For years, a quiet inefficiency haunted the most common design of perovskite solar cells — electrons slipping away as heat at a boundary no one could quite fix. A research team has now resolved this decade-long impasse by reimagining the electron transport layer as a gradient rather than a uniform material, coaxing charges through before they are lost. The result is a certified 27.17% efficiency record, but the deeper achievement may be a new philosophy: that the interfaces between materials are not obstacles to be tolerated, but structures to be deliberately shaped.
