Pengaruh Konsentrasi Nikel dalam Klorofil pada Sifat Optik dan Konduktivitas Dye untuk Aplikasi Dye-Sensitized Solar Cell (DSSC)

Abstract: Penelitian ini bertujuan untuk mengetahui pengaruh doping nikel pada dye klorofil terhadap sifat optik dan konduktivitas dalam aplikasi DSSC. Doping nikel difokuskan pada pengaruh konsentrasi nikel pada dye klorofil sebagai fotosensitizer. Analisis sifat optik (absorbansi) larutan dye dan TiO2 menggunakan spektrofotometer UV-Vis. Analisis sifat optik untuk identifikasi gugus fungsional pada TiO2 setelah direndam dye menggunakan spektrofotometer FTIR. Konduktivitas larutan dye dihitung menggunakan I-V meter. Ha… Show more

“…The absorbance peak shows that, at that wavelength, the photon absorption is at maximum so that a lot of electrons are excited from HOMO to LUMO. When the dye can absorb light at a wider wavelength, the intensity of photon energy absorption is more effective, thereby increasing the number of excited electrons [12]. The effect of adding tartaric acid can shift the wavelength and increase the absorbance value because it has a greater dissociation set.…”

“…When the dye molecules are illuminated, the electrons at the HOMO level will obtain the energy to be excited to LUMO. Then, the electrons make a transfer to the molecule, and the charge transport generates an electric current [12]. Thus, the addition of tartaric acid successfully increases the conductivity of natural dyes.…”
