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.
