▎ 摘  要

Bi2Se3/reduced graphene oxide (rGO) composite was successfully synthesized by a facile microwave-assisted hydrothermal method and applied as a counter electrode for efficient dye-sensitized solar cells. By this means, the size and distribution of the formed Bi2Se3 nanoparticles onto a flexible graphene sheet were effectively controlled, which is crucial for achieving high electrocatalytic activity on I-3(-) reduction. Mainly due to the homogeneous single-layer immobilization of Bi2Se3 nanoparticles on a graphene sheet with high density, BiG2 exhibited the highest catalytic activity and the lowest electrolyte diffusion resistance. Adye-sensitized solar cell with BiG2 as a counter electrode can yield 7.09% photoelectric conversion efficiency, which is comparable to that of the cell with a Pt-film counter electrode (6.23), exhibiting the application potential of BiG2 as a low cost non-Pt CE materials for DSSC.
