Influence of Bi doping on physical properties of lead halide perovskites: a comparative first-principles study between CsPbI3 and CsPbBr3
We study the effects of Bi doping on the physical properties of CsPbX3 (X = I or Br), promising active materials in application to the solar cell, using first-principles calculations with the hybrid functional. In both CsPbBr3 and CsPbI3, we find that excess electrons introduced by Bi replacing Pb (...
