摘要：The aim of this paper is to demonstrate the influence of the TiO2with different sintered time regarding the performance of photovoltaic characteristics of DSSCs. A layer of TiO2with a thickness of ~8-10 μm and an area of 0.25 cm2was prepared by depositing TiO2nanoparticles 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, TiO2sintered for 30 min yields the highest power conversion efficiency of 6.273%.
