Performance of P. betle extraction as sensitizer in dye-sensitized solar cells (DSSCs)

Abstract

Natural dyes extracted from Piper betle (P. betle) pigment, was utilized and researched as sensitizer in DSSCs application. The optical characteristics of the extracted dye and photovoltaic performance of the cells were studied. The extracts showed UV-vis absorptions in the range of 530–560 nm with broad maxima absorption at∼ 430 nm. For P. betle the photovoltaic performance of the sample with 3.16μm-thick ZnO produced the best results with open-circuit voltage (VOC), short-circuit current density (JSC), fill factor (FF), and energy conversion efficiency (η) values of 0.33 V, 6.35 mA/cm2, 0.52, and 1.09%, respectively.
