Plasmonic Thin Film Solar Cellscells
ProvisionalChapter chapter 7 Plasmonic Thin Film Solar CellsCells Qiuping Huang, Xiang Hu, Zhengping Fu and Qiuping Huang , Xiang Hu , Zhengping Fu and Yalin Lu Yalin Lu Additional information is available at the end of the chapter Additional information is available at the end of the chapter http://dx.doi.org/10.5772/65388 Abstract Thin film solar cell technology represents an alternative way to effectively solve the world’s increasing energy shortage problem. Light trapping is of critical importance. Surface plasmons (SPs), including both localized surface plasmons (LSPs) excited in the metallic nanoparticles and surface plasmon polaritons (SPPs) propagating at the metal/ semiconductor interfaces, have been so far extensively investigated with great interests in designing thin film solar cells. In this chapter, plasmonic structures to improve the performance of thin film solar cell are reviewed according to their positions of the nanostructures, which can be divided into at least three ways: directly on top of thin film solar cell, embedded at the bottom or middle of the optical absorber layer, and hybrid of metallic nanostructures with nanowire of optical absorber layer. Keywords: thin film solar cells, light trapping, localized surface plasmons (LSPs), sur‐ face plasmon polaritons (SPPs), light absorption enhancement 1. Introduction Photovoltaic technology, the conversion of solar energy to electricity, can help to solve the energy crisis and reduce the environmental problems induced by the fossil fuels. Worldwide photovoltaic production capacity at the end of 2015 is estimated to be about 60 GW [1] and is expected to keep rising. Yet, there is great demand for increasing the photovoltaic device efficiency and cutting down the cost of materials, manufacturing, and installation. -
BEC Dark Matter Can Explain Collisions of Galaxy Clusters
BEC dark matter can explain collisions of galaxy clusters Jae-Weon Lee∗ School of Computational Sciences, Korea Institute for Advanced Study, 207-43 Cheongnyangni 2-dong, Dongdaemun-gu, Seoul 130-012, Korea Sooil Lim Department of Physics and Astronomy, Seoul National University, Seoul, 151-747, Korea Dale Choi∗ Korea Institute of Science and Technology Information, Kwahanro 335, Yuseong-Gu, Daejeon, 305-806, South Korea (Dated: October 31, 2018) We suggest that the dark matter model based on Bose Einstein condensate or scalar field can resolve the apparently contradictory behaviors of dark matter in the Abell 520 and the Bullet cluster. During a collision of two galaxies in the cluster, if initial kinetic energy of the galaxies is large enough, two dark matter halos pass each other in a soliton-like way as observed in the Bullet cluster. If not, the halos merge due to the tiny repulsive interaction among dark matter particles as observed in the Abell 520. This idea can also explain the origin of the dark galaxy and the galaxy without dark matter.

2.2.10 Plasmonic Photovoltaics
Plasmonic Photovoltaics Investigators Harry A. Atwater, Howard Hughes Professor and Professor of Applied Physics and Materials Science, California Institute of Technology Krista Langeland, Ph.D. student, Materials Science, California Institute of Technology Imogen Pryce, Ph.D. student, Chemical Engineering, California Institute of Technology Vivian Ferry, Ph.D student, Chemistry, California Institute of Technology Deirdre O’Carroll, postdoc, Applied Physics, California Institute of Technology Abstract We summarize results for the period May 2008-April 2009 for the plasmonic photovoltaics three year GCEP project. We have made progress in two key areas: 1) we have analyzed enhanced optical absorption in plasmonic solar cells theoretically and via full field electromagnetic simulation and coupled full field electromagnetic simulations to semiconductor device physics simulations and design tools 2) we have designed and fabricated a prototype single quantum well plasmonic solar cell with InGaN/GaN heterostructures. These prototype InGaN cells exhibit enhanced absorption and enhanced photocurrent due to plasmonic nanoparticle scattering, in a 2.5 nm thick quantum well. Introduction The plasmonic photovoltaics project is a joint Caltech-Stanford-Utrecht/FOM research program which exploits recent advances in plasmonics to realize high efficiency solar cells based on enhanced absorption and carrier collection in ultrathin film, quantum wire and quantum dot solar cells with multispectral absorber layers. The program has three key focal points: 1) design and realization of plasmonic structures to enhance solar light absorption in ultrathin film and low-dimensional inorganic semiconductor absorber layers; this is the largest area of effort for the proposed effort; 2) synthesis of earth-abundant semiconductors in ultrathin films and low- dimensional (quantum wire and quantum dot) multijunction and multispectral absorber layers; 3) investigation of carrier transport and collection in ultrathin plasmonic solar cells. -
Axion-Higgs 3-Dimensional Rigid Transformable Strings and the Compound 650 Gev Z-Z Decay Into Quarks/Leptoquarks
The Magic of Life- and Matter Creating Self Propelled Electric Dark Matter Black Holes Guided by a Holographic Entangled Symmetric Multiverse System. Leo Vuyk, Architect, Rotterdam, the Netherlands. Abstract, In Quantum Function Follows Form Theory, ( Q-FFF Theory) the Big Bang was the evaporation and splitting of a former Big Crunch black hole nucleus of compressed massless Axion Higgs particles. The Big Bang Nucleus of compressed massless Axion /Higgs particles is assumed to be split into respectively chunky nuclei of dark matter black holes called plasma /matter creating Quasars, or evaporated as singular massless Axion Higgs vacuum particles oscillating along a tetrahedral shaped chiral vacuum lattice. The vacuum Lattice is supposed to represent a dynamic reference frame with variable local length and so called Dark Energy or Zero Point Energy acting as the motor for all Fermion spin and eigen energy and as the transfer medium for all photon information, leading to local lightspeed and local time. The energetic oscillating vacuum lattice is assumed to act as a Gravity Quantum Dipole Repeller (or large scale Casimir effect) Gravitons are not supposed to attract- but repel Fermions with less impulse than vacuum particle pressure does. So, gravity is assumed to be a dual pressure process on fermions. As a consequence, Feynman diagrams become more complex than before.. Recent measurements by Yehuda Hoffman et al. did show the repelling effect of “empty space” in opposition of the “attracting gravity effect” of super clusters which he called “Dipole Repeller” effect. The universe is supposed to be Holographic by the instant long distance entanglement particle guidance between Charge Parity Symmetric Universes; the Multiverse. -

Methods for Tuning Plasmonic and Photonic Optical Resonances in High Surface Area Porous Electrodes Lauren M
www.nature.com/scientificreports OPEN Methods for tuning plasmonic and photonic optical resonances in high surface area porous electrodes Lauren M. Otto1,2,3, E. Ashley Gaulding3,4, Christopher T. Chen2, Tevye R. Kuykendall2, Aeron T. Hammack2, Francesca M. Toma3,4, D. Frank Ogletree2, Shaul Aloni2, Bethanie J. H. Stadler1 & Adam M. Schwartzberg2* Surface plasmons have found a wide range of applications in plasmonic and nanophotonic devices. The combination of plasmonics with three-dimensional photonic crystals has enormous potential for the efcient localization of light in high surface area photoelectrodes. However, the metals traditionally used for plasmonics are difcult to form into three-dimensional periodic structures and have limited optical penetration depth at operational frequencies, which limits their use in nanofabricated photonic crystal devices. The recent decade has seen an expansion of the plasmonic material portfolio into conducting ceramics, driven by their potential for improved stability, and their conformal growth via atomic layer deposition has been established. In this work, we have created three-dimensional photonic crystals with an ultrathin plasmonic titanium nitride coating that preserves photonic activity. Plasmonic titanium nitride enhances optical felds within the photonic electrode while maintaining sufcient light penetration. Additionally, we show that post-growth annealing can tune the plasmonic resonance of titanium nitride to overlap with the photonic resonance, potentially enabling coupled-phenomena applications for these three-dimensional nanophotonic systems. Through characterization of the tuning knobs of bead size, deposition temperature and cycle count, and annealing conditions, we can create an electrically- and plasmonically-active photonic crystal as-desired for a particular application of choice. -
