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

These scientists wanted to make solar cells more efficient and durable. They found that defects in the material used in solar cells were causing problems. So, they came up with a way to fix these defects using special molecules called long alkyl amine ligands.

These molecules were able to make the material in the solar cells stronger and more stable. They used the alkyl amine ligands to create a special type of material that made the solar cells work better. They also found that these molecules could interact with other parts of the solar cell to make sure everything worked smoothly.

After making these improvements, the scientists tested the solar cells and found that they were able to convert sunlight into electricity with an efficiency of 25.6%. This means the solar cells were really good at turning sunlight into power. Even after testing the solar cells for a long time under harsh conditions, they still worked really well. This is a big step forward in making solar energy more reliable and efficient!
