Nanoparticulated TiO(2) fibers as one-dimensional long structures were introduced into TiO(2) P25 nanoparticle films using coelectrophoretic deposition. This prevented the usual crack formation occurring in wet coatings, and resulted in less porosity and higher roughness factor of the films that provided more favorable conditions for electron transport. The films used as the photoanode of a dye solar cell (DSC) produced 65% higher photovoltaic efficiency. TiO(2) fibers can be excellent binders in single-step, organic-free electrophoretic deposition of TiO(2) for DSC photoanode.
采用共电泳沉积的方法将纳米 TiO(2)纤维作为一维长结构引入 TiO(2) P25 纳米颗粒薄膜中。这防止了湿涂层中通常出现的裂纹形成，使薄膜的孔隙率降低，粗糙度因数增加，为电子传输提供了更有利的条件。用作染料太阳能电池 (DSC) 光阳极的薄膜的光电效率提高了 65%。TiO(2)纤维在用于 DSC 光阳极的无有机物质的一步电泳沉积 TiO(2)中可以作为优异的粘结剂。
