Rare-earth-incorporated ternary Ce Cd S quantum dot-sensitized solar cells.

This work presents a new absorber material - rare-earth-doped ternary Ce Cd S quantum dots (QDs) - for solar cells. Ce Cd S QDs were synthesized by partially replacing the cation Cd in the binary sulfide CdS with Ce using a two-step solution processing process. First, Ce-S QDs were grown on a mesoporous TiO electrode.
