A new material for solar panels with record efficiency has been created in Russia

Hello dear guests and subscribers of my channel. Today I want to tell you about the unique development of Russian scientists, which will allow creating new solar panels with record efficiency. So let's go.

Solar energy problems and unique material

The development of an innovative material for photovoltaics was carried out by a research group from the St. Petersburg State Electrotechnical University "LETI".

And, according to the developers, their new material is quite capable of increasing the efficiency of solar panels to maximum (record) values.

You all know very well that solar energy is an extremely important part of the so-called green energy. Developments to improve existing ones and create new batteries have been going on for more than a decade, and according to In fact, modern multi-junction solar cells in terms of efficiency are already approaching their theoretical the ceiling.

Therefore, now the main forces are thrown in order to create and work out the most efficient and cost-effective algorithm for the production of solar panels.

How the new material was obtained

The technology for obtaining a new material is based on the use of silicon substrates, which are formed due to combining atomic layer deposition technology at the very start of production, and then using the gas-phase method epitaxy.

The main feature of the technology lies in the fact that the engineers decided to abandon the annealing, which is necessary to remove the oxide, at temperatures from 900 to 1000 degrees Celsius.

And they used a completely new approach and reduced the annealing temperature to 600-750 degrees, at which the epitaxial growth of GAP on Si substrates occurs. And further plasma-chemical deposition was carried out at a temperature of 380 degrees Celsius.

Due to this approach, it was possible to significantly improve the quality of the layers and reduce the degradation manifestations of the A3B5 layers.

What does this discovery give

The creation of such a material will allow in the future to create even more efficient solar panels at lower prices, which will lead to more widespread use of green energy and will undoubtedly have a beneficial effect on the overall environment, as it will reduce carbon emissions in atmosphere.

The scientists shared the results of the work done on the pages of the journal Physica Status Solidi (a) - applications and materials science.
