Carrier Localization in Pnictogen-Based Chalcohalides from Defect-Bound Hot Polarons
Xiaoyu Guo, Junzhi Ye, Cibrán Lopez Alvarez +19
Pnictogen-based solar absorbers have gained prominence as promising nontoxic and stable alternatives to lead-halide perovskites (LHPs), but are severely limited by carrier localiza…
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…
Breaking the 800 mV open-circuit voltage barrier in antimony sulfide photovoltaics
Jiacheng Zhou, Xinwei Wang, Tianle Shi +6
Sb2S3 is a promising material for low-toxicity, high-stability next-generation photovoltaics. Despite high optical limits in efficiency, progress in improving its device performanc…
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…
