Abstract
The well-established application of APbX3 (wherein A = Cs or CH3NH3 and X = I, Cl or Br) into photovoltaic solar cells deal with a poor long-term stability due to the material hydrophilic nature and high ionic conductivity facilitating the interface degradation. Building 2D/3D multidimensional heterostructured system contributes to overcome the challenges in the photo-absorber layer by re…
