This study investigates how polyvinylpyrrolidone (PVP) affects cesium-based lead halide perovskites, focusing on phase, morphology, film stress, and ion concentration during aging. Using PVP in CsPbI3 enhances film stability by inducing compressive stress, with negligible impact on bandgap and ion behavior under aging conditions.

How Paios was used

The all in one characterization tooll, Paios, was used to analyse ion concentration with transient current measurements.
