  • The performance of perovskite-based solar cells has improved dramatically in recent years, yet surprisingly little is known about the details of how they work. Grancini et al. report results that suggest that their behaviour is dominated by the transport of free carriers rather than excitons.

  • The electron–phonon coupling is the key to understand optoelectronic properties in lead halide perovskites but it is difficult to probe. Here Batignani et al. observe two new phonon modes with impulsive vibrational spectroscopy providing the evidence of the polaronic nature of the photo-excitation.

  • Charge carriers in metal halide perovskites seem to be only marginally affected by defect-related trap states. Filippo De Angelis and Annamaria Petrozza suggest that the key to this behaviour lies in the redox chemistry of halide defects.

  • From displays to solar cells, the field of organic optoelectronics has come a long way over the past 50 years, but the realization of an electrically pumped organic laser remains elusive. The answer may lie with hybrid organic–inorganic materials called perovskites.

  • Despite their impressive performance, more efforts are required to develop industrially scalable perovskite solar cells from less toxic solvents. Towards that aim, this study presents the use of colloidal nanoparticle inks for room-temperature fabrication of CsPbBr3 solar cells.

  • Metal halide perovskites (MHPs) have substantial potential for solar cell applications. This Review critically assesses recent advances in elucidating the physical and chemical activity of defects in both high-bandgap and low-bandgap MHPs, and correlates it to performance and stability losses.

  • Understanding of defect physics in perovskite-halide semiconductors is essential to control the effects of structural and chemical defects on the performance of perovskite solar cells. Petrozza and Ball review the current knowledge of defects in these materials.
