Abstract

A research of the effects of pv cell modification to its performance in generating current and voltage with KI/KI3 electrolytes system has been performed. This research intended on studying the effect of ceramic membranes modified with titania (TiO2) on the performance of pv cells to generate current and voltage in generating currents and voltages. The pv cells that were assembled in this study have a thickness of 9.5 mm. Each cells were given a number code (ie: cell 0, cell 1, cell 2, cell 3, cell 4 and cell 5), according to the amount of titania coating on the used membranes. To study the performance of pv cells in generating current and voltage, the continuous flow of electrons system was used at the time of measurement. SEM and EDX analysis proved that the dip-coating process with titania on the cell 5’s ceramic membrane successfully modified surface and the pore size of the ceramicmembrane. The values of the performance characterization parameters of the cell 5 are as follows: voltage current short circuit (Isc) 0,085 mA, open circuit voltage (Voc) 80,9 mV, maximum current (Imax) 0,025 mA, maximum (Vmax) 41,8 mV, maximum power (Pmax) 1,045 x 10-6 Watt, Fill Factor (FF) 0,152 and energy coversion efficiency (η) 0,553 %.
