Pb clustering and PbI2 nanofragmentation during methylammonium lead iodide perovskite degradation
Methylammonium lead halide perovskites have great potential for optoelectronic applications but are prone to degradation. Here the authors show that degradation can occur through clustering of Pb containing defects at the grain boundaries while concurrent formation of PbI2 blocks further reactions,...

| Sumario: | Methylammonium lead halide perovskites have great potential for optoelectronic applications but are prone to degradation. Here the authors show that degradation can occur through clustering of Pb containing defects at the grain boundaries while concurrent formation of PbI2 blocks further reactions, suggesting a strategy for passivation. |
