The design of hybrid materials for electronic properties offers many opportunities for the integration of functions. 1–3 In this context, the incorporation of single wall carbon nanotubes (SWNTs) into polymeric solar cells is appealing because of their excellent electron transfer abilities, 4 and because they are flexible and optically transparent. 5 They may therefore play a key role in creating flexible organic solar cells. Current bulk heterojunction solar cells composed of poly-3- ...
