Abstract

Abstract The aim of this research was to determine the effect of coaction performance of two natural dyes which was Malabar melastome (Melastoma malabathricum). (SD) extract and nipa palm (Nypa fruticans) (NP) extract to photovoltaic properties of the fabricated DSSCs. Both plants are planted in different habitat (water and terrestrial). Experiment was carried out in 3 coaction which were combination of leaves (DN) and fruits (BH) from each plant. It was BH-SD+DN-NP, BH-SD+BH-NP and DN-SD+BH-NP. Extraction used absolute ethanol solution as solvent at the ratio of 1:3. Leaves, flowers and fruits from Malabar melastome and nipa palm were washed with distilled water then cutted in small pieces and subsequently dried at 45°C for 24 hours. The dried materials were ground and immersed in solvent for 7 days at room temperature in a dark room. All filtrate was obtained and used as dye photosensitizer. The DSSC encapsulation comprised of a photo electrode and counter electrode which were stacked up sandwich-like cell. Both electrodes were clamped with clamps on both sides prior dripping with electrolyte solution. The research revealed that co-action of two natural dye from Malabar melastome and nipa palm are able to increase the efficiency of DSSC. The maximum of field factor occoured in BH-SD+BH-NP while minimum was in BH-SD+DN-NP, 0.3816 and 0.2572 respectively. The co-action efficiency of natural dye reached maximum in BH-SD+DN-NP and minimum in DN-SD+BH-NP which were 7.7414% and 1.2229% respectively.
