| Abstract: | 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. FT-IR 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 Voc and Isc of the foam film enhanced by 1.58-fold and 5.59-fold, respectively. |
