“…KA affords an open circuit voltage ( OC ) of 0.76 V and a short circuit density of 0.32 mA/cm 2 under stimulated power input of 120 W/m 2 . The efficiency of semisynthetic sensitizer KAis comparable with reported natural dye such as chlorophyll and anthocyanin dye [47][48][49] and higher than other heavy metal dyes [39] as well as metal free organic dye [40].…”

Sensitization of heavy metal free organic dyes onto TiO 2 thin films has gained much attention in dye sensitized solar cells (DSSCs). A series of new kojic acid based organic dyes KA -were synthesized via nucleophilic substitution of azobenzene bearing different vinyl chains A -with kojyl chloride . Azo dyes KA -were characterized for photophysical properties employing absorption spectrometry and photovoltaic characteristic in TiO 2 thin film. The presence of vinyl chain in A -improved the photovoltaic performance from 0.20 to 0.60%. The introduction of kojic acid obtained from sago waste further increases the efficiency to 0.82-1.54%. Based on photovoltaic performance, KA achieved the highest solar to electrical energy conversion efficiency ( = 1.54%) in the series.

“…Synthetics dyes from hydrazonoyl and their derivatives reported obtain the efficiency of DSSC of 0.00009-0.003% [24]. Natural dyes from five plants Amaranthus caudatus, Bougainvillea spectabilis, Delonix regia, Nerium oleander and Spathodea campanulata obtained the highest efficiency of DSSC reached 0.610% from Amaranthus caudatus [25]. Natural dyes from beet, red cabbage, strawberry, spinach, mallow, and henna extract obtained the highest efficiency of 0.229% [26].…”

The development of dye sensitizer is growing in line with the increasing demand for renewable energy. A research to obtain a dye sensitizer that is economical, safe, and produces a great value of DSSC efficiency is a challenge unresolved. On the other hand, the efforts for waste reduction are also intensively conducted to create better environment. In this paper, the variation of synthetic dye wastes from batik industries have been successfully applied as dye sensitizer and fabricated on DSSC cells. Congo red (1.0133%) yielded higher efficiency than rhodamine B (0.0126%), methyl orange (0.7560%), and naphthol blue black (0.0083%). The divergence of the efficiency of DSSC is very dependent upon the chromophore group owned by dye. This study has proven that the more chromophore group possessed by dye, the higher the efficiency of DSSC generated. This research concludes that the dye wastes have a bright future to be implemented as dye sensitizer on solar cells.

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. Ada 2 jenis dye yang biasanya digunakan dalam pembuatan DSSC, yaitu dye sintetis dan * E-MAIL: mfistiani27@student.uns.ac.id alami. Dye alami lebih ramah lingkungan dan tersedia secara melimpah di alam dibandingkan dengan dye sintetis [7][8][9], namun daerah serapan yang dimilikinya relatif sempit. Dalam penelitian ini 2 jenis dye yang berbeda dicampurkan agar daerah serapannya menjadi lebih lebar. Dye yang digunakan ialah antosianin dan klorofil. Antosianin merupakan zat warna merah dasar, sedangkan klorofil merupakan zat warna hijau yang biasanya terdapat pada daun [10]. Antos...
