CQDs can be incorporated into a liquid that can be sprayed onto something flexible such as plastic or film in single-atom layers. This film can then coat weird-shaped materials. The amazing part is, Kramer has shown that using this spray technique does not cause any loss in solar-cell efficiency. In some cases, it even has improved performance over the traditional batch-processing method. The sprayer for the CQDs is made out of a spray nozzle that steel millls use to cool steel with a water mist and art store-quality air brushes.
In the future, CQDs could be sprayed on to house roofs, airplane wings, and car roofs (a car roof could then power 24 CFL bulbs!) for a start. It will be interesting to see how quickly this technology can be manufactured and used widely!
