Al@SiO2 Core-Shell Microflakes as Metal-Based Light Scattering Layer in Dye-Sensitized Solar Cells

A metal-based light scattering layer (MLSL) for dye-sensitized solar cells (DSSCs) is formed from Al@SiO2 core-shell microflakes prepared and coated on a thin porous TiO2 electrode (approximately 4 μm thick). The DSSC corresponding to a TiO2 electrode with an MLSL exhibits a low electron transport r...

Description
Summary:A metal-based light scattering layer (MLSL) for dye-sensitized solar cells (DSSCs) is formed from Al@SiO2 core-shell microflakes prepared and coated on a thin porous TiO2 electrode (approximately 4 μm thick). The DSSC corresponding to a TiO2 electrode 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.
