Mesoporous SnO2 agglomerates with hierarchical structures as an efficient dual-functional material for dye-sensitized solar cells†
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
