Development of a WS2/MoTe2 heterostructure as a counter electrode for the improved performance in dye-sensitized solar cells

A facile large-area synthesis of a WS₂/MoTe₂ heterostructure via a sputtering–CVD approach on conductive glass substrates was demonstrated and, for the first time, it was used as a counter electrode (CE) for dye-sensitized solar cells (DSSCs).
