KPb2Cl5
KPb2Cl5 is a thermodynamically stable, wide-gap insulating halide compound used in specialized optical and materials research applications.
About KPb2Cl5
KPb2Cl5 is a thermodynamically stable inorganic halide that exists securely on the convex hull. Its electronic character is defined by a wide-gap insulating nature, which distinguishes it from the more conductive or semiconducting members of the halide perovskite family often utilized in light harvesting. This compound is primarily valued for its structural robustness and potential utility in specialized optical applications where insulating properties are required. Its presence in structural databases highlights its well-defined crystalline arrangement and chemical reliability for materials research. The material serves as a stable host or component in systems where chemical durability is prioritized over high charge-carrier mobility. By maintaining a stable configuration, it provides a reliable foundation for exploring the intersection of halide chemistry and insulating material science.
Key Properties
Cross-validated computational properties for KPb2Cl5, aggregated across 3 databases.
Band GapEnergy needed to move an electron from the valence band to the conduction band. Lower or zero values tend to behave more metallic; larger gaps are more insulating or semiconducting.
Energy Above HullThermodynamic distance from the most stable set of competing phases. 0 eV/atom is on the convex hull; small positive values may still be experimentally accessible.

How It Compares
Within the halide perovskite photovoltaics class.
Unlike the highly active photovoltaic materials in its class such as CsPbBr3 or CsSnI3, which are characterized by their narrow-gap semiconducting behavior and high optoelectronic sensitivity, KPb2Cl5 functions as a wide-gap insulator. While its siblings are frequently studied for their ability to generate and transport charge carriers in solar cells, KPb2Cl5 occupies a distinct niche where its insulating nature and thermodynamic stability are leveraged for applications requiring dielectric performance rather than active light conversion.
