Low‐Cost Molybdenum Carbide and Tungsten Carbide Counter Electrodes for Dye‐Sensitized Solar Cells

Sunny prospects for renewable energy: Molybdenum and tungsten carbides embedded in ordered nanomesoporous carbon materials as well as Mo2C and WC are proposed as alternatives to the expensive platinum counter electrode (Pt CE). The preparation of the CEs was optimized, and the dye-sensitized solar cells (DSCs; see picture) equipped with these CEs show a higher energy conversion efficiency than those devices with a Pt CE.
