Abstract

original image

Always wear a coat: On a plastic substrate graphene is coated with a conducting polymer (PEDOT), resulting in a flexible composite film. The film is used as counter electrode in dye-sensitized solar cells (DSSCs) instead of platinum/transparent conducting oxides (TCOs). The performance of the TCO- and platinum-free counter electrode rivals that of convenential DSSCs.
