Quantum Dot (QD) Sensitizer on the Surface of TiO2 Film: Effect of Metal Salt Anions Dissolved in Chemical Bath on the Distribution Density of SILAR-Grown PbS QDs

摘要

Recently, quantum dots (QDs) have attracted much attention for a variety of optoelectronic applications based on their strong light absorption and bright emission over a broad range of spectrum. One of the most recent and active areas is related with QD-sensitized solar cells that utilize inorganic QDs as a light harvester. QDs are considered as an ideal sensitizer because their absorption range from visible to IR spectrum can be tuned easily by changing the size or composition of QD itself.
