Kajian pH Klorofil Terhadap Ikatan Kimia Dye pada TiO2 sebagai Aplikasi Dye-Sensitized Solar Cell (DSSC)

Abstract

This study was conducted to examine the effect of pH on chemical bonding of chlorophyll dye on TiO 2 for application of DSSC. Variations of pH used in this study without the addition of buffers, acids, neutrals, and bases. The absorbance of chlorophyll dye and TiO 2 were characterized using UV-Vis spectrophotometer. The chemical bonds contained in TiO 2 -chlorophyll dye were characterized FTIR spectrophotometer. The efficiency of DSSC was calculated using I-V meter. The characterization results showed that pH of acids has the highest absorbance in the wavelength range 400-480 nm and 600-680 nm. The highest conversion efficiency of 0.013% with the transmittance of 89.3% at the wave number 3417 cm -1 .
