Low-bandgap tin–lead perovskites can boost solar cell efficiency but degrade quickly due to tin oxidation. Here the authors add proton-scavenging additives that stabilize inks for over 300 days, enabling 24.06% single cells and 29.56% certified tandem efficiency.

We developed PTFF, a bio-based encapsulation polymeric material that is compatible with existing hot-pressing processes, is non-destructive to perovskites, and is closed-loop recyclable.
