Flexible Solar Cells Could Be Woven Into Clothes
Researchers at the National Renewable Energy Laboratory in Golden have achieved a reasonably high efficiency in flexible perovskite solar cells, making them stronger. In the future, they can be placed on any surface, even clothes..
Unlike classic silicon panels, perovskite wafers do not require high-precision processing and are applied to the substrate like typographic ink, which makes production easier and cheaper. These photocells have a less rigid shell, so they can be made as thin films that can cover office windows, vehicles, electronics and clothing..
In less than 10 years of studying this type of material, the researchers were able to achieve the same level of efficiency for converting light into electricity as in silicon cells (22.5%). However, the advantage of perovskites is that they can be placed in multiple layers, each of which uses a specific color format. This combination can improve conversion efficiency up to 40% or more..
By themselves, perovskite solar cells are quickly destroyed by oxygen and moisture, but today protection methods have been developed that increase the stability of the crystal structure. According to the researchers, a new type of photovoltaics in the near future will be able to radically change our energy system, especially in the development of microgrids, which are already beginning to be tested..
Scientists are also working on other clean energy ecologists, such as the fusion reactor. Recently at one of these experimental «artificial suns», were able to reach plasma temperatures up to 100 million degrees °FROM.
