Improved photon harvesting by employing C70 in bulk heterojunction solar cells

Abstract:

To achieve higher efficiencies in organic solar cells, ideally the open circuit voltage (VOC), fill factor (FF) as well as the short current density (JSC) have to be further improved. However, only a few suitable acceptor molecules, e.g. C60, are currently available for the photoactive layer. Despite a good electron mobility on the order of 1×10−3 cm2/Vs the absorption of C60 in the visible sun spectrum is low. From polymer bas...
