Russian scientists have managed to improve the efficiency of perovskite solar panels

The development of new and improvement of existing technologies for converting sunlight into electricity is ongoing around the world. But not every research group achieves significant success. But Russian scientists from NUST MISIS, with the support of their Italian colleagues, managed to significantly increase the efficiency of perovskite solar panels. And how they did it, I'll tell you now.

Why exactly perovskite

But first, I want to say a few words about why many scientists are working so closely with perovskite. The point is that perovskite is currently the most promising material for solar panels in the near future.

And the reason is this: on its basis, it is quite possible to produce the thinnest and at the same time multilayer solar panels, which can be easily applied to almost any surface and thus turn, for example, the walls of houses into sunny panels.

Scientists also note that perovskite panels can be produced by the so-called jet method without the use of expensive vacuum installations and similar expensive equipment. That is, perovskite panels are banally cheap and effective. But back to the new and, as it turned out, quite successful experiments of Russian engineers.

Successful experiments of Russian scientists

The aim of the next experiment was to increase the efficiency of energy production. For this, it was decided to add a special additive, MXenes, to the working solution for applying films.

This additive is a two-dimensional titanium carbide with increased electrical conductivity. These elements are obtained by etching and peeling off atomically thin layers of pre-deposited aluminum onto multilayer hexagonal carbides and nitrides. Moreover, the whole process is not only simple, but also cheap.

So, as a result of adding such an impurity, solar panels were obtained, the efficiency of which turned out to be higher than pure (without impurities) analogs, by no less than 2% and amounted to more than 19%.

In addition, due to the addition of impurities, it was also possible to increase the control over the concentration of defects in the cell structure, which also contributes to an increase in the efficiency of collection of the photo flux.

As the engineers note, the modification proposed by them is easily scalable and practically does not require changing the existing technologies for the production of solar panels. This means that it can be introduced into production in the shortest possible time.

Scientists have shared the results of their work on the pages of NANO ENERGY magazine.
