Hydrogen-treated commercial WO3 as an efficient electrocatalyst for triiodide reduction in dye-sensitized solar cells
MetadataShow full item record
The electrocatalytically inactive commercial WO3 can be transformed into an efficient counter electrode (CE) material for dyesensitized solar cells (DSCs) viafacile hydrogen treatment. The energy conversion efficiency of the DSCs with the hydrogen-treated WO3CE was 5.43%, while the corresponding value for commercial WO3with the stoichiometric surface was only 0.63%.
