Abstract

Porous conductive glass was designed and prepared by depositing transparent conductive film (TCF) on inner surface of pores and outer surface of porous glass (PG) with nano-size pores. In the present study, tin oxide (SnO₂) was deposited onto the inner surface of PG pores to form a nanocomposite first by using chemical vapor deposition (CVD) method. TCF of SnO₂ or indium tin oxide (ITO) was then deposited onto the outer surface of the nanocomposite by using spray pyrolysis deposition, laser ablation (LA) and CVD methods. Surface area of obtained porous conductive glass is about 10⁵ times more than that of flat dense TCF. The obtained samples are translucent due to the scattering of light. This kind of porous conductive glass is expected to provide a huge reactive field for functional materials used in photoelectric devices, which in turn increases devices' function such as light-to-energy conversion efficiency drastically.
