主要研究了半导体材料TiO_2的部分特征,光谱吸收率与TiO_2膜厚度成正比,TiO_2膜在烧结前呈水合物团块状结构,表面粗糙度大,空气中烧结后呈等粒或椭圆粒状镶嵌结构,表面粗糙度比未烧的小,在抽真空加氮气烧结后成等粒状结构,表面较光滑,在空气中烧结的TiO_2膜放至光敏染料中泡1h后呈等粒状结构,表面较光滑。从TiO_2光电池器件输出电功率来看,TiO_2膜在空气中烧至450℃时的电输出的功率比在氮气中烧至530℃的高,印刷TiO_2膜的丝网目数为500目时,电输出功率较佳。
Part of the characteristics of the semiconductor material TiO 2, the spectral absorption rate and the thickness of the TiO 2 film is proportional to the TiO 2 film was hydrate prior to sintering bulk lump structure, surface roughness, sintered in air was grain or oval granular mosaic structure , The surface roughness than the non-burned small, after the vacuum sintering plus nitrogen into an equal granular structure, the surface is relatively smooth, sintered in air TiO 2 film to the photosensitive dye soak for 1h was granular structure, the surface is smooth. From the output power of TiO_2 photocell device, the power output of TiO_2 film in air at 450 ℃ is higher than that in nitrogen at 530 ℃, and the mesh size of printed TiO_2 film is 500 mesh. The electrical output Better power.
