| dc.description.abstract | This paper is a product of a research aimed at developing a solar energy powered titanium dioxide solar cell. The experimental design involved preparation of various ratios of titanium dioxide: graphite /iodine/KI mixtures in each respective layer. Optimization was carried out by varying the mass of the constituents of each layer while maintaining the others constant to obtain the highest current-voltage outputs. The study investigated the effect of the thickness of TiO2 (the photo active layer) and the electronegative material layers on current-voltage output of the fabricated solar cell. The optimum electricity generation was observed at the ratio of TiO2/ Cx: I2: KI as 0.4: 0.3: 0.17: 0.01 g respectively. In conclusion, the results obtained on optimization of a blank cell, the open circuit voltage (VOC) and short circuit current density (JSC) of 0.083 V and 0.33µA were respectively obtained. These values were low confirming that a conducting medium was necessary for the migration of the generated electrons. The research generally recommends that there is need to employ improved technology to reduce presence of air packets which creates air gaps. | en_US |
