| 英文摘要 | Cauliflower-like tio2 rough spheres, which are about 200 nm large, have greatly enhanced light harvesting efficiency and energy conversion efficiency of dye-sensitized solar cells (dsc), due to their high light scattering effect and large bet surface area (80.7 m(2) g(-1)) even after calcinations at 450 degrees c for 30 min. the large size tio2 rough and smooth spheres, produced at different initial temperatures by hydrolysis of ti(obu)(4) with p105 (eo37po56eo37) or f68 (eo78po30eo78) tri-block copolymer as structural agents, have nearly the same diameter of similar to 275 nm and strong light scattering effects in the wavelength of 400-750 nm. however, rough spheres have even higher light scattering effect and larger bet surface area than smooth spheres for the roughness of the surface. by adding 25 wt.% large tio2 spheres into the over-layer of tio2 film composed of similar to 20 nm tio2 particles as light scattering centers, the energy conversion efficiency of the film containing rough spheres reaches 7.36%, much larger than that of smooth spheres (6.25%). from another point of view, the tio2 rough spheres may have the satisfying ability in other fields of application such as photo-catalysis, drug carriers and so on.
