Abstract: In organic-inorganic hybrid perovskite solar cells (PSCs), hydrogen defects introduce deep-level trap states, significantly influencing non-radiative recombination processes. Those defects are primarily observed in MA-PSCs rather than FA-PSCs. As a result, MA-PSCs demonstrated a lower… read more here.

Abstract: Abstract This paper assesses the role of doping on the hydrogen permeability and electronic properties of α-Al2O3. Formation energies of intrinsic and extrinsic defects in α-Al2O3 were calculated using density functional theory. Using these energies… read more here.
