春季到秋季的家庭熱水主要由安裝在外墻上的太陽能集熱器提供,太陽能能夠提供所需熱量的66 % ) 。 -
Because of the anatase ' s broad eg ( 3. 2ev ), the absorption thresholds correspond to 380nm for the tio2. consequently, only the ultraviolet fraction of the solar irradiation can be active in the photoexcitation processes using pure tio2 solid. the high recombination rate of charge carrier and low efficiency of quantization are also the deficiencies of pure tio2
由於tio _ 2的帶隙較寬(約3 . 2ev ) ,半導體的光吸收波長范圍窄(主要在紫外區) ,故其太陽能的利用效率低,且還存在半導體載流子的復合率高,量子化效率低等缺陷。
