摘要：

At present, the cost-effective synthesis and stability are major concerns for perovskite halide, which are high-efficient light absorbing solar cell materials. In this work, the cesium lead halides CsPbX3 (where, X=I and Br) were synthesized by simple but unique cold sintering method. The structural (XRD and Raman), microstructural (SEM), electronic (XPS) and optical studies (UV-Visible spectra) revealed that the samples synthesized are in the single phase with Pnma symmetry. The thermal stability of the samples synthesized was explored by estimating G and S. A negligible change in crystal structure and band gap of the samples is observed after 100days of synthesis showing the stability of samples in the ambient condition. Along with structure-property correlation, the thermo-optical correlation for halide materials has also been established. A comparative of the band gap (on the basis of synthesis technique) suggests the samples synthesised by cold sintering are at par with other synthesis technique.
