摘要：
An edge-oriented WS2 as a counter electrode (Cis reported for highly efficient dye-sensitized solar cells (DSSCs). Converted directly from a mesoporous interconnected WO3 structure by a rapid sulfurization process at high temperature, the oriented WS2 exposes a large number of active edge sites that lead to high catalytic activity toward triiodide reduction in DSSCs. The DSSC device with optimized edge-oriented WS2 CE exhibits a power conversion efficiency (PCE) of 8.85% at 100 mW cm-2, which is higher than that of Pt (7.20%). © 2015 WILEY-VCH Verlag GmbH & Co.
