Near-Infrared Sunlight Harvesting in Dye-Sensitized Solar Cells Via the Insertion of an Upconverter-TiO2 Nanocomposite Layer

Er3+,Yb3+ co‐doped LaF3‐TiO2 nanocomposites (UC‐TiO2) are inserted as a middle layer in a novel tri‐layer photoanode design (see Figure) of a dye‐sensitized solar cell (DSSC). The Er3+,Yb3+ co‐doped LaF3 part of the nanocomposite helps capture near‐infrared (NIR) light by converting it into visible...

Description
Summary:Er3+,Yb3+ co‐doped LaF3‐TiO2 nanocomposites (UC‐TiO2) are inserted as a middle layer in a novel tri‐layer photoanode design (see Figure) of a dye‐sensitized solar cell (DSSC). The Er3+,Yb3+ co‐doped LaF3 part of the nanocomposite helps capture near‐infrared (NIR) light by converting it into visible light absorbable by the dye hence opening the road for the development of DSSCs with higher conversion efficiency and photocurrent output.
