I will summarize recent progress on the performance of “plastic” solar cells fabricated from self-assembled bulk heterojunction nanomaterials comprised of semiconducting polymers and fullerenes. The role of processing additives such as alkane-dithiols in controlling the nanomorphology will be discussed. The improved nanoscale morphology facilitates mobile charge carrier generation, charge transport to, and charge collection at the electrodes.
