Balance Is Key to Making Quantum-dot Solar Cells Work

Something in the physical structure of these cells seems to trap their electric-charge carriers (known as electrons and holes), but researchers have been hard-pressed to figure out exactly what. Now, for the most widely used type of quantum dots, made of compounds called metal chalcogenides, researchers from MIT may have found the key: The limiting factor seems to be off-kilter ratios of the two basic components that make up the dots. The new findings — by Jeffrey Grossman, the Carl Richard Soderberg Associate Professor of Power Engineering, materials science and engineering graduate student Donghun Kim, and two other researchers — were reported this month in the journal Physical Review Letters . In bulk quantities of lead sulfide, the material used for the quantum dots in this study, the ratio (known by chemists as “stoichiometry”) of lead atoms to sulfur atoms is exactly...
