Halide Phase Segregation in Wide‐Bandgap Perovskite Photovoltaics: Mechanisms, Advanced Characterization, and Rational Mitigation Strategies Toward Stable Solar Cells

Carbon Neutralization, Volume 5, Issue 3, May 2026.
Overview of halide phase segregation in mixed‐halide perovskites: covering fundamental mechanisms, spatiotemporal characterization insights, and mitigation strategies for enhanced stability. ABSTRACT Mixed‐halide (I/Br) wide‐bandgap perovskites have emerged as promising top‐cell candidates for tandem photovoltaics due to their tunable bandgap and ...

Rearrangements of Acyl, Thioacyl, and Imidoyl (Thio)cyanates to Iso(thio)cyanates, Acyl Iso(thio)cyanates to (Thio)acyl Isocyanates, and Imidoyl Iso(thio)cyanates to (Thio)acyl Carbodiimides, RCX-YCN ⇌ RCX-NCY ⇌ RCY-NCX ⇌ RCY-XCN (X and Y = O, S, NR′)

, 2016
Two types of rearrangements have been investigated computationally at the B3LYP/6-311+G­(d,p) level. The activation barriers for rearrangement of acyl thiocyanates RCO–SCN to the corresponding isothiocyanates RCO–NCS are 30–31 kcal/mol in agreement with ...
