Double-side 2-dimensional/3-dimensional heterojunctions for inverted perovskite solar cells. (https://pubmed.ncbi.nlm.nih.gov/38382650/)

These scientists wanted to make solar cells more efficient and stable. They found that there were some problems at the top and bottom parts of the solar cells that were affecting how well they worked. So, they decided to use special long alkyl-amine molecules to make a new type of material called two-dimensional perovskites. These new materials helped to fix the issues at the top and bottom of the solar cells.

They also discovered that these special molecules could interact with the surface of the solar cells in a way that made them even better. By using these molecules, they were able to make the solar cells work really well, even when they were exposed to high temperatures and lots of sunlight.

In the end, the scientists were able to make solar cells that could convert sunlight into electricity with a very high efficiency of 25.6%. And even after being tested for a long time under tough conditions, the solar cells still worked really well, keeping 95% of their initial efficiency.
