Abstract
To improve the efficiency of the DSSC circuit, light absorption from organic dyes must reach the maximum visible and near infrared spectrum values. This research examined improvement of efficiency DSSC transparent by optimizing of natural dyes hybrid synthetic dye (DN-F01). Compotition of natural dyes in this research used anthocyanin (black rice and black sticky rice). Anthocyanin dyes and DN-F01 with optimized choice of agents indicated that improved photovoltaic impacts contrasted with single individual dye sensitization and increased the absorption of solar light and allowed utilization of the photon energy more efficienly. With using spin coating method, FTO glass with TiO2 as working electrode and opposite electrode used FTO glass with platinum paste. To determine the efficiency of DSSC for characterization of electrical properties using Keithley I-V meter. The highest efficiency of the DSSC circuit is obtained from a combination of Black Rice Dye and 1% DN-F01 which is equal to efficiency (η) reached 1.065 % with an open circuit voltage (Voc) of 378 mV, short circuit current density (Isc) of 1.235 mA with fill factor (FF) of 0.656.
