Abstract

Quasi-2D perovskites strike a good balance between high performance and stability for solar cell applications. Formamidinium iodide doping could improve thermal stability and broaden optical absorption, yet tends to cause poor morphology. The work featured on this cover presents a new strategy to optimize the morphology, electronic properties, and humidity resistivity through mixed cation doping (MCD) and gradual deposition of methylammonium and formamidinium cations onto the perovskite layer. The underlying mechanism is revealed by interaction energies of cation mixtures in solution and computational analysis of perovskite structures. More information can be found in the Full Paper by Pongsakorn Kanjanaboos et al. on page 1280 in Issue 10, 2019 (DOI: 10.1002/cnma.201900189).
