Fund Project: This work was supported by the National Natural Science Foundation of China (No. 20773142, 50533030), the National Research Fund for Fundamental Key Project (No. 2006CB806200, 2006CB932100 and 2007CB936403) and 863 project (No. 2007AA032348 and 2008AA05Z308).

Polypyrrole/polyvinylalcohol (PPy/PVA) foam was prepared by direct foam polymerization in water and then it was coated on the indium-tin oxide transparent conductive glass (ITO) to form conventional three-electrode cell.FTIR and UV-vis spectra were adopted to characterize the molecular structure and the absorption spectra of foam material,respectively.The porous structure of PPy/PVA foams and their photoelectric conversion behaviors were studied.The dimension of the pores is bigger than 100 μm in diameter.Compared with the smooth film,the V_oc and I_sc of the foam film enhanced by 1.58-fold and 5.59-fold,respectively.
