Conformal oxides decouple chemical stability and energetics at NiO x /perovskite interfaces

Nickel oxide (NiO x ) is a common hole transport layer (HTL) in perovskite photovoltaics, but the chemical reactivity of NiOx surfaces accelerates degradation when contacting perovskites. We developed an ultrathin, conformal tin oxide (SnO x ) interlayer to suppress interfacial r...
