Abstract: This report presents making of nanocrystals-based solar cells for light energy conversion in relation to the Final Year Project as part of the course requirement of the School of Electrical and Electronic Engineering. The solar cell that is being fabricated during the project process is the quantum dot solar cell. The initial part of the report will describe the process of fabrication of samples with the use of ITO glass and TiO2 solution. Various methods and concentrations of the solution were used to get the better efficiency solar cell. The samples were fabricated mainly two methods: glass rod rolling and paint brush brushing method and also using the spin coater to create a TiO2 layer on the ITO glass. Samples using different coating methods were compared and also using different method of soft baking. The samples after coating with TiO2 were hard baked and go through chemical bathing stages. Various concentrations were tested to get the ideal concentration of solvent to quantum dot. A layer of reservoir was created on the quantum dot coated sample and before combining with the counter electrode, electrolyte was added to the sample. With the adding of electrolyte, the solar cell is finished. The later part of the report will be describing the various testings of solar cell under the sunlight, SEM and characterization. Characterization is done by using the solar simulation. The solar cells are tested with no light and with light conditions and the graphs and test data were obtained.
