Efficient binary organic thiolate/disulfide redox mediators in dye-sensitized solar cells based on a carbon black counter electrode

摘要

New thiolate/disulfide redox couples (M~-/M2) were introduced and also combined with T~-/T2, resulting in more efficient binary redox couples. The binary redox couples, in particular M~-/T2, yielded a high energy conversion efficiency and reasonably stable performance with the carbon black counter electrode for dye-sensitized solar cells.
