are the other PCBM-based fullerene material, functionalized with pentafluorophenyl groups. The device is described in detail on page 1418.
