Abstract

The aim of this paper is to demonstrate the influence of the TiO 2 with different sintered time regarding the performance of photovoltaic characteristics of DSSCs. A layer of TiO 2 with a thickness of ~8-10 μm and an area of 0.25 cm 2 was prepared by depositing TiO 2 nanoparticles paste onto a fluorine-doped tin oxide (FTO) sbustrate by doctor blade technique, followed by sinterring at 450°C with 4 differennt sintering times: 10 min, 20 min, 30 min, and 40 min. The Pt solution was dripped on FTO substrate works as counter electrode. SEM, XRD and I-V curve were conducted for the material analysis. The photovoltaic characteristics were measured under AM 1.5 sunlight simulator. The results reveal that the different sintered time of TiO2 working electrode did affect the photovoltaic conversion efficiency. In conclusion, TiO 2 sintered for 30 min yields the highest power conversion efficiency of 6.273%.
