Metrics & MoreArticle Recommendations CONSPECTUS: Organolead halide-based photovoltaics are one of the state-of-theart solar cell systems with efficiencies increasing to 25% over the past decade, ascribed to their high light-absorption coefficient, broad wavelength coverage, tunable band structure, and excellent carrier mobility. Indeed, these optical characteristics are highly demanding in photocatalysis and photoluminescence (PL), which also involve the solar energy utilization and charge transport. However, the vast majority of organolead halides are ionically bonded structures and susceptible to degradation upon high-polarity protic molecules (e.g., water (vapor) and alcohol), which are often inevitable in many photochemical applications.Encapsulation is a commonly used stabilization approach by coating protective layers, avoiding the direct contact between organolead halides and polar molecules. However, this may partially hinder the light penetration to the inner hybrid halide

Layered organolead halides are an emerging class of self-trapped emitters, in which the unique corrugated structures are critical to afford out-of-plane distortions for self-trapping. However, the labile corner halide species...
