Synthesis of hierarchical structure cuprous oxide by a novel two-step hydrothermal method and the effect of its addition on the photovoltaic properties of ZnO-based dye-sensitized solar cells

The ZnO-based dye-sensitized solar cell of addition cuprite Cu2O, which induced bridging character was possibly related to its ability to inhibit the inherent shortages of ZnO electrode, and generate a lower charge transfer resistance, abudant dye-loading quantity, longer electron lifetime, and reduced charge recombination.392
