Mixed cation perovskites, [HC(NH2)2]xCs(1−x)PbI3, (FAxCs(1−x)PbI3) with x = 0.8 achieve high solar cell power conversion efficiencies (PCEs) while exhibiting long-term stability under ambient conditions. In this work, we perform density functional theory (DFT) calculations, first-principles molecular dynamics (MD) simulations, solid-state nuclear magnetic resonance (NMR) and X-ray powder diffraction (XRD) measurements aimed at investigating the possible phase stability of Cs+-rich FAxCs(1−x)PbI3, mixed-cation materials as potential candidate for tandem solar cell applications.

Abstract

Mixed cation perovskites, [HC(NH2)2]xCs(1−x)PbI3, (FAxCs(1−x)PbI3) with x = 0.8 achieve high solar cell power conversion efficiencies (PCEs) while exhibiting long-term stability under ambient conditions. In this work, we perform density functional theory (DFT) calculations, first-principles molecular dynamics (MD) simulations, solid-state nuclear magnetic resonance (NMR) and X-ray powder diffraction (XRD) measurements aimed at investigating the possible phase stability of Cs+-rich FAxCs(1−x)PbI3, mixed-cation materials as potential candidate for tandem solar cell applications.
