Abstract

ABSTRAK - Telah dilakukan fabrikasi dye sensitized solar cell (DSSC) berdasarkan konsentrasi AlCl3 dengan semikonduktor oksida Al2O3@TiO2 core-shell dan kulit manggis sebagai dye fotosensitizer. Terdapat enam variasi konsentrasi AlCl3 dan metode yang digunakan dalam sintesis adalah metode sol gel dengan suhu kalsinasi 240°C. Al2O3@TiO2 core-shell powder dikarakterisasi menggunakan XRD, FTIR, zeta potensial dan particle size analyzer (PSA). Dari hasil karakterisasi XRD didapatkan fase berupa ɣ-Al2O3 dan TiO2 anatase. Karakterisasi FTIR menunjukkan bilangan gelombang 439 cm-1 dan 583 cm-1 yang merupakan gugus fungsi Ti-O-Al sebagai tanda bahwa coreshell terbentuk. Hasil karakterisasi zeta potensial menunjukkan bahwa sampel Al2O3@TiO2 core-shell dengan konsentrasi 2,75 gr memiliki tingkat aglomerasi yang lebih tinggi dibandingkan kelima sampel yang lain. Ukuran partikel yang dihasilkan adalah 316,3 nm sampai 526,6 nm. Kurva I-V DSSC dengan konsentrasi AlCl3 2,25 gr menunjukkan hasil terbaik dengan efisiensi sebesar 0,000057% ============================================================================================= ABSTRACT - Dye-sensitized solar cell (DSSC) based on AlCl3 concentration has been fabricated with Al2O3 core-shell semiconductor oxide and mangosteen dyes as fotosensitizer. Six variations in AlCl3 concentration synthesized using sol gel method and calcined at temperature of 240oC were used in this research. Al2O3@TiO2 core-shell powder were characterized by XRD, FTIR, zeta potential and particle size analyzer (PSA). ɣ-Al2O3 and TiO2 anatase phases were identified from XRD test. Wavenumbers at 439 and 583 cm-1 from FTIR test showed Ti-O-Al functional groups and this functional group can indicate that core-shell has formed. Zeta potential test showed that Al2O3@TiO2 core-shell sample was highly agglomerated for sample with 2.75 gr concentration. Particle size of core-shell was ranging from 316.3 to 526.6 nm. The best efficiency of DSSC was obtained for sample containing 2.75 gr AlCl3, i.e., 0.000057%
