This paper deals with the current transport mechanism of solid state photoelectrochemical cells of ITO/TiO 2 /PVC–LiClO 4 /graphite as well as the physical properties of a component of a device affecting its performance. The principle of operation and a schematic energy level diagram for the materials used in the photoelectrochemical cells are presented. The device makes use of ITO...
The photovoltaic characteristics of a photoelectrochemical cell of ITO/TiO2/PVC-LiClO4/graphite are reported. This paper is concerned with the influence of light intensity and temperature on short-circuit current density, Jsc and open-circuit voltage, Voc of the device. The photoelectrochemical cell material was a screen-printed layer of titanium dioxide onto an ITO-covered glass substrate, which...
A single-layer and multi-layer titanium dioxide (TiO2) coated with dye porphyrin thin films were prepared on Quartz Crystal Microbalance (QCM) using sol-gel dip coating method and were tested for sensing of volatile organic compounds (VOCs). The porphyrin was 2,3,7,8,12,13,17,18-octaethyl- 21H,23H-porphine cobalt (II). The sensing sensitivity was based on the change in the fundamental frequency of...
This paper reports the effect of ionic conductivity of the solid polymeric electrolyte of polyvinylchloride-lithium perchlorate (PVC-LiClO 4 ) on the performance of a solar cell of ITO/TiO 2 /PVC-LiClO 4 /graphite. Titanium dioxide films have been used as a photoelectrochemical solar cells. The films were deposited onto a ITO-coated glass substrate by a screen printing technique...
