A novel photoelectrochemical cell consisting of a set of organic thin films which generate photocurrents in opposite directions was fabricated. The polythiophene film containing 5,10,15,20-tetraphenylporphyrin (TPP) and fullerene (C60) generated anodic photocurrents in the presence of ferrocene, while that containing TPP alone generated cathodic photocurrents under aerobic condition. The combination of these two film-modified electrodes showed a better cell performance than the simple sum of these two independent photoelectrochemical cells. A push-pull type, double-driven photoelectrochemical cell is proposed in this paper.
