以Zn(NO3)2和曙红的混合溶液为沉积液，采用阴极电化学沉积法在ITO导电玻璃上制备了纳米多孔ZnO/曙红复合膜.考察了电化学预处理过程和曙红浓度对薄膜晶体结构、微观形貌和光学性能的影响.结果表明，引入短时间的电化学预处理过程能提高复合薄膜中ZnO的结晶质量，并诱导ZnO沿c轴定向生长.随着电沉积液中染料浓度的增大，所得薄膜的结晶质量下降，薄膜由六角晶颗粒逐渐向纳米多孔结构转变.当沉积液中曙红浓度为50μmol/L 时所得复合薄膜具有最大膜厚，装载的曙红量最高.以该复合膜为光阳极制作了太阳能电池原型器件，其开路电压为0.49V，短路电流为0.67mA/cm2，总光电转换效率为0.105%.
Nanoporous ZnO/Eosin Y hybrid thin films were fabricated on ITO substrate by cathodic electrochemical deposition from aqueous mixture of zinc nitrate and Esoin Y sodium salt. Effects of the pretreatment process and the dye concentration in the deposition bath on the crystal structure, morphology, and optical properties of the hybrid film were investigated. Results show that the introduction of a short electrochemical pretreatment process can enhance the crystallinity of ZnO, and ZnO crystals are induced to grow along the c axis direction by the pretreatment. As the concentration of Eosin Y in the bath increases, the crystalline quality of film decreases, and the deposit loses its hexagonal crystal facets gradually. Nanoporous ZnO/Eosin Y hybrid films with high dye loading content and thick film thickness is obtained by adding 50μmol/L Ensin Y in the deposition bath. The prototype dye sensitized solar cell device utilizing this hybrid film as photoelectrode is fabricated, exhibiting an open-circuit photovoltage of 0.49V, a short-circuit photocurrent density of 0.67mA/cm2，and an overall conversation efficiency of 0.105% under white light illumination.
