Abstract

This Research were aimed to optimize structure of TiO₂ nanoparticles as an effort to increasing performance of Dye Sensitized Solar Cell (DSSC). Synthesis of TiO₂ were using sol-gel method with various time of aging process (6 and 7 days) and various calcination temperature (550 and 650⁰ C). Result from XRD characterization, 550⁰ C-7days TiO2 sample has the smallest grain size, 10,30 nm, with anatase phase. And 650⁰ C-6 days TiO2 sample has the biggest grain size, 15,69 nm, with bi-phase anatase-rutile. Result from measurement using I-V meter Keithley, the highest efficiency 0,09% was from 650⁰ C-7 days TiO₂ sample, and the lowest 0,012% from 550⁰ C-6 days TiO₂ sample.
