Using clean, free power from the sun to run our cars sounds like a revolutionary answer to a lot of our current problems, but will it ever really work?
Ever heard of solar paint? Let’s explore this innovative technology. Could it be the next generation of solar energy production, or is the idea too good to be true?
An innovative 3D solar-cell design with a radically different architecture which drives down the costs of cell manufacture may define the future of renewable energy as it potentially reduces optical losses within a device, according to UK scientists.

According to the University, this development could potentially make the manufacture of perovskite solar cells more efficient, as the process would require fewer batches of more stable material to be produced, saving time, reducing material waste and also allowing device yield and efficiency to be optimised.
Perovskite solar cells are fabricated using simple solution-based techniques similar to those used in the printing industry and companies looking to commercialise perovskite solar cells are thinking about the best ways to manufacture at high volume.
In a statement, Professor David Lidzey, from Sheffield University’s Department of Physics and Astronomy, said: “If a company cannot produce large volumes of precursor solutions and be able to rely on them performing consistently, it further complicates the manufacturing process. We have shown that this problem can be side-stepped by storing such materials at low temperature.”
