The short-circuit current density (JSC), the open-circuit voltage (VOC), the fill factor (FF), and the overall efficiency (&eta;) were 14.45 mA/cm2, 0.756 V, 0.65, and 7.1%, respectively. The single-crystalline TiO2 NRs with length 200&ndash;500 nm and diameter 30&ndash;50 nm were prepared by simple hydrothermal methods. The dye-sensitized solar cells with pure TiO2 NR and pure TiO2 NP electrodes showed only a lower light-to-electricity conversion efficiency of 4.4% and 5.8%, respectively, compared with single-crystalline TiO2 NRs. This can be attributed to the new NR/NP bilayer design that can possess the advantages of both building blocks, ie, the high surface area of NP aggregates and rapid electron transport rate and the light scattering effect of single-crystalline NRs.Keywords: dye-sensitized solar cell, TiO2 nanorod, bilayer electrode Hoda HafezZhang LanQinghua Liet alDove Medical PressarticleMedical technologyR855-855.5Chemical technologyTP1-1185ENNanotechnology, Science and Applications, Vol 2010, Iss default, Pp 45-51 (2010)
