One-Step Formation of 2D/3D Perovskite Heterojunction via Ligand Intercalation and Facet Engineering for Efficient Perovskite Solar CellsOA
Two-dimensional/three-dimensional(2D/3D)perovskite heterojunctions at the contact interfaces have been proven to enhance the stability and power conversion efficiency(PCE)of perovskite solar cells(PSCs).The 2D/3D bilayer is typically formed via a solution post-treatment onto the 3D perovskite,where the 2D layer’s dimensionality depends on the ligand size and its reactivity.Despite their stability,long-chain ligands typically form 2D perovskites with low dimensionality(n=1,2)which feature poor charge conductivity and mobility.Here,we propose an in situ fabrication method incorporating long-chain oleylammonium(OlyA+)ligands directly into the perovskite ink.This approach forms 2D perovskite with higher dimensionalities(n≥3)with enhanced(001)crystal facet orientation of the 3D film,improved energetic alignment,charge extraction,and structural stability.The fabricated inverted PSCs with 1.55 eV bandgap achieved a maximum PCE of 26.22% for small area and 24.6% for 1cm^(2) devices,as well as 21.1%for mini-modules(6.8 cm^(2)).Additionally,the PSCs with in situ formed 2D/3D perovskite heterojunctions retained 90% and 80% of their initial PCE after 1200 h photothermal stability and 1050 h outdoor testing,respectively.Our one-step strategy produces uniform and stable 2D/3D perovskite heterojunctions with enhanced passivation capability,overcoming the limitations of conventional sequential methods and offering a promising and effective approach for highly stable and efficient PSCs.
