Chiral-structured heterointerfaces enable durable perovskite solar cells. (https://pubmed.ncbi.nlm.nih.gov/38781395/)

These scientists wanted to make solar cells that can last a long time even when it's really hot or humid outside. They found that the way different materials in the solar cells stick together can affect how well the solar cells work over time.

So, they created a special way for the materials in the solar cells to connect to each other using something called R-/S-methylbenzyl-ammonium. This made the connection between the materials strong but also flexible. They found that by arranging these materials in a specific way, they could make the solar cells more stable and able to keep working even when it's really hot or humid.

After testing these new solar cells by putting them through very hot and very cold temperatures, as well as high humidity, they found that the solar cells were able to keep working really well. In fact, they only lost a little bit of their power-conversion efficiency, which is how well they can turn sunlight into electricity. This means that these new solar cells could last a long time and still work great, even in tough conditions!
