摘　　要：采用溶胶－凝胶法制备出ＴｉＯ２纳米晶胶体，通过丝网印刷技术直接在导电玻璃基底上制成胶体膜，经烧结处理得到海绵状的厚约１０μｍ纳米晶ＴｉＯ２膜．由于该膜的纳米结构和多孔性使其表面积比密实平整的膜高１０００倍左右．基于纳米晶体ＴｉＯ２半导体多孔膜和具有卓越光性能的有机染料光敏化剂，一种低成本。Nanocrystalline TiO2 colloidal dispersion was prepared by sol-gel method. Theproduction of porous film on conducting glass substrate was performed by straightforward screen-printing of the TiO2 dispersion. Asponge-like nanocrystalline TiO2 film (10μm thick) was obtained after sintering. The nanocrystalline film possesses an internal surface a thousand times greater than a dense, flat film. Based on the nanocrystalline TiO2 semiconducting porous film and the organic dye-photosensitizer with outstanding visible light-harvesting feature a new type of slor cell with low-cost, high-efficiency has been developed.
