Abstract

A dye-sensitized indium tin oxide (ITO)/titanium dioxide (TiO 2)/polyacrylonitrile (PAN)-propylene carbonate (PC)-lithium perchlorate (LiClO4)/graphite solar cell was fabricated, and its performance was tested in the dark and under the illumination of a 100 mW/cm2 light. Three TiO2 samples were used in the device, namely, uncoated TiO2, a TiO2 film coated with methyl red dye, and a TiO2 film coated with coumarin dye. The films were deposited onto an ITO-covered glass substrate by a controlled hydrolysis technique assisted with a spin-coating technique. The films were characterized by scanning electron microscopy to determine their average grain size. The smallest grain size (48 nm) was obtained for the uncoated film. An electrolyte of PAN-LiClO4 with PC plasticizer was prepared by a solution-casting technique. A graphite electrode was prepared on a glass slide by an electronbeam evaporation technique. The device showed rectification properties in the dark and showed a photovoltaic effect under illumination. The device with the uncoated TiO2 film showed the highest short-circuit current density (2.0 lA/cm2) and an open-circuit voltage of 0.64 V because it possessed the smallest grain size.
