摘要：

We present herein a facile one-step low-temperature hydrothermal approach for in situ growth of metal selenides (Co0.85Se and Ni0.85Se) on conductive glass substrates. The as-prepared metal selenides on conductive substrates can be used directly as transparent counter electrodes for dye-sensitized solar cells (DSSCs) without any post-treatments. It is found that graphene-like Co0.85Se exhibits higher electrocatalytic activity than Pt for the reduction of triiodide. As a consequence, the DSSC with Co0.85Se generates higher short-circuit photocurrent and power conversion efficiency (9.40%) than that with Pt.
