“…The dye from ipomoea leaves shows an efficiency of 0.31 % under extraction temperature of 50°C and pH value of 1.0 which is reported to be higher than spinach extract and the mixture [44]. Furukawa et al have extracted dyes from red cabbage and curcumin and an efficiency of 0.61 % has been achieved for mixture dye [45]. Several reports on DSSCs show that the mixture performed well over the individual dyes, and vice versa for a few extracts.…”

In the present work, the mechanism behind the functioning of the eco-friendly dye-sensitized solar cell was explored. Dye-sensitized solar cells were fabricated using natural dyes extracted from common pear (Opuntia dillenii) and red tamarind (Tamarindus indica), and 1:1 mixture. Betalain and anthocyanin were identified as the main pigments that sensitize the semiconductor TiO 2 film. The best conversion efficiency of 0.47 % was achieved from betalain dyes and 0.14 % from anthocyanin dyesensitized solar cell [under standard Air Mass 1.5 illumination (85 mW cm -2 )]. The mixture of dye (1:1 mixture) adsorbed onto TiO 2 exhibited an efficiency of 0.20 %. The light absorption behavior of extracted dyes was studied using ultraviolet-visible analysis. The influence of the binding nature of the dyes with TiO 2 surface on the efficiency of the solar cells was analyzed through Fourier transform infra-red analysis. The electrochemical impedance spectroscopy was used to find out the internal charge transfer resistance of the cells. The device incident photonto-current efficiency was obtained from 5 to 25 % for different natural dyes and found to coincide with the photocurrent-voltage characteristics and electrochemical impedance spectroscopy analysis.

IntisariArtikel ini membahas fabrikasi Dye Sensitized Solar Cell (DSSC) dengan menggunakan campuran dye antosianin dan klorofil sebagai fotosensitizer. Pencampuran dye bertujuan untuk memperlebar daerah serapan dye alami. Antosianin diekstraksi dari kol merah sedangkan klorofil dari daun bayam dengan metode maserasi. Komposisi dye divariasikan dengan perbandingan larutan antosianin:klorofil, yaitu 1:3, 1:1, dan 3:1. Variasi komposisi dilakukan untuk mengetahui pengaruh perubahan serapan dye terhadap efisiensi DSSC. Karakterisasi sifat optik menggunakan spektrofotometer UV-Vis, sedangkan karakterisasi sifat listrik dengan I-V meter. Hasil karakterisasi menunjukkan bahwa pada perbandingan 1:3 memiliki absorbansi tertinggi pada rentang panjang gelombang 400 nm hingga 450 nm dan efisiensi sebesar 0,15%. ABSTRACTThis article describes fabrication of Dye Sensitized Solar Cell (DSSC) using mixture of anthocyanin and chlorophyllas fotosensitizer. Mixing dye aims to widen the absorbance area of natural dye. Anthocyanin is extracted from red cabbage and chlorophyl from spinach leaves with maseration methode. Mixture composition of dye anthocyanin:chlorophyll varying at 1:3, 1:1, and 3:1. Composition variation is performed to determine the effect of absorbance change on the efficiency of DSSC. Optical characterization using UV-Vis spectrophotometer and electric characterization using I-V meter. The characterization result showed that rasio 1:3 hasthe highest absorbance at wavelength 400 nm to 450 nm with highest efficiency 0,15%. I. PENDAHULUANCahaya matahari merupakan sumber energi terbarukan. Energi cahaya matahari yang berupa foton dapat diubah menjadi energi listrik dengan menggunakan sel surya. Dalam perkembangannya, sel surya dibedakan menjadi 3 generasi, yaitu: generasi pertama sel surya berbasis monokristal dan polikristal, generasi kedua sel surya lapisan tipis, sedangkan generasi ketiga sel surya berbasis nanokristal, polimer, dan zat warna [1].DSSC merupakan salah satu jenis sel surya generasi ketiga berbasis zat warna (dye) sebagai penyerap foton (fotosensitizer) [2]. DSSC merupakan devais fotovoltaik yang ekonomis dan mudah dibuat [3][4][5], namun DSSC masih memiliki efisiensi yang relatif kecil dibandingkan dengan sel surya generasi pertama [6].Terdapat beberapa faktor yang mempengaruhi kecilnya efisiensi DSSC, salah satunya adalah jenis dye yang digunakan. Dye dengan daya serap yang tinggi dapat membantu meningkatkan efisiensi DSSC.

“…TiO 2 based photoanode can adsorb most of the available dyes which are commonly used as a sensitizer [28][29][30]. Therefore, natural dyes in TiO 2 based DSSC devices would be potential candidates in solving current photoanode development problems [31][32][33].…”

Porous photoanodes of dye-sensitized solar cells (DSSCs) can adsorb specific type of natural or organic dyes. Adsorption of the dye results in a change of the structural, morphological and optical characteristics of the photoanode. In this work, we present a comparative study on the adsorption effect of natural dye (Curcuma Longa sp.) on the structural, morphological and optical properties of mesoporous titanium dioxide (TiO 2 ) photoanode on indium tin oxide (ITO) coated glass. A number of investigations including XRD, UV-Vis spectroscopy, EDS, and SEM were carried out to observe the variations due to adsorbed dye on TiO 2 surface. XRD characterization revealed the effect of dye adsorption on specific surface area (SSA), crystallite size, and morphological index (MI). In this case, increasing SSA with decreasing particle size was found for both dye adsorbed and dye free DSSC photoanode samples. Also, the MI and SSA were found to be directly and inversely proportional to the crystallite size respectively. UV-Vis-NIR spectroscopy showed that dye adsorption changes the light absorption, transmittance, and optical bandgap of the photoanode. Average atomic mass percentage of titanium (Ti) and oxygen (O) obtained from EDS analysis proved the presence of TiO 2 in the mesoporous photoanode. In SEM images, significant morphological changes of mesoporous TiO 2 surface appeared because of dye adsorption.
