Paper Abstract

Using an aerosol technique, in which ultrasonically formed droplets of titanium tetraisopropoxide are pyrolysed, thin films of nanosized particles of anatase TiO2 can be deposited. The size of the particles and the film morphology are strongly dependent on deposition parameters like reaction temperature, concentration of the precursor, and gas flow. At best, films can be formed consisting of homogeneous, stoichiometric anatase TiO2 particles with a size of about 50 nanometer. With these films, solar cells have been constructed by spin casting poly(3-octyl)thiophene (P3OT) on top. Cell characteristics of the devices with a 1 μm film of TiO2 and an equivalence of 30 nm of PT inside the pores are Isc: 0.25 mA/cm2, Voc: 0.72 V, FF: 0.35 and η: 0.06% using white light with an intensity of 1000 W/m2 (not AM 1.5). The IPCE is 2.5% at 488 nm.
