is 32.5 percent. The paper reports on the improvements in silicon-perovskite tandem cells that have made this possible.
“Although our materials help achieve the highest efficiency, it is difficult to form another layer on top. After our previous paper in Science, we received a lot of attention and comments about how our materials act in different contexts. In the current paper, we show one way to address the problems,” said Dr Magomedov.
“In theory, electricity made by tandem solar cells would be cheaper because the additional materials used are cheaper. However, in practice, the final commercial product does not exist, the technological processes are not ready for mass production. Moreover, the cell itself, which is only being developed in laboratories so far, also raises unanswered questions. For example, not all materials are suitable for mass production, which means that alternatives have to be found,” Magomedov explained.
