Abstract

The efficiency of Mangifera Indica was improved upon by utilizing three known sensitizers- inherent in its leave and peel. The results obtained in this experiment may vary due to the versed mango germplasm collection which is about 150. The experimental technique adopted was in line with objective of furthering the efficiency of Mangifera Indica. The natural dye sensitized solar cell (DSSCs) obtained was tested via solar simulator and UV spectrophotometer. When the DSSCs was analyzed in the dark, it resulted in a low negative value of short circuit current Isc = -1.00 × 10-7 mA and a low short circuit voltage Voc = 0.06V due to the absence of light. When the DSSCs was analyzed in light, its short circuit current (Isc) = 1.22 × 10-2 mA, an open circuit voltage (Voc) = 0.53v,Vmax = 0.35v, Imax = 1.00 × 10-2 mA. The Mangifera indica dye have peak transmittance at 220nm and good transmittance level between 400nm to 800nm. There were no transmittances between 240nm to 420nm. This shows that the range of the expected photoelectric conversion effect is between 240nm to 420nm. Though the overall conversion efficiency (Eff) =0.345%, the range of its photoelectric conversion effect gives more room for better results.
