Saudi Arabia: New innovations are underway to increase the efficiency of solar cells around the world, and now an important development has come out in this regard, under which
The efficiency of perovskite, silicon sandwich (tandem) solar cells has been dramatically increased by adding metal fluoride.
Experts from King Abdullah University of Science and Technology created a solar cell consisting of several layers of perovskite mineral and conventional silicon.
A thin layer of metal fluoride is applied in between. Over the past several years, the efficiency of double-layer tandem solar cells has increased and thus the scope of research on them has increased. However, the addition of metal fluoride can now make such solar cells four months old.
In this context, the scientists of Jamia have added a thin layer of magnesium fluoride to the perovskite, which increased the emission of electrons from the perovskite. In this way, experimentally, 50 milliwatts more power was obtained in a solar cell. Thus, the efficiency of the new solar cell made reached 29.3%. On the other hand, the process remained stable and did not change over time.
