摘要
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 100μm 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.
