Title: Fabrication and characterization of photovoltaic devices based on perovskite compounds with TiO{sub 2} nanoparticles

Perovskite-type photovoltaic devices were fabricated by a spin-coating method using a mixture solution. The compact and meso-porous TiO{sub 2} of the solar cells were fabricated from TiO{sub 2} nanoparticles and sol, and the photovoltaic properties and microstructures were characterized. The conversion efficiencies were improved by the combination of TiO{sub 2} nanoparticles and sol. Current density was also improved by increasing numbers of spin-coatings of meso-porous TiO{sub 2}. Thick meso-porous TiO2 layers would assist the construction of perovskite layers and block of the leak current.
