摘要
Approach to highly efficient dye-sensitized solar cells(DSSCs)by co-sensitization of organic dyes,AZ6+AZ5 with co-adsorbent chenodeoxycholic acid(CDCA)is presented.The power conversion efficiencies(PCEs)of 8.55%and 8.31%are obtained from DSSCs co-sensitized by AZ6(0.3 mmol/L)+AZ5(0.1 mmol/L)with CDCA concentration of 5 and 20 mmol/L in one step cocktail,respectively.The latter shows high stability in a period of 653 h under ambient conditions.
