Stabilizing halide perovskite surfaces for solar cell operation with wide-bandgap lead oxysalts
Science, 2019 Stability through oxysalts The stability of organic-inorganic perovskite solar cells is limited by degradation from oxygen and water. Yang et al. show that in situ reaction of perovskites with sulfate or phosphate ions can create thin, strongly bonded ...

Leading Singularities and Classical Gravitational Scattering [PDF]
arXiv, 2017 In this work we propose to use leading singularities to obtain the classical pieces of amplitudes of two massive particles whose only interaction is gravitational. Leading singularities are generalizations of unitarity cuts. At one-loop we find that leading singularities obtained by multiple discontinuities in the t-channel contain all the classical ...

Evaluation of the Hispanic Paradox: Conceptualized Through the Lens of Generational Decision-Making Styles of First-, Second-, and Third-Plus-Generation Hispanic Leaders [PDF]
, 2023 The primary objective of this dissertation was first to ascertain whether there is a statistically significant effect of generation on decision-making styles and secondarily to ascertain whether there would be a statistically significant interaction ...

The Analytical Solution of the Lag-Lead Compensator [PDF]
arXiv, 2009 In this paper, we first give the analytical solution of the general lag-lead compensator design problem. Then, we show why a series of more than 5 phase-lead/phase-lag compensator cannot be solved analytically using the Galois Theory.

Ruddlesden-Popper Hybrid Lead Iodide Perovskite 2D Homologous Semiconductors
, 2016 The hybrid two-dimensional (2D) halide perovskites have recently drawn significant interest because they can serve as excellent photoabsorbers in perovskite solar cells.

Prospects for low-toxicity lead-free perovskite solar cells
Nature Communications, 2019 Since the 2012 breakthroughs1–3, it is now very much accepted that halide perovskite solar cells may have a strong practical impact in next-generation solar cells. The most efficient solar cells are using Pb-based halide perovskites.

New extensions to the sumsets with polynomial restrictions [PDF]
arXiv, 2012 By taking the leading and the second leading coefficients of the Morris identity, we get new polynomial coefficients. These coefficients lead to new results in the sumsets with polynomial restrictions by the polynomial method of N. Alon.

Hybrid Dion-Jacobson 2D Lead Iodide Perovskites.
Journal of the American Chemical Society, 2018 The three-dimensional hybrid organic-inorganic perovskites have shown huge potential for use in solar cells and other optoelectronic devices. Although these materials are under intense investigation, derivative materials with lower dimensionality are ...
