  • Although the performance of sensitized TiO2 solar cells has increased considerably over recent years, Leijtens et al. show that they are susceptible to a light-driven instability that degrades their performance over time. They go on to show that this instability can be overcome in mesoporous TiO2-free devices.

  • Low bandgap tin–lead perovskites are crucial to making efficient all-perovskite tandem solar cells but have so far shown poor stability. By removing the hole transport layer and improving film morphology, Prasanna et al. demonstrate a low-gap perovskite solar cell that is stable for 1,000 h under heat, light and atmospheric conditions.

  • Visual evidence for photo-induced ionic migration in perovskite films without contacts is lacking. Here, the authors use a unique combination of confocal photoluminescence microscopy and chemical imaging to correlate the local changes in photophysics with composition in CH3NH3PbI3films under illumination.

  • Perovskite solar cells can complement silicon photovoltaics in multijunction devices. Here, the authors optimize light harvesting in monolithic perovskite-on-silicon devices and fabricate a certified 23.6% efficient, 1 cm2 tandem solar cell with a perovskite device that withstands damp heat tests.

  • Perovskites, with their wide bandgap range, are good partners for both commercial and novel photovoltaic technologies in multijunction solar cells. Here, McGehee and co-workers review recent material and device developments and highlight future challenges and opportunities for perovskite-based tandems.
