    Scientists develop efficient spray-on solar cells technology

    Researchers from Sheffield University, England, have created a spray-painting method that allows solar cells to be sprayed onto surfaces.

    The process involves applying thin layers of perovskite – a calcium titanium oxide mineral – at rates high enough for large-volume manufacturing.

    According to the team of scientists, perovskite is inexpensive and can absorb light nearly as well as silicon.

    The spray on cells can currently reach efficiency levels of around 11 per cent but are expected to reach perovskite’s ideal performance rate of 19 per cent with further development.

    The scientists believe that their approach could one day be scaled up to the same manufacturing techniques used for spray painting vehicles, meaning it could be easily applied to large, abstract architectural forms.
