Abstract

Antimony sulfide (Sb2S3) has gained extensive attention in solar cells due to their potential as a low-cost and earth abundant absorber material. In solar cell absorber, the optoelectrical properties such as energy band gap and absorption coefficient of Sb2S3 play an important role, which have strong relationships with their crystal structure, lattice parameter and crystallite size.

Hence in the present investigation, Sb2S3 powder samples were exposed to biofield treatment, and further its physical, structural and spectral properties are investigated. The particle size analysis showed larger particle size and surface area after treatment. X-ray diffraction (XRD) analysis revealed polycrystalline orthorhombic structure with superior crystallinity in treated Sb2S3 along with significant changes in the lattice parameters, which led to changes in unit cell volume and density. XRD data analysis indicates that crystallite size was increased by around 150% in treated sample. In FT-IR spectra, strong absorption band was observed at 400-700cm-1, which confirms the presence of Sb2S3. Further, the absorption peak intensity in IR spectra was significantly reduced after treatment that was probably due to change in metal sulphur dipolar interaction.
