DOI: 10.1002/smtd.202501325

Abstract: NiOx is widely used for hole-transporting layers in p-i-n-type perovskite solar cells (PSCs) due to its stability, wide bandgap (≈3.5 eV), and solution processability. However, during solution processing, oxygen exposure can induce non-stoichiometry, forming Ni≥3… read more here.

DOI: 10.1007/s00126-017-0739-3

Abstract: Arc magmas are more oxidized than mid-ocean ridge basalts; however, there is continuing debate as to whether this higher oxidation state is inherited from the source magma or developed during late-stage magmatic differentiation processes. Well-constrained… read more here.
