Highly Efficient Dye‐sensitized Solar Cells by Co‐sensitization of Organic Dyes and Co‐adsorbent Chenodeoxycholic Acid

Abstract

AbstractApproach 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.
