Plasmon-enhanced efficient dye-sensitized solar cells using core–shell-structured β-NaYF 4 :Yb,Er@SiO 2 @Au nanocomposites

This is the authors' abstract. We don't add key points for this paper.

Core–shell-structured β-NaYF 4 :Yb,Er@SiO 2 @Au nanocomposites have been successfully prepared and applied in dye-sensitized solar cells resulting in an efficiency of 8.23%.
