Efficient NiOx Hole Transport Layers Enabled by Multifunctional MXenes for High‐Performance Tin‐Lead Perovskite Solar Cells

Advanced Functional Materials, EarlyView.
An efficient NiOx HTL is successfully prepared by introducing MXene as an additive without further surface modification to fabricate high‐performance FASn0.5Pb0.5I3 perovskite solar cells. The introduction of MXene contributes to improved conductivity of NiOx, better aligned at NiOx/perovskite interfaces, and enhanced quality of perovskite films ...

Stress-Corrosion Cracking

Corrosion, 1963
Stress-corrosion cracking facts and theories are reviewed, especially the phenomena found with stainless steels and with α-brass. Evidence is given that stress-corrosion "cracking" is not rupture of brittle metal. Rather, cracks propagate by rapid dissolution of their mechanically yielding advancing edges, while their static sides dissolve extremely ...
