    Abstract

    Transparent TiO 2 films were deposited onto a base electrode comprising an InSnO 2 glass substrate using the (alkoxide) sol-gel technique. Lead phthalocyanine was subsequently vacuum sublimed onto the TiO 2 surface. The resulting InSnO 2/TiO 2/PbPc/Au heterojunction cell was investigated for its illuminated current density/voltage, and spectral characteristics. The ideality factor (m) and saturation current (J o) were determined from current density/voltage J(V) measurements. Photoelectrical measurements were conducted under both simulated solar radiation and within a wavelength range of 300-900 nm. This allowed calculation of open circuit voltage V oc, short circuit current J sc, fill factor FF, quantum efficiency Z and the overall conversion efficiency. Typical photovoltaic characteristics were obtained indicating the potential of the device for solar cell applications. The power conversion efficiency η was ∼0.001%; improvements are therefore required.
