  • Surface wrinkling reduces the performance of mixed-halide perovskite solar cells. Here, the authors identify that sequential nucleation of bromide-rich and iodide-rich domains results in compositional heterogeneity and subsequent wrinkling.

  • Interfacial engineering is key to ensure the long-term stability of perovskite solar cells. Research now shows that chiral molecules can both improve the mechanical stability of the interfaces and afford passivation of defects at the perovskite surface, making solar cells more tolerant to thermal cycling stress.

  • An improved device design for perovskite-based photovoltaic cells enables a certified power conversion efficiency of 25.2 per cent, translating to 80.5 per cent of the thermodynamic limit for its bandgap, which approaches those achieved by silicon solar cells.

  • Perovskite solar cells are still plagued by hysteresis, despite the good charge transport properties of the perovskite counterpart. Here, the authors dope the mesoporous TiO2scaffold with lithium to improve the transport properties of this other important component of solar cells, and reduce the hysteresis.

  • The efficiency of perovskite solar cells is limited by the performance of the hole-transport material, which extracts charges from the active layer. Here, a molecularly engineered hole transporter with performance comparable to spiro-OMeTAD is demonstrated.
