Chia PRX Energy 2, 013001 (2023) – Published 2 February 2023 | A combination of transient spectroscopy techniques provides an estimate of the time-resolved effective carrier mass and carrier-phonon coupling constant in a photovoltaic absorber, here applied to lead-halide perovskites. | | | | | | Nicholas Werren, Will Brown, and Erik M. Gauger PRX Energy 2, 013002 (2023) – Published 9 February 2023 | A theoretical study of bio-inspired ring systems demonstrates optical ratcheting as a means to enhance efficiencies of solar energy harvesting devices. | | | | | | Cristina Grosu, Chiara Panosetti, Steffen Merz, Peter Jakes, Stefan Seidlmayer, Sebastian Matera, Rüdiger-A. Eichel, Josef Granwehr, and Christoph Scheurer PRX Energy 2, 013003 (2023) – Published 1 March 2023 | Unexpected experimental and computational evidence of spontaneous lithium overintercalation challenges the currently accepted upper capacity limit of graphite battery anodes. | | | | | | Samah Akel, Ashish Kulkarni, Uwe Rau, and Thomas Kirchartz PRX Energy 2, 013004 (2023) – Published 9 March 2023 | Carrier diffusion length is not a reliable indicator of performance in some halide perovskite solar cells; instead, experiments and modeling show that properties of the carrier transport layers limit the performance. | | | | | | A.S. Menon, B.J. Johnston, S.G. Booth, L. Zhang, K. Kress, B.E. Murdock, G. Paez Fajardo, N.N. Anthonisamy, N. Tapia-Ruiz, S. Agrestini, M. Garcia-Fernandez, K. Zhou, P.K. Thakur, T.L. Lee, A.J. Nedoma, S.A. Cussen, and L.F.J. Piper PRX Energy 2, 013005 (2023) – Published 13 March 2023 | An experimental study reveals that the same oxidized O2− species appear in conventional layered cathodes as in oxygen-redox-active alkali-excess cathodes. | | | | | | Andreas Pusch, Udo Römer, Dimitrie Culcer, and Nicholas J. Ekins-Daukes PRX Energy 2, 013006 (2023) – Published 16 March 2023 | Energy conversion efficiency limits for the bulk photovoltaic effect, a mechanism for conversion of light into electricity in solids, are formulated and are more stringent than the Shockley Queisser limit. | | | | | | Zachary A.H. Goodwin, Michael McEldrew, Boris Kozinsky, and Martin Z. Bazant PRX Energy 2, 013007 (2023) – Published 23 March 2023 | A simple theory is developed to understand the underlying physical principles of competitive ionic aggregation and solvation for electrolytes in lithium-ion batteries. | | | | | | Jingda Zhang, Xie Zhang, Mark E. Turiansky, and Chris G. Van de Walle PRX Energy 2, 013008 (2023) – Published 24 March 2023 | A systematic first-principles study shows that the iodine vacancy does not lead to strong nonradiative losses in halide perovskites as commonly believed; thus, performance optimization strategies for perovskite solar cells should focus on other defects. | | | | | | Navid Zehtabiyan-Rezaie, Alexandros Iosifidis, and Mahdi Abkar PRX Energy 2, 013009 (2023) – Published 30 March 2023 | A machine-learning model is developed and used to predict the performance of individual wind turbines in wind farms; the strategy leads to an accurate, lightweight, and generalizable data-driven model for wind-farm power prediction. | | | | | | | |
