A preliminary study of DSSC with PEDOT carrageenan as electrolyte system

Abstract

This study aims to produce DSSC solar cells using PEDOT as a substitute for iodine. This experiment was carried out in the physics laboratory of the Tadulako University FKIP. TiO2 was deposited on FTO glass measuring 2.5 x 2.8 cm using the doctor blade method. TiO2 film was produced after heating in a furnace at 450 ☐C. Subsequently, the film was soaked in Routinized dye for 30 minutes. PEDOT Carrageenan Lambda 1:1 is then dripped on a TiO2/dye layer and covered with a platinum counter electrode. The results of measurements of current and voltage under direct sunlight with an intensity of 746 W/m2 are 32.2 µA and 97.5 mV, respectively. These results indicate that the PEDOT Carrageenan solution has enough potential to be developed as a substitute for iodine electrolyte in the DSSC solar cell device.

Different Roles between PEDOT:PSS as Counter Electrode and PEDOT:Carrageenan as Electrolyte in Dye-Sensitized Solar Cell Applications: A Systematic Literature Review

“…In other studies, PEDOT:Carrageenan was synthesized using λ-carrageenan with a ratio of 1:1 [ 49 ] and κ-carrageenan with a ratio of 1:2 [ 50 ] in weight percent (wt%). Both showed low performance of DSSC.…”

“…Both showed low performance of DSSC. It was caused by the rigidity of PEDOT chain; electron transport was not as efficient as compared to the liquid system [ 49 , 50 ]. Both studies have synthesized the PEDOT:Carrageenan with a similar process via in-situ polymerization by mixing EDOT monomer and carrageenan solution.…”

Fabrication of Fluorine-Doped Tin Oxide (FTO): From experiment to its application in physics learning

“…Fluorine-doped Tin Oxide glass is a type n semiconductor that is transparent and conductive. The spray pyrolysis method carried out by researchers to produce FTO glass in this study can be seen at the following link: https://www.youtube.com/watch?v=e1gEl-aC478 (Palamba et al, 2021). The FTO glass produced through the sintering and ionization processes in this experiment can be seen in Figure 2.…”

“…A few of the experimental activities carried out in making FTO glass and making DSSC solar cells in this study have been documented in video and have been uploaded online so that students can watch them (Palamba et al, 2021). This is expected to help support laboratory-based learning on some relevant physics materials such as Ohm's Law, X-ray Diffraction, Efficiency, and Electric Power.…”

Electrocatalytic and structural properties and computational calculation of PAN-EC-PC-TPAI-I2gel polymer electrolytes for dye sensitized solar cell application

“… 21,22 Until now, polysaccharides and modified polysaccharides based materials were in reality for their superior ionic conductivity at room temperature, which includes, for example, chitosan, 23,24 cellulose 25 and carrageenan. 26 Recently, Di Noto et al reported another two main kinds of hybrid inorganic–organic PEs that are mono-phase and multi-phase PEs. 27 Also, various inorganic filler were also reported, such as titania (TiO 2 ), zircronia (ZrO 2 ), carbon-nanotubes (CNT), graphene (Gr) and silica (SiO 2 ).…”
