Abstract:
This paper reports on development of solar energy by titanium dioxide solar cell. Optimization of the material involved was carried out and the final cell constructed using the ratios that provided the highest current-voltage outputs. The study also investigated the effect of the thickness of TiO2 (the photo active layer) and electronegative material layers on current-voltage output of the fabricated solar cell. The optimum electricity generation in the ratio of TiO2/ Cx: I2: KI as 0.4: 0.3: 0.17: 0.01 g respectively. The e open circuit voltage (VOC) and short circuit current density were (JSC) of 0.083 V and 0.33µA respectively. However, despite the obtained values being low, there is potential application of this type of cell. It is recommended that improved technologies be employed to reduce the presence of air pockets which creates air gaps that resistance to migration of electrons.
