Abstract

Mesoporous SnO₂ agglomerates with hierarchical structures and a high surface area were fabricated through a molten salt method. The SnO₂ demonstrated high photoelectric conversion efficiencies of 3.05% and 6.23% (with TiCl₄ treatment) in dye-sensitized solar cells, which are attributed to its dual functionality of providing high dye-loading and efficient light scattering.
