We demonstrated the construction and performance of dye-sensitized solar cells (DSCs) based on nanoparticles of TiO2coated with thin shells of MgO by simple solution growth technique. The XRD patterns confirm the presence of both TiO2and MgO in the core-shell structure. The effect of varied shell thickness on the photovoltaic performance of the core-shell structured electrode is also investigated. We found that MgO shells of all thicknesses perform as barriers that improve open-circuit voltage (Voc) of the DSCs only at the expense of a larger decrease in short-circuit current density (Jsc). The energy conversion efficiency was greatly dependent on the thickness of MgO on TiO2film, and the highest efficiency of 4.1% was achieved at the optimum MgO shell layer.

A metal-based light scattering layer (MLSL) for dye-sensitized solar cells (DSSCs) is formed from Al@SiO2core-shell microflakes prepared and coated on a thin porous TiO2electrode (approximately 4 μm thick). The DSSC corresponding to a TiO2electrode with an MLSL exhibits a low electron transport resistance in the TiO2/electrolyte interface. Electron collection efficiency is greatly improved. Photovoltaic performance measurements indicate that the power conversion efficiency of the DSSC with the MLSL doubled from 1.37% to 2.96% (for an active area of 0.25 cm2), which is better than the 2.1% achieved by a DSSC with a conventional TiO2-based light scattering layer (TLSL) obtained under identical experimental conditions.
