N2 - 2.5-4.5 nm SnO2, TiO2 and ZrO2 nanoparticles were synthesized by a solvo-thermal reaction, and applied for the fabrication of interfacial layers between transparent electrode and nanocrystalline TiO2 layer in DSSC. Each interfacial layer was formed by a self-assembly of the synthesized nanoparticles on the FTO glass, while the main nanocrystalline TiO2 layer with a thickness of 10 μm was coated by a doctor-blade method. All the interfacial layers enhanced the photovoltaic conversion efficiency of DSSC. Especially, SnO2/TiO2 coupled system improved the conversion efficiecy by 25 %. It is suggested that the SnO2 layer expedites the electron transfer from TiO2 to FTO glass, and blocks the back-transport of electrons.
