Light Scattering Effect

A light-scattering layer is widely used in highly efficient dye-sensitized solar cells (DSCs) because it improves the light-harvesting ability of a DSC by reflecting the light passing through the transparent TiO2layer. Among many parameters affecting this light-scattering effect, the thickness of the TiO2photoelectrode is also a significant parameter. However, most studies regarding the influence of the TiO2photoelectrode thickness on the light-scattering effect have only focused on the thickness of the transparent TiO2layer and have ignored the light-scattering layer thickness itself. Therefore, in this study, we analyzed the light scattering effect according to the thickness of the light-scattering layer and the resulting photovoltaic performance of the DSC. Finally, it was confirmed that the light-scattering effect is enhanced to some degree with the increase of the light-scattering layer thickness, while it is weakened when the light-scattering layer thickness is further increased.

Sensitized Solar Cells

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.

Light Scattering Effect

The formation of a micro-crater structure with optimal morphology in a dye-sensitized solar cell (DSSC) improved the light scattering effect without an additional light scattering layer. In addition, it provided a wide entrance for a fast and complete electrolyte infiltration into the TiO2 film.
