Two years. This is the target date in Japan for the market launch of new ultra-thin perovskite solar panels which will also be ultra-flexible. So much so that it can be deployed on the body of a vehicle and thus overturn solar cars.

the a d The Japanese media appear to be the end (or the starting point) of a project undertaken, hand in hand, by Panasonic and Sekisui Chemical under the leadership of Toin University professor of Tokohama, Tsutomu Miyasaka. With the creation, the expert leaves for a Nobel, suggests the Japanese press.

Whether or not he receives the award, the work that began in 2009 appears to be nearing completion, with the development of perovskite cells measuring 20 × 20 centimeters. The size here is deceptive, as the idea is that they can be put together without any problems, to create long sheets that can be used for endless commercial uses. Lightweight, flexible and as thin as photographic film, this technology of the future could chip away at conventional silicon panels on roofs, walls, columns or, of course, the exterior of vehicles.

Another point in favor of extending these cells when their marketing is confirmed will be their lower cost. Unsurprisingly, perovskite is considered by many experts around the world to be one of the materials of the future, precisely because of the savings it could mean for the production of technologies for the use of clean energy.

But, in addition to the cost, the solutions that the Japanese experts are working on also aim to stand out in terms of efficiency. This is where much of the current effort is turning, with the target that the technology can achieve at least 20% efficiency. This is not a little, given that they are still far from this percentage, and the world records for this material are around 24%.

The robustness of the mechanism is another crucial aspect, especially if, as expected, it targets the automotive sector among its market niches. In order not to click at this point, from Sekisui Chemical the cell has been covered to prevent deterioration as much as possible and, therefore, extend its useful life by at least a decade. It is about half that of silicon cells, although it is true that the cost of production is also halved compared to these. In addition, this Japanese government-backed breakthrough, if it stands out in anything, is for its potential to mark a before and after by making almost any place suitable for the capture of solar energy.
