Description
Summary:Research on the preparation of DSSC has been completed by using an anthocyanin dye from jengkol shell that copigmentation with gallate acid. The aim of this research is to know the variation of the duration of TiO2 immersion with the dyes, Effect of TiO2 coating on glass ITO, Effect of coating method of TiO2 paste with dye to DSSC efficiency. Variation of immersion used (12 hours, 24 hours, 36 hours, 48 hours); Variations in the amount of TiO2 coating used (1 layer, 2 layers, 3 layers, 4 layers, 5 layers); Variation of coating method of TiO2 paste with dye (TiO2 soaked with dye, TiO2 mixed with dye). DSSC efficiency is obtained from the calculation of voltage and strong current generated by multimeter. The results showed that the efficiency of DSSC was higher at 48 hours of soaking period, the amount of TiO2 coating on ITO glass showed the highest efficiency in coating 4 layers, the method of coating of TiO2 paste with dye showed the highest efficiency with the method of coating TiO2 immersed in dye. The UV-Vis characterization results indicate that the anthocyanin that is predominated by gallate acid shows a batochromic at a maximum wavelength of 536 nm. The result of FTIR characterization which obtained an absorption indicates the presence of OH bond which indicates the presence of anthocyanin in jengkol shell. Electrical energy conversion results obtained the highest efficiency at 48 hours of immersion and 4 layers of layer thickness by the method of TiO2 paste soaked in anthocyanin dye which is dikomigmented with gallate acid that is 1.40%.
