Double-shelled copper chalcogenide (Cu2−xSe and Cu7S4) nanocages of about 250 nm sizes are synthesized respectively by using Cu2O nanocubes as sacrificial precursor via Kirkendall diffusion and etching. Both the double-shelled Cu2−xSe and Cu7S4nanocages are demonstrated to be excellent counter electrode (CE) materials in quantum dot-sensitized solar cells (QDSSCs) and exhibit high electrocatalytic activities for polysulfide electrolyte regeneration. The QDSSCs using the double-shelled Cu2−xSe and Cu7S4nanocages as CEs show power conversion efficiencies (PECs) of 4.76 and 4.53%, respectively, which are 19.6% and 15.3% higher than the corresponding devices using the single-shelled Cu2−xSe and Cu7S4nanocages as CEs. The overall enhancement of photovoltaic performance including the fill factor, short-circuit current density and PEC is attributed to the larger CE-electrolyte interface provided by the double-shelled nanocages facilitating fast electron transfer in the QDSSCs.
