This latest research builds on previous work by the Lester Wolfe Professor of Chemistry, Moungi Bawendi in producing quantum dots as thin, uniform coatings with accurately governed properties. Able to be applied to a range of materials, the tiny particles contained in the film are individually very efficient at turning light into electricity.

According to Vladimir Bulovic, Fariborz Maseeh Professor of Emerging Technology in MIT’s School of Engineering, bringing them together in thin coatings "allow them to do what they do as individuals – to absorb light very well – but also work as a group, to transport charges."
