Fabrication Dye Sensitized Solar Cells (DSSCs) Using β-Carotene Pigment Based Natural Dye.

Abstract

Abstract. The adsorption characteristic of natural dye has been studied on harvesting light using purification process. The purification process used for separation pigment photosynthesis of syngonium leafs was called fractionation. The first fractionation of the dye contains pigment of β-carotene . The absorpton spectrum of β-carotene has been investigated by using Uv-Vis spectroscopy. The Fourier Transform Infrared revealed that the binding of the dye was on the surface of TiO2. Analysis absorbance and energy gap of the dye has been investigated by using Uv-Vis spectroscopy and Tauc relation. The cells were illuminated under 100 mW/cm 2 AM 1.5 condition. The performance of the cells with sensitized the fractionation dye has a short circut current density (Jsc) of 0.27 mA/cm 2 , an open circuit photovoltage (Voc) of 0.4V, and Fill Factor (FF) of 68.89%. Furthermore, the overall efficiency of DSSC is 0.074%. The low efficiency for the fractionation cell based dye sensitized solar cells due to the weakness of interaction between dye molecule and the surface of TiO2.

The Photoelectrochemical Response of a β-Carotene Coated Hematite Nanoarchitecture Biophotoelectrode with Cauliflower and Nano Octahedron Types Morphologies

“…absorbs in the green part of the solar spectrum, thus has been studied along with TiO 2 nanocatalyst for increasing its light-harvesting capacity and thus increasing hydrogen production. [28][29][30] β-Carotene displays an absorption maximum at 453 and 484 nm 31 and hence have been sensitized on TiO 2 Solar Cells to study and increase the efficiency 32 extensively. Following this, in the current study, we have demonstrated the efficiency enhancement of hematite nanoarchitectures with β-Carotene coating in the form of a 2-fold increase in the photocurrent density magnitude.…”

How Components of Dye-sensitized Solar Cells Contribute to Efficient Solar Energy Capture

“…(Table 6) shows the performance of DSSCs using carotenoid extracts from achiote seeds [105], Curcuma longa [143], golden trumpet [107], gardenia yellow [144], tomatoes [145], Syngonium sp [146], walnuts [147] and Gardenia blue [144] as photosensitizers. The relatively poor performance of DSSCs containing carotenoids as DS is likely due to the extensive conjugated double bond system that can hold the excited electron by formation of many stable resonance forms there by reducing the chance of electron jump to the photoanode.…”
