摘　　要：In this study,analysis was performed of the macro characterization of solar cells with chlorophyll dye from Syzygium paniculatum,using scanning electron microscopy(SEM)and energy-dispersive X-ray(EDX)analysis.Solar cells based on titanium dioxide(TiO_(2))nanomaterial and chlorophyll dye from S.paniculatum can increase efficiency due to flavonoids and batulinic acid content.Photoanode TiO_(2) is one of the essential factors determining the photovoltaic properties of dye-sensitized solar cells(DSSCs)and shade,which broadens the absorption spectrum.Furthermore,the method used in this research involved varying the colour of the S.paniculatum leaves,namely red(SP-Red),green(SP-Green)and a red-green mix(SP-Mix).From a macro analysis,SEM observations resulted in agglomerated and aggregated TiO_(2)-polyethylene glycol(PEG)-dye layers with irregular shapes.EDX observation resulted in a peak in Ti at 5 keV and all constituents were detected with an O:Ti ratio of 3.47:1 for FTO-TiO2/PEG using SP-Green.Measurement of voltage-current(IV)using a digital multimeter indicated that the best occurred in the DSSC with SP-Green,resulting in a short-circuit current density(Isc)of 0.0047 mA/cm2,an open-circuit voltage(Voc)of 0.432 V,a charging factor(FF)of 0.749 and an efficiency(η)of 3.724%.
