Enhancing the stability of perovskite solar cells through functionalisation of metal oxide transport layers with self-assembled monolayers

•Interface engineering with the use of SAM’s is a promising method for stability.•Perovskites films and devices were used for stability tests.•Stability tests were performed with light and temperature combined.•Perovskites films and devices degraded faster without SAM’s.•Self-Assembly monolayers increased longevity onto Perovskites films and devices.
