  • Advances in modelling and simulation of halide perovskites for solar cell

    • Authors: Chol-Jun Yu
      First page: 022001
      Abstract: Perovskite solar cells (PSCs) are attracting much attention as the most promising candidate for the next generation of solar cells. This is due to their low cost and high power conversion efficiency in spite of their relatively short period of development. Key components of PSCs are a variety of halide perovskites with ABX 3 stoichiometry, which are used as photoabsorbers. Their outstanding optoelectronic properties have brought breakthroughs in photovoltaic technology. To commercialize PSCs in the near future, however, these materials need to be further improved for better performance, represented by high efficiency and high stability. As in other materials development, atomistic modelling and simulation can play a significant role in finding new functional halide perovskites as well as revealing the underlying mechanisms of their material processes and properties. In this sense, computational work on the halide perovskites, mostly focusing on first-principles works, ...

  • The driving power of the electron

    • Authors: Mario Pagliaro; Francesco Meneguzzo
      First page: 011001
      Abstract: Almost two centuries after Carnot’s 1824 Réflexions sur la puissance motrice du feu (Paris : Bachelier Libraire), electricity stored in Li-ion batteries or made available by hydrogen fuel cells onboard, is becoming the energy form powering the mobility of vehicles, including: cars, buses, trucks, boats and ships. The conflicting dynamics of global wealth, energy and population requires the replacement of fossil fuels with truly renewable energy sources (sun, water and wind). This also implies the replacement of the ubiquitous internal combustion engine with the much more efficient electric motor powered by renewable electricity. Will the availability of lithium or cobalt intrinsically limit lithium battery manufacturing rapidly driving up battery production costs' Can we expect hydrogen fuel cell electric vehicles to become widely adopted as it is currently taking place with battery electric vehicles' Referring to recent research and industrial achievements, this st...

  • Understanding macroscale functionality of metal halide perovskites in
           terms of nanoscale heterogeneities

    • Authors: Tze-Bin Song; Ian D Sharp Carolin M Sutter-Fella
      First page: 011002
      Abstract: Hybrid metal halide perovskites have shown an unprecedented rise as semiconductor building blocks for solar energy conversion and light-emitting applications. Currently, the field moves empirically towards more and more complex chemical compositions, including mixed halide quadruple cation compounds that allow optical properties to be tuned and show promise for better stability. Despite tremendous progress in the field, there is a need for better understanding of mechanisms of efficiency loss and instabilities to facilitate rational optimization of composition. Starting from the device level and then diving into nanoscale properties, we highlight how structural and compositional heterogeneities affect macroscopic optoelectronic characteristics. Furthermore, we provide an overview of some of the advanced spectroscopy and imaging methods that are used to probe disorder and non-uniformities. A unique feature of hybrid halide perovskite compounds is the propensity for these heteroge...

  • 2D hybrid interlayer of electrochemically exfoliated graphene and Co(OH) 2
           nanosheet as a bi-functionalized polysulfide barrier for
           high-performance lithium–sulfur batteries

    • Authors: Haodong Shi; Yanfeng Dong, Feng Zhou, Jian Chen Zhong-Shuai Wu
      First page: 015002
      Abstract: Lithium sulfur (Li–S) batteries have attracted much attention because of high energy density, low cost and environmental friendliness. However, developing high-energy-density Li–S batteries is seriously hindered by their short cycling life, originating from the shuttle effect of soluble polysulfides. Herein we for the first time develop a versatile and facile strategy of assembling thin and lightweight bi-functionalized hybrid interlayer constructed by two-dimensional (2D) electrochemically exfoliated graphene and Co(OH) 2 nanosheets (EG/Co(OH) 2 ), positioned between the cathode and commercial polypropylene (PP) separator, for high-performance Li–S batteries with remarkably enhanced capacity, rate capability and long-term cyclability. The resulting 2D EG/Co(OH) 2 hybrid interlayer features layer-stacked structure, thin thickness of 5.5 μ m, high electrical conductivity of 900 S cm −1 , low mass loading of 0.20 mg cm −2 , and ...

  • Mechanistic study of the hydrodeoxygenation of lignin-derived oxygenates
           on a CoPt bimetallic catalyst: reaction of anisole on Co-modified

    • Authors: Daming Shi; John M Vohs
      First page: 015003
      Abstract: Temperature programmed desorption and high-resolution electron energy loss spectroscopy were used to characterize the adsorption and reaction of anisole (C 6 H 5 –OCH 3 ) on Pt(111) and Co-decorated Pt(111) surfaces. On both surfaces anisole was found to undergo O–CH 3 bond cleavage to form an oxocyclohexadienyl-structured intermediate (C 6 H 6 O) which bonds to the surface in a η 5 - π configuration. Interaction of the O atom in this intermediate with Co adatoms was found to facilitate selective cleavage of the C–O bond to produce adsorbed benzene or phenyl groups. In parallel with this pathway, unselective decomposition of adsorbed anisole was also found to occur. The results obtained in this study along with those previously reported for the reaction of anisole on Zn-decorated Pt(111) surfaces provide further insight into how the addition of a second more oxyphilic metal to Pt affects surface reacti...

  • Perovskite solar cells based on polyaniline derivatives as hole transport

    • Authors: Adriano S Marques; Rodrigo Szostak, Paulo E Marchezi Ana F Nogueira
      First page: 015004
      Abstract: Perovskite solar cells (PSC) have been extensively studied over the past few years in both academia and industry. Despite their appeal as a low cost and ease processing PV-technology, PSC still rely on materials that are expensive, turning the large-scale production more challenging. In this work, polyaniline (PAni) and its derivative poly(o-methoxyaniline) are employed as hole transport material (HTM) in PSC, replacing the most explored HTM, spiro-OMeTAD. These very well established conducting polymers are doped with 4-dodecylbenzenesulfonic acid (DBSA) to enhance their conductivity. The correlation between the performance of the solar cells using doped and undoped conducting polymers and different metallic contacts are also evaluated. The best power conversion efficiency was 10.05% using doped PAni-DBSA with Au as contact, which is similar to the performance exhibited by our standard device using Spiro-OMeTAD as HTM.

  • Hydrogen/manganese hybrid redox flow battery

    • Authors: Javier Rubio-Garcia; Anthony Kucernak, Dong Zhao, Danlei Li, Kieran Fahy, Vladimir Yufit, Nigel Brandon Miguel Gomez-Gonzalez
      First page: 015006
      Abstract: Electrochemical energy storage is a key enabling technology for further integration of renewables sources. Redox flow batteries (RFBs) are promising candidates for such applications as a result of their durability, efficiency and fast response. However, deployment of existing RFBs is hindered by the relatively high cost of the (typically vanadium-based) electrolyte. Manganese is an earth-abundant and inexpensive element that is widely used in disposable alkaline batteries. However it has hitherto been little explored for RFBs due to the instability of Mn(III) leading to precipitation of MnO 2 via a disproportionation reaction. Here we show that by combining the facile hydrogen negative electrode reaction with electrolytes that suppress Mn(III) disproportionation, it is possible to construct a hydrogen/manganese hybrid RFB with high round trip energy efficiency (82%), and high power and energy density (1410 mW cm −2 , 33 Wh l −1 ), at an estimated 70% ...

  • Observation of stimulated emission from Rhodamine 6G-polymer aggregate
           adsorbed at foam interfaces

    • Authors: Ketan Pancholi; Peter K J Robertson, Paul Okpozo, Neil S Beattie Dehong Huo
      First page: 015007
      Abstract: This paper reports for the first time the observation of stimulated emissions from the gas–liquid interface between two adjacent bubbles in highly ordered foams containing Rhodamine 6 G and surfactant. Stimulated emissions centred at 595 nm were observed when a monolayer of foam (∼liquid fraction 0.11), placed on a highly reflective surface, was pumped with a 532 nm continuous wave laser directed along ∼45° from the direction perpendicular to the substrate. Additionally, using confocal microscopy and micro-photoluminescence, it was found that the liquid fraction of the foam, the gap between two adjacent bubbles and the incidence angle of the laser are important parameters in guiding the light and promoting stimulated emissions at the interface. The adsorption of the polymer and dye increased the local concentration at the narrowest gaps between pairs of bubbles, which led to the formation of hemispherical micelles-dye agglomerates. The presence of the micelles aggregation caused...

  • Quick-start guide for first-principles modelling of semiconductor

    • Authors: Ji-Sang Park; Young-Kwang Jung, Keith T Butler Aron Walsh
      First page: 016001
      Abstract: Interfaces between dissimilar materials control the transport of energy in a range of technologies including solar cells (electron transport), batteries (ion transport), and thermoelectrics (heat transport). Advances in computer power and algorithms mean that first-principles models of interfacial processes in realistic systems are now possible using accurate approaches such as density functional theory. In this ‘quick-start guide’, we discuss the best practice in how to construct atomic models between two materials and analysis techniques appropriate to probe changes in local bonding and electronic band offsets. A number of examples are given related to perovskite solar cells.
