Scientists have published details of a “breakthrough” method for producing quantum dots – molecular specks of semiconductors – which they believe could pave the way for better and cheaper solar panels. The research at Rice University’s Center for Biological and Environmental Nanotechnology (CBEN) appears this week in the journal Small. The scientists describe a new chemical method for making four-legged cadmium selenide quantum dots, which previous research has shown to be particularly effective at converting sunlight into electrical energy. Quantum dots are “mega-molecules” of semiconducting materials that are smaller than living cells. They interact with light in unique ways to give off different-coloured light or to create electrons and holes, due partly to their tiny size, partly to their shape and partly to the material from which they are made.
