  • The benign nature of defects in lead halide perovskites is widely regarded as the basis for their outstanding optoelectronic properties. Here Righetto et al. overthrew this perception, revealing the defects’ surprising potency to hot carriers and devised a strategy to suppress them.

  • Hybrid halide perovskites have demonstrated promising performance as solar cells. It is now reported that these solution-processed materials are also suited to lasing applications, because of the high optical gain and stable amplified spontaneous emission they show in the visible spectral range.

  • Spin-information transport or transfer is essential for spintronics applications and often relies on high purity and quality materials. Here, the authors report on the defect-tolerant solution-processed Ruddlesden–Popper halide perovskites, where a spin propagation length of 600 nm was achieved via spin funneling.
