Description

Dye-sensitized solar cells (DSSCs) is fabricated from a combination of relatively popular materials containing nanocrystalline TiO${}_2$, electrolyte solution containing I${}^−$/I${}^{3-}$ redox mediator, counter electrode, and natural dye. In this work, the natural dye extract from Artocarpus lacucha with methanol solvent as sensitizers. The photo to current conversion efficiency (η = 0.69%) was obtained by Artocarpus lacucha under AM 1.5 illumination. The short circuit photo-current density (Jsc), open circuit voltage (Voc) and fill factor (FF) are 2.01 mAcm${}^{-2}$, 0.57V and 0.60, respectively.
