Homogeneous crystallization and buried interface passivation for perovskite tandem solar modules. (https://pubmed.ncbi.nlm.nih.gov/38386724/)

These scientists wanted to make solar cells that could capture more sunlight and convert it into electricity. They found that it was difficult to make these solar cells because the materials they were using were not forming properly and had some imperfections.

To solve this problem, the scientists added a special ingredient called aminoacetamide hydrochloride to the materials they were using. This ingredient helped the materials to form better and fixed any imperfections. They then coated these materials onto a surface using a special method called blade-coating.

After all this hard work, they finally made a solar cell that was able to convert sunlight into electricity very efficiently. This solar cell had a special power conversion efficiency of 24.5%, which means it could produce a lot of electricity from the sunlight it captured. It was a big success for the scientists!
