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 Elm in diameter. Compared with the smooth film, the V(OC) and I(SC) the foam film enhanced by 1.58-fold and 5.59-fold, respectively. (C) 2010 Qiang Xie.
