Predictive Structure-Property Design Rules for Quasi-2D Dion-Jacobson Sn-Based Perovskites

JAJuan Camilo Alvarez-QuicenoJQJuan Camilo Alvarez QuicenoSJSantiago Gómez Jaramillo

Key Points

  • This research aims to uncover design rules that improve the stability of lead-free tin-halide perovskites by addressing the instability of Sn2+.
  • Utilized predictive modeling techniques for structure-property relationships
  • Analyzed quasi-two-dimensional Dion–Jacobson (DJ) structures for potential stability improvements
  • Explored various compositions and configurations of tin-based perovskites
  • Identified key structural features that enhance the stability of quasi-2D tin-based perovskites
  • Demonstrated a significant reduction in Sn2+ instability with specific structural modifications
  • Provided guidelines for the design of future lead-free perovskite materials

Abstract

The Sn^2+ instability is the critical bottleneck preventing the widespread implementation of lead-free tin-halide perovskites. While quasi-two-dimensional (Q2D) Dion--Jacobson (DJ) structures offer the leading stability solution, the field's reliance on. . .
