Theoretical investigation of the electronic structure and anisotropic optical properties of quasi-1D Sb2Se3 photovoltaic absorber materials

Sb 2 Se 3 is a nontoxic, environmentally friendly photovoltaic absorber material with both a narrow bandgap and high absorption coefficient. The optical properties of Sb 2 Se 3 crystals are theoretically studied herein using first-principles methods. The crystal structure, electronic structure, diel...
