Mechanochemical Synthesis, Electronic Structure, and Photovoltaic Potential of Lead-Free Hybrid Halocobaltates (CH3NH3)2CoX4 (X = Cl, Br)
Here, (CH3NH3)2CoCl4 and (CH3NH3)2CoBr4 were prepared via a solvent-free mechanochemical route and characterized by powder X-ray diffraction, electron microscopy, X-ray photoelectron spectroscopy, magnetic susceptibility, and thermal analysis. Both compounds crystallize in the monoclinic P21/c space group and exhibit p...
