22_13b/2012Solar Cells: Heterojunction Engineering of CdTe and CdSe Quantum Dots on TiO2 Nanotube Arrays: Intricate Effects of Size-Dependency and Interfacial Contact on Photoconversion Efficiencies (Adv. Funct. Mater. 13/2012)

On page 2821, Wey Yang Teoh and co-workers report that the interfacing of CdTe and CdSe quantum dots (QD) on aligned TiO2 nanotube (TNT) arrays enables the fabrication of efficient, low-cost, photo-electrochemical solar cells. By improving the quality of the QD-TNT interface, multiple-fold enhancement in photoconversion efficiency can be achieved and the charge injection efficiencies of QDs of different sizes are exhibited.
