- Abstract
nanoparticle TiO solid-state photoelectrochemical cell has been fabricated. The effect of ionic conductivity of a solid electrolyte of polyacrylonitrile (PAN)–propylene carbonate (PC)–lithium perchlorate (LiClO) on the performance of a photoelectrochemical cell of indium tin oxide (ITO)/TiO/PAN–PC–LiClO/graphite has been investigated. A nanoparticle TiO film was deposited onto ITO-covered glass substrate by controlled hydrolysis technique. A solid electrolyte of PAN–LiClO with PC plasticizer prepared by solution casting technique was used as a redox couple medium. The room temperature conductivity of the electrolyte was determined by AC impedance spectroscopy technique. A graphite electrode was prepared onto a glass slide by electron beam evaporation technique. The device shows a photovoltaic effect under illumination. The short-circuit current density, J, and open-circuit voltage, V, vary with the conductivity of the electrolyte. The highest J of 2.82 μA cm and V of 0.56 V were obtained at the conductivity of 4.2 × 10 Scm and at the intensity of 100 mW cm.
