  • The random orientation of spontaneously formed 2D phase atop 3D perovskites limits the performance of solar cells. Here, authors introduce a meta-amidinopyridine ligand with solvent post dripping to generate highly ordered 2D perovskites, achieving maximum efficiency of 26.05% for stable devices.

  • Batch-to-batch reproducibility of device performances is crucial for perovskite photovoltaics moving towards industrialization. Here, the authors show that commercial as-received C60 source materials may coalesce during repeated thermal evaporation processes, jeopardizing such reproducibility.

  • An independently certified power conversion efficiency of 32.5% for perovskite/silicon tandem solar cells is achieved through improved charge transfer at the amorphous indium zinc oxide interconnecting layer and reduced optical losses at the front and rear electrodes.

  • The implementation of low-dimensional perovskite capping layers is a promising strategy for enhancing the performance of perovskite solar cells; however, their thermal stability and reproducibility remain inadequately understood. This Review examines these underlying challenges, emphasizing ligand design and fabrication techniques to achieve high-quality, high-purity capping layers.
