Scientists University of Sheffield (UK) have created a spray paint that can turn any surface into a solar panel. As explained to the experts, this achievement has been achieved by working with the perovskite , a mineral that has the ability to absorb light and believe that applying spray could reduce the cost of renewable electricity .

The mineral perovskite is mainly made of calcium titanate and found in deposits throughout the world. Was discovered over 150 years ago but has only recently that scientists have begun to investigate its use as a replacement solar panel silicon semiconductor.

Sheffield team has the method previously used spray paint to produce solar cells using organic semiconductors, but the incorporation of the perovskite is a breakthrough.

Experts emphasize the success of this research, since this mineral It is much cheaper to obtain and process the silicon also layer light absorption can be incredibly thin-about 1 micrometer, compared to at least 180 microns of silicon required.

For the team that carried out the work, these benefits of your product make it “a solution to the real world” and believe they can be generalized in a short time in the industry.

Similarly, stressed that the solar panels made with this spray have an efficiency of up to 20% from a thin layer of perovskite. The average efficiency silicon cell panels is 25%.

Scientists also point to the “breakthrough” which is the process of applying perovskite with spray , thereby creating solar panels in cars or mobile devices that do not have completely flat surfaces and do not accept the standard mounting solar panels.

In fact, photovoltaic cells can be sprayed in a similar manner as painted cars during manufacture. This means that solar cells could be implemented quickly and efficiently in a process of industrial production in large quantities.

When applied in this way, it is possible to further simplify the application process and reduce the costs of manufacture of photovoltaic cells.
