Reinforcing self-assembly of hole transport molecules for stable inverted perovskite solar cells. (https://pubmed.ncbi.nlm.nih.gov/38484063/)

These scientists wanted to make solar cells that can convert sunlight into electricity more efficiently and last a long time. They discovered that using a special layer called a self-assembled monolayer (SAM) can help improve the solar cells. However, they found that the SAM can come off if it's not attached properly.

To solve this problem, the scientists used a method called atomic-layer deposition to create a surface that can hold the SAM tightly in place. They also used a different type of SAM that sticks to the surface really well. With these improvements, the solar cells they made were able to convert sunlight into electricity with an efficiency of 24.8% and 23.2%, which is really good.

They also tested the solar cells to see if they could still work well after being exposed to harsh conditions like heat and humidity. The results showed that the solar cells were still working at almost the same efficiency even after being tested for a long time. This means that the solar cells they made are not only efficient but also durable.
