Dual-Function Interface Engineering of SnO

Summary: Imagine trying to build a better, cheaper solar panel. Scientists are working on a new type called "perovskite" solar cells, which are super efficient at making electricity but can break down quickly over time. To fix this problem, researchers added a special chemical called PEI to one of the cell's layers (SnO). This chemical acts like a super-glue and a protective shield all in one! It helps the solar cell make more power and last much longer. This big step could help bring these amazing new solar panels to our homes very soon.
