Breakthrough in search for new quantum dot materials for highly efficient solar cells (ChemE/OM)

Researchers of the section Optoelectronic Materials at the Dept. of Chemical Engineering at TU Delft and Toyota Motor Company, Europe, have found that a single photon can generate three mobile electrons in layered structures of quantum dots that are coupled in a special way. The unconventional process of carrier multiplication is highly promising for exploitation in a new generation of cheap and very efficient solar cells.
