The first perovskite solar cells capable of operating for 30 years without replacement have been tested in the USA

Perovskite is an extremely promising mineral for the construction of solar panels.
However, the main problem with such products is their short lifespan.
Researchers at Princeton University in the U.S.
finally tested in the laboratory sample, capable of working without replacement up to 30 years in real conditions.Image source: Andlinger Center for Energy and the EnvironmentAlthough the main material for solar panels for decades has been silicon, in the last 15 years perovskite actively wrests its position.
Perovskite is just as effective as silicon, but it allows you to create less expensive, lighter and more flexible panels.
Nevertheless, perovskites are not very stable and rather short-lived in real-world applications.In the new study, Princeton scientists added a special intermediate layer, literally a few atoms thick, between the light-absorbing perovskite and charge-bearing layers to stabilize the design.
Although similar solutions have been proposed by various teams in the past, the new composition potentially keeps the solar cells alive for more than 30 years - the first solution in its class to cross the 20-year threshold.Image source: Andlinger Center for Energy and the EnvironmentWe are still only talking about experiments, however.
The researchers used an artificial aging chamber to evaluate the \"vitality\" of the panels, in which the elements were exposed to sunlight and temperatures ranging from 35 ° C to 110 ° C.
Extrapolating from the data obtained, the team concluded that under standard climatic conditions the new solution is capable of working for 30 years.
According to the scientists, the artificial aging chamber used will make it possible to test the stability of not only perovskite cells, but also any other solar cells.

Huawei sees prospects in developing its energy business

Sanctions by the U.S.
and its allies, as you know, have badly affected Huawei Technologies in terms of sales of smartphones and base stations for communication networks, but the Chinese giant is seeking new niches for further development, and supplies of modern equipment for the energy sector may become a way to save the company in the difficult current conditions.Image source: Huawei Technologies Last June, Huawei managed to separate into an independent structural unit of its business.
Originally, Huawei had to produce them to equip its own base stations with autonomous power supply, but now the corresponding solutions are supplied to a wide range of customers.
The interest in Huawei energy systems in the Asian region is very high, according to the company's representative.
While the revenue of Huawei Technologies as a whole decreased by 28.5 percent in 2021 under the burden of sanctions, the energy business showed a 30 percent revenue growth and it is going to maintain the same dynamics this year.
The unit employs about 6,000 people, and there are 12 research centers of the relevant profile scattered across China, Asia and Europe.
Huawei energy equipment is produced in China using components from different countries, but if necessary, the company is ready to organize the production of such products abroad as well.
Diversification of supply channels allowed the company to avoid a significant impact of lockdowns in China on its core business.
Huawei has high hopes for the upcoming migration to electric vehicles - the development of charging infrastructure will not do without the use of this brand's power generation equipment.
Currently, solar power plants in Singapore, Indonesia and Cambodia are actively using Huawei solutions, and the brand's profile products are in high demand in the region.
