Dual‐Function Scattering Layer of Submicrometer‐Sized Mesoporous TiO2 Beads for High‐Efficiency Dye‐Sensitized Solar Cells
TLDR
In this article, mesoporous beads are used as a scattering layer on top of a transparent, 6-μm-thick, nanocrystalline TiO 2 film.Abstract:
Submicrometer-sized (830 ± 40 nm) mesoporous TiO 2 beads are used to form a scattering layer on top of a transparent, 6-μm-thick, nanocrystalline TiO 2 film. According to the Mie theory, the large beads scatter light in the region of 600-800 nm. In addition, the mesoporous structure offers a high surface area, 89.1 m 2 g -1 , which allows high dye loading. The dual functions of light scattering and electrode participation make the mesoporous TiO 2 beads superior candidates for the scattering layer in dye-sensitized solar cells. A high efficiency of 8.84% was achieved with the mesoporous beads as a scattering layer, compared with an efficiency of 7.87% for the electrode with the scattering layer of 400-nm TiO 2 of similar thickness.read more
