Halide Perovskites: Advanced Photovoltaic Materials Empowered by a Unique Bonding Mechanism

Matthias Wuttig et al.

Summary: Halide perovskites, such as ABX(3) compounds, are promising PV materials with favorable optoelectronic properties governed by the B-X bond. The unique metavalent bonding in halide perovskites, involving the sharing of one p-electron between adjacent atoms, results in pronounced optical absorption and small effective masses of charge carriers. Understanding this bonding mechanism provides insight for the design of efficient PV materials.

Facile strategy to synthesize cesium gold-based bromide perovskites: an integrated experimental and theoretical approach to study temperature-dependent structural and optical properties

Bhawna et al.

Summary: Three all-inorganic perovskite materials, CsAuBr4, CsAuBr3, and Cs2Au2Br6, were developed by systematically adding bromine ions to CsAuCl4. The structures of the compounds change from CsAuBr4 to CsAuBr3 to Cs2Au2Br6 as the concentration of bromine varies. The change in structures is associated with a valence state change of Au3+ to Au2+ to Au1+/3+. The compounds exhibit a variation in optical absorption, with a bandgap changing from 2.3 eV to 1.4 eV, making them suitable for visible light absorption. Cs2Au2Br6 shows sharp absorption edge and high absorption coefficient, indicating low disorders. The stability of CsAuBr4 and Cs2Au2Br6 among the three phases is confirmed. The study provides valuable insights into the properties and synthesis methods of all-inorganic perovskite materials.
