~ ~ > < P > In addition, most solar cells are produced in China, where there is a rich silicon. In view of this, American manufacturers needed a new material that would be available in the US.

< p >“We develop technologies that can be easily produced without spending a lot of money on expensive equipment”, & mdash; said Juan Pablo Correa-Baena, Associate Professor of the School of Materials Studies and Engineering.

< P > As an alternative, a Silicon Research Group led by Correa Baane proposed Perovskit crystals. Perovskit is also effective as silicon, but its service life is 95% smaller than in silicon. The material is particularly sensitive to hot summer temperatures and can be decomposed before the solar panel pays off.

< p > Trying to solve this problem, American scientists have found a way to stabilize the perovskitny solar elements that are built as a battery. They have one positive and one negative electrode and the perovskitic element is clamped between them.

< P > Before placed the positive electrode in the upper part of the element, the researchers have exposed the perovskit exposure to titanium gas in a mild vacuum. This process, known as vapor -phase infiltration, introduces titanium into the top layer of the solar element. Thus scientists made one of the layers stronger and more resistant to high temperatures.

< p > “Introducing Titan, we can prevent the degradation process and then try the solar battery on the roof or anywhere else”, & mdash; noted Correa-Baane.

< P > The technology of stabilization, developed by the team, eliminates the main drawback of perovskitic elements, making them more viable for long -term use. The publication believes that this breakthrough can contribute to the introduction of renewable energy in the US.
