Abstract

• Zinc oxide particle was synthesized from Ixora Coccinea Leaf (Pone Na Yeik) extract and zinc acetate by biological method. The product was confirmed by X-ray diffraction (XRD), and UV–Vis spectroscopy. Dye Sensitized Solar Cell (DSSC) was assembled by the green prepared ZnO and Ixora Coccinea petal (Pone Na Yeik flower) pigment. In this work, the green synthesis of zinc oxide was used as photoelectrode while carbon counter electrode was applied. After DSSC architecture, JSC (short-circuit photocurrent), VOC (open-circuit photovoltage), FF (fill factor) and η (efficiency) were investigated from the current - voltage (I-V) measurement.
