Abstract

The light-conversion efficiency of dye-sensitized solar cells (DSSCs) was improved about 13.5% and 6.0% by dispersing a down-conversion phosphor (DCP) and an up-conversion phosphor (UCP) in a TiO₂ layer, respectively. Also, further improvement in the efficiency could be achieved by forming DCP/UCP/TiO₂ double composite layers (η = 8.88%), which is about 21% higher than that of the cell (η = 7.36%) without the phosphor dispersion.
