Stability Diagrams, Defect Tolerance, And Absorption Coefficients Of Hybrid Halide Semiconductors: High-Throughput First-Principles Characterization

On the basis of the screened 29 hybrid halide compounds from our prior study [Y. Li and K. Yang, Energy Environ. Sci. 12, 2233-2243 (2019)], here, we reported a systematic computational study of the stability diagram, defect tolerance, and optical absorption coefficients for these candidate materials using high-throughput first-principles calculations. We took two exemplary compounds, MA(2)SnI(4) and MA(3)Sb(2)I(9), as examples to show the computational process, and they are discussed in detail. This work is expected to provide a detailed guide for further experimental synthesis and characterization, with the potential to develop novel lead-free optoelectronic devices.
