Polythiophene/fullerene bulk heterojunction solar cell fabricated via electrochemical co-deposition

We report a polythiophene/fullerene (C60) bulk heterojunction solar cell fabricated via electrochemical co-deposition of polythiophene (PTh) and fullerene on an indium tin oxide (ITO) glass electrode modified with a thin layer of poly (3,4-ethylenedioxylthiophene) (PEDOT). Although the amount of C60 incorporated into the film was relatively low, the photovoltaic performance of the cell based on the polythiophene/fullerene (PTh/C60) composite film was remarkably improved.
