Telah dilakukan penelitian tentang pengaruh waktu annealing fotoanoda TiO2 terhadap efisiensi Dye Sensitized Solar Cells (DSSC). Fotoanoda DSSC dibuat dalam bentuk lapisan TiO2. Pembuatan lapisan TiO2 diawali dengan pencampuran bahan borid acid dan amoniumhexaflourotitanate yang kemudian ditumbuhkan menggunakan metode Liquid Phase Deposition (LPD) selama 15 jam di atas permukaan substrat kaca Indium doped Tin Oxide (ITO). Lapisan TiO2 yang telah tumbuh kemudian di annealing menggunakan furnace. Waktu annealing divariasikan 1 jam, 3 jam, 5 jam, 7 jam, 9 jam dan 11 jam. Temperatur annealing yang digunakan sebesar 450 ⁰C. Lapisan TiO2 yang terbentuk dikarakterisasi menggunakan I-V dan UV-VIS. Karakterisasi I-V menunjukan bahwa nilai efisiensi tertinggi 3,48% padaVoc 0,65 volt dan Jsc 17,62 mA/cm2 dimiliki oleh sampel dengan waktu annealing 7 jam. Life time tertinggi sebesar 14,92μs dimiliki oleh sampel dengan waktu annealing 5 jam. Celah pita energi yang didapatkan dari karakterisasi UV-VIS sebesar 3,20 eV – 3,23 eV, sesuai dengan celah pita energi lapisan TiO2 pada fase anatase. Kata kunci : DSSC, efisiensi, fotoanoda, lapisan TiO2,waktu annealing

Dye-sensitized solar cells (DSSCs) are fabricated with freestanding TiO2 nanotube arrays (TNTAs) which are incorporated with Au nanoparticles (NPs) and carbon materials via electrodeposition and chemical vapor deposition (CVD) method to create a plasmonic effect and better electron transport that will enhance their energy conversion efficiency (ECE). The ECE of DSSCs based on the freestanding TNTAs is 5.87%. The ECE of DSSCs, based on the freestanding TNTAs with Au NPs or carbon materials, is 6.57% or 6.59%, respectively, and the final results of DSSCs according to the freestanding TNTAs with Au NPs and carbon materials is increased from 5.87% to 7.24%, which is an enhancement of 23.34% owing to plasmonic effect and better electron transport. Au NPs are incorporated into the channel of freestanding TNTAs and are characterized by CS-corrected-field emission transmission electron microscope (Cs-FE-TEM) and elemental mapping. Carbon materials are also well-incorporated in the channel of freestanding TNTAs and are analyzed by Raman spectroscopy.
