Sunny prospects for renewable energy : Molybdenum and tungsten carbides embedded in ordered nanomesoporous carbon materials as well as Mo 2 C 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.
