Mesoporous TiO₂ microspheres (MSs) were successfully synthesized by the direct hydrolysis of TiCl₄ in ethanol aqueous solution using cetyltrimethyl ammonium bromide (CTAB) as a template. X-ray diffraction (XRD) revealed a rutile structure for TiO₂ in all the products. Scanning electron microscopy (SEM) revealed that the TiO₂ microspheres had an average diameter of 700 nm, and they were composed of packed nanoparticles that had a mean size of about 16 nm. Films with or without TiO₂ microspheres, as a scattering layer on top of the TiO₂ nanocrystalline layer, were prepared by the doctor-blade method. CdS/ CdSe quantum dots (QDs) were grown on films by chemical bath deposition (CBD) to form QD sensitized solar cells (QDSCs). Ultraviolet-visible and diffuse reflectance spectra showed that these micro-spherical structures were favorable for the deposition of QDs and a relatively higher light scattering effect was observed. This effectively enhanced light harvesting and led to an increase in the photocurrent of the QDSCs. As a result, a power conversion efficiency of 4.5% was obtained, which is 27.7% higher than that of QDSCs without scattering layers and 10.2% higher than that of QDSCs with traditional scattering layers composed of 20 and 400 nm TiO₂ solid particles. We attribute this improvement to their higher light scattering effect and longer electron lifetimes.
