Paper Title:
Effects of Phosphoric Acid on the Photovoltaic Properties of Photovoltaic Cells with Laminated Polypyrrole-Fullerene Layers
  Abstract

By applying phosphoric acid in dispersion of fullerene in the fabrication of polypyrrolefullerene photovoltaic cells we present laminated active structure of polypyrrole and subsequent fullerene layers, with two other reference methods to incorporate fullerene: (i) in a physically blended monolayer; and (ii) in a blend from chemical reaction. I-V characteristics show that a blend monolayer cell can display photosensitive effect however without photovoltaics; a bilayer cell displays photovoltaics either in dark or in illumination, with its VOC up to1V and its JSC up to12.5 μA cm-2 under AM1 105 mW cm-2 condition. The results demonstrate that phosphoric acid is effective in dispersion of fullerene as well as combining it with polypyrrole layer in a photovoltaic cell. The effects of phosphoric acid in fabricating a bilayered photovoltaic cell are discussed mainly in terms of H-bonding.
