Rapid Characterization of Organolead Halide Perovskites
Organolead halide and mixed halide perovskites (CH3NH3PbX3, CH3NH3PbX3–nYn, X and Y = Cl–, Br–or I–), are promising materials for photovoltaics and optoelectronic devices but phase segregation halide ion speciation in mixed halide perovskites remain a challenge. Here we show that both fast MAS and DNP-enhanced solid-state NMR spectroscopy can increase sensitivity while reducing data acquisition time.
