The new generation of perovskite solar cells

Solar cells for power generation are a viable economic alternative today to polluting alternatives based on fossil fuels, and the best thing is that each year their prices continue to drop, making their energy future better and better.

But today’s solar cells are based on silicon and have a low return on energy from the sun. They only take advantage in the order of 15% of the energy received.

And therefore researchers have been looking for alternatives for many years, and one of them was the use of perovskite cells that can get to transform 25% of the energy received from the sun, but they had the problem that these cells decomposed with the passage of time.

As the technology was very promising, there have been many people researching how to avoid this deterioration, and there is already an Australian team that claims to have achieved it, and they have published their results in the journal Science.

According to these people, they cover the perovskite cells with a very thin and cheap polymer protection sheet, so that they have the necessary durability.

They have subjected the cells thus treated to the international environmental tests that an industrial equipment of these characteristics must pass, and they have successfully passed them. Therefore, they are not far from being able to take these types of cells to the serial production phase.

Solar energy is the one that presents the best alternatives for the future, since sunlight is available in all countries, and reception plates can be placed almost anywhere.

If the panels also continue to lower their prices and improve their energy profitability, they end up paying for themselves in less time, and therefore they are more used.

This is a positive circle in which we all win, and governments (and especially Spain) should promote this technology more.
