Anthocyanin was extracted from red cabbage and onion peels using water. The demand for CNT applications is expected to increase due to their high conductivity and metallic or semiconducting characteristics. of the phase transformation and the factors affecting its observation. In the electrode counter given catalyst carbon, serves to accelerate the reaction kinetics of triiodide reduction process on transparent conductive oxide (TCO). There are three types of dye that have been studied, among others, chlorophyll, beta-carotene, and anthocyanin. The photo electrochemical parameter for solar cell by using chlorophyll extracted with DI water solvent showed the open circuit voltage (Voc) of 440mV, current short circuit (Isc) of 0.35mA and a fill factor (FF) of 0.49. phase transformation. The counter electrode is coated by a catalyst Pt (Platinum) to speed up the redox reaction with the electrolyte solution. Journal of Photochemistry and Photobiology A Chemistry. When a mechanical strain is applied to the ZnO@N719 film, a piezopotential is recorded and it depends on the intensity of the applied pressure. At optimized condition, energy conversion efficiency of 4.5% was obtained using mm small sized cell. The effectiveness of electron transfer was found to be related to the interaction between the chlorophyll dye and the TiO2 film surface. results clearly show that sepia melanin can be used as natural dye to DSSC sensitization. The natural dyes were extracted from Acanthus sennii chiovenda flower and Euphorbia cotinifolia leaf. The J-V characteristic curves of all fabricated cells were measured and analyzed. The parameters of solar cell are short circuit current (I SC), open circuit voltage (V OC Titanium dioxide, TiO2, is an important photocatalytic material that exists as two main polymorphs, anatase and rutile. It is promising for the realization of high cell performance, low-cost production, and non-toxicity. Usage under diffuse light and therefore, indoor applications are possible. The typical J-V curves of our solar cells under AM1.5 using a density of power 100 mW/cm2 were measured. This research on Dye-Sensitized Solar Cells (DSSCs) reengineering was carried out using TiO2 with natural dye (anthocyanin). can be replaced by natural dyes extracted from different natural gomphrenin-I which must be the compound of betalain family. The DSSCs based on MK dyes showed both high solar cell performance of up to 8% under simulated AM 1.5 G irradiation and good long-term stability under continuous simulated solar light (visible-light irradiation). A working electrode composed of semiconductor nanoparticles TiO2 that has been coated with dye molecules. A dye-sensitized solar cell (DSSC) was fabricated with natural chlorophyll dye extracted from pandan (Pandannus amaryllifolius) leaves as natural sensitizer. The absorption spectrum of the dye extract was compared with that of the dye adsorbed onto the TiO2 surface. A comprehensive analysis of the reported effects of that short-circuit current (Jsc) was remarkably influenced by those factors compared with conventional volatile electrolyte system. Their advantages are mainly low cost production, low energy payback time, flexibility, performance also at diffuse light and multicolor options. The lowest bandgap of dye also presented by extracted the chlorophyll with distilled water with 1.83eV and the absorption coefficient of 1.59 km-1. Therefore, in order to overcome these problems, we chose to use natural pigments as sensitizing dye. Evanjelene, Application of an ionic liquid-based electrolyte to a mm sized dye-sensitized solar cell. extracted dye from red amaranth leaves show, In this paper, DSSCs were prepared with natural dyes extracted from Jatropha and Chrysanthemum, a material, UV-Vis Spectrophotometer to observe on, analysis to determine the functional group, 2.1. Photovoltaic The, In this study, an ionic liquid-based electrolyte was applied to a mm sized dye-sensitized solar cell (DSC). Natural pigments are photosensitizers in dye-sensitized solar cells (DSSCs). Promising natural compounds are carotenoids, polyphenols and chlorophylls. Natural dyes in DSSCs have shown overall conversion efficiencies below 1%. Infra-red spectroscopy measurements were done to probe the structure and dynamics in our used dyes. The characterization of the cell gives I-V characteristics with open circuit voltage of 192.60 mV, short circuit current of 27.45 μA, fill factor of 29.88 %, and energy efficiency of 0.196 %.
