Currently, the production of Energy solar it usually requires expensive and impractical installations. What if a painting could you change the facts? Behind this advance in the field of green energy, there is a technique that allows to apply cells photovoltaic to almost all types of surfaces.
Researchers at the University of Sheffield, in the United Kingdom, have developed cells photovoltaic They could be applied like a spray paint. Therefore, it would be possible in theory, to transform a whole range of products and surfaces into generators of energy. The idea of flexible solar panels is not new, but it takes time to materialize.
This new track brings another advantage: the coste manufacturing is less. While solar cells are usually composed of materials that require a lot of energy to manufacture (specifically silicon), the use of perovskite (an abundant mineral on Earth) would need much less.
All the cells They would be applied through a method that resembles that of painting a car or a graphic printing press: sprayers that would spread out several layers. Spending would be better controlled. The concept could easily be adapted to a production in series and become something more accessible.
Replacing the absorption layer of the light, essential in all cell PV, for a perovskite in the form of spray paint, the researchers have also improved the performance energetic.
