Data-driven atomistic modelling of hybrid halide perovskite passivation
Laura-Bianca PaÅca, Henry J. Snaith, Volker L. Deringer
Molecular passivation of surface defects is key to improving the optoelectronic performance of hybrid halide perovskite materials, but the underlying atomistic mechanisms are incom…
Ligand Engineering for Precise Control of Ultrathin CsPbI3 Nanoplatelet Superlattices for Efficient Light-Emitting Diodes
Jongbeom Kim, Woo Hyeon Jeong, Junzhi Ye +17
Strongly-confined perovskite nanoplatelets (PeNPLs) offer opportunities not found in conventional isotropic nanocubes, especially in producing linearly polarized light, as well as…
Enhanced Stability and Linearly Polarized Emission from CsPbI Perovskite Nanoplatelets through A-site Cation Engineering
Woo Hyeon Jeong, Junzhi Ye, Jongbeom Kim +10
The anisotropy of perovskite nanoplatelets (PeNPLs) opens up many opportunities in optoelectronics, including enabling the emission of linearly polarized light. But the limited sta…
Diamine Surface Passivation and Post-Annealing Enhance Performance of Silicon-Perovskite Tandem Solar Cells
Margherita Taddei, Hannah Contreras, Hai-Nam Doan +13
We show that the use of 1,3-diaminopropane (DAP) as a chemical modifier at the perovskite/electron-transport layer (ETL) interface enhances the power conversion efficiency (PCE) of…
