Steering perovskite precursor solutions for multijunction photovoltaics by Hu, S, Wang, J, Zhao, P, Pascual, J, Wang, J, Rombach, F, Dasgupta, A, Liu, W, Truong, MA, Zhu, H, Kober-Czerny, M, Drysdale, JN, Smith, JA, Yuan, Z, Aalbers, GJW, Schipper, NRM, Yao, J, Nakano, K, Turren-Cruz, S-H, Dallmann, A, Christoforo, MG, Ball, JM, McMeekin, DP, Zaininger, K-A, Liu, Z, Noel, NK, Tajima, K, Chen, W, Ehara, M, Janssen, RAJ, Wakamiya, A, Snaith, HJ

“…Multijunction photovoltaics (PVs) are gaining prominence owing to their superior capability of achieving power conversion efficiencies (PCEs) beyond the radiative limit of single-junction cells^1-8, where improving narrow bandgap tin–lead perovskites is critical for thin-film devices⁹. With a focus on understanding the chemistry of tin–lead perovskite precursor solutions, we herein find that Sn(II) species dominate interactions with precursors and additives and uncover the exclusive role of carboxylic acid in regulating solution colloidal properties and film crystallisation, and ammonium in improving film optoelectronic properties. …”

Hofstadter Physics and Composite Fermionic Phase in Moiré Systems by Ding, Shuhan

“…Building on this framework, we delve into the concept of composite fermions, particularly in the context of the fractional quantum Hall effect (FQHE). We extend Jain’s composite fermion theory and the Chern-Simons field theory to Moiré TMD systems, proposing the existence of an anomalous composite fermion liquid state at half-filling. …”

2D-3D perovskite memristor with low energy consumption and high stability for neural morphology calculation by Sun, Kaixuan, Wang, Qingrui, Zhou, Long, Wang, Jingjuan, Chang, Jingjing, Guo, Rui, Tay, Beng Kang, Yan, Xiaobing

“…Moreover, this perovskite-based artificial synapse has ultra-low power consumption due to the switchable p-i-n structure in organic-inorganic halide perovskites. Our finding highlights the immense application potential of the 2D-3D perovskite memristor in the future neuromorphic computing system.…”

Surface composition dependent ligand effect in tuning the activity of nickel–copper bimetallic electrocatalysts toward hydrogen evolution in alkaline by Wei, Chao, Sun, Yuanmiao, Scherer, Günther G., Fisher, Adrian C., Sherburne, Matthew, Ager, Joel W., Xu, Zhichuan Jason

“…Unfortunately, the principles that governs alkaline HER performance remain unclear and are still under debate. By studying the alkaline HER at a series of NiCu bimetallic surfaces, where the electronic structure is modulated by ligand effect, we demonstrate that alkaline HER activity can be correlated with either the calculated or the experimental-measured d band center (an indicator of hydrogen binding energy) via a volcano-type relationship. …”

Alternative credit scoring for the un(der)banked by Elrakabawy, S

“…My work contributes socially by improving access to finance for the un- and underbanked, as well as academically by filling gaps in research. A comprehensive empirical comparative demographic analysis of Company X's loan applicant base highlights social aspects (such as gender inequality) and emphasizes a lack and / or low access to finance. …”

Two Paths: Why States Join or Avoid China’s Belt and Road Initiative by Atkins, Eleanor, Fravel, M Taylor, Wang, Raymond, Ackert, Nick, Huang, Sihao

“…Although China’s motives for developing the Belt and Road Initiative (BRI) have been well studied, scholars have yet to comprehensively examine why states seek to join the initiative. We fill this gap by examining how and why states join the BRI. …”

Optical gain in ultrathin self-assembled bi-layers of colloidal quantum wells enabled by the mode confinement in their high-index dielectric waveguides by Foroutan-Barenji, Sina, Erdem, Onur, Gheshlaghi, Negar, Altintas, Yemliha, Demir, Hilmi Volkan

“…To achieve optical gain from such an ultra-thin nanocrystal film, hybrid waveguide structures partly composed of self-assembled layers of CQWs and partly high-index dielectric material are developed and shown: in asymmetric waveguide architecture employing one thin film of dielectric underneath CQWs and in the case of quasi-symmetric waveguide with a pair of dielectric films sandwiching CQWs. …”

Local climate action from the middle-out: the social potential of craft guilds to facilitate low-carbon installations in Germany by Wehden, S, Janda, KB, Jansen, J, Creutzig, F

“…However, research on effective governance arrangements targeting this ‘installation bottleneck’ is limited. To fill this gap, we adopt a Middle-Out Perspective (MOP) and use rich qualitative data including in-depth interviews to study the role of craft guilds within Germany's low-carbon transition, particularly in rooftop photovoltaic and heat pump installation. …”
