Solid-State Synthesis of ZnO Nanostructures for Quasi-Solid Dye-Sensitized Solar Cells with High Efficiencies up to 6.46%

• Solid-state synthesis of ZnO nanostructured building blocks is presented in this work for the fabrication of high efficiency quasi-solid dye-sensitized solar cells (DSSCs). The sponge-like photoanode has high optical density and better connections. Baking the photoanode at low temperature, photoconversion efficiencies of up to 6.46% are yielded by the quasi-solid DSSCs. Furthermore, we demonstrate better stability of our ZnO quasi-solid DSSCs.
