Formatted abstract
The following report is a preliminary study of the research and experimental procedures required to complete the thesis on, “Nanostructured Titania Dye Sensitised Solar Cells: Study of the effects of variations in the TiO2 Film Thickness and Dyeing Times”. The aim of this thesis is to study the mechanisms behind the operation of Titania solar cells. In particular the aims are as follows:
• Research and obtain an understanding of Dye Sensitised Solar Cells
• Vary the thickness of the titanium dioxide semi-conductor films in these cells and analyse the effects.
• The effects of varying the dyeing time of the films will also be studied.
• Titania powder characterisation.
The report is experiment based with the following methodology being used: research, experimentation, analysis from which conclusions and recommendations will be formed.
The main findings of this report are regarding the Titania powder characterisation. Properties of commercial grade Titania powder used in the production of semiconductor films were found to change after the powder has been calcined in furnace.
Methods for the production of micron thick Titania films were also analysed. A repetitive dry coating technique was found to give a consistent film. The different methods used to produce the films will be further tested to find the light to electricity efficiency. From these results an optimum method and thickness will be found.
This report is predominantly a review of the research which has been undertaken in this field. The procedures required to complete the experimentation and analysis of these solar cells are also detailed.
