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…
Rapid Atmospheric Vapor Deposition of H:In2O3 Transparent Conducting Oxide Thin Films
Xiaoyu Guo, Hae-Jun Seok, Eilidh L. Quinn +14
Transparent conducting oxides (TCOs) are essential for the optoelectronics industry, but there is a critical gap in cost-effective methods to rapidly deposit low sheet resistance,…
Circularity in Perovskite-Based Tandem Photovoltaics for Terawatt-Scale Deployment
Abderrahime Sekkat, Shiling Dong, Jenny Baker +4
As photovoltaics (PVs) scale from one to multiple terawatts over the next decade, ensuring sustainable deployment is urgently required. Crystalline silicon (c-Si) PVs, the current…
Band-Like Transport and Cation Off-Centring in Ag/Bi-Based Solar Absorbers
Yi-Teng Huang, Yixin Wang, Georgia Fields +19
Ag(I)-Bi(III)-based semiconductors have gained substantial attention as nontoxic, stable alternatives to lead-halide perovskites for optoelectronics, but are widely limited by carr…
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…
