The SnO<sub>2</sub> nanoparticles have an average diameter of 15–20 nm and porous SnO<sub>2</sub> nanosheets have a large specific surface area of 37.39 m<sup>2</sup>/g. As photoanodes, the dye-sensitized solar cell (DSSCs) based on porous SnO<sub>2</sub> nanosheets show a superior power conversion efficiency of 0.562%, improved by 134.2% compared to pure SnO<sub>2</sub> nanoplate (0.240%). The efficiency improvement could be attributed to the unique porous architecture, which provides efficient electron channels and excellent ability of light scattering.
