The anatase TiO2nanoparticle films with different thicknesses have been fabricated through screen printing method, and CdS and CdSe quantum dots (QDs) have been deposited on TiO2films in turn through successive ionic layer adsorption and reaction (SILAR) method. It has been found that the amount of QDs decreases significantly and the size of QDs increases obviously with the depth increasing in TiO2nanoparticle films, and the size distribution of QDs shifts to large-size direction with the TiO2film thickness increasing. Furthermore, a qualitative model of CdS/CdSe quantum dot distribution in TiO2nanoparticle films has been obtained. After optimizing the TiO2film thickness, the quantum dot-sensitized solar cells (QDSCs) with about 10 μm thick nanocrystalline TiO2electrodes and Pt counter electrodes have reached relatively high power conversion efficiencies of 3.26 ± 0.10% under one sun illumination (100 mW cm−2, AM 1.5 G).
