  text: "<jats:title>Abstract</jats:title>\r\n               <jats:p>Dual-ion batteries
    are considered to be an emerging viable energy storage technology owing to their
    safety, high power capability, low cost, and scalability. Intercalation of anions
    into a graphite positive electrode provides high operating voltage and improved
    energy density to such dual-ion batteries. In this work, we have performed a combinatorial
    study of graphite intercalation compounds considering four anions, namely hexafluorophosphate

    bis(fluorosulfonyl)imide (FSI<jats:sup>−</jats:sup>), and bis(trifluoromethanesulfonyl)imide
    (TFSI<jats:sup>−</jats:sup>), via first-principles calculations. The structural
    properties and energetics of the intercalation compounds are compared based on
    different sizes, geometries, and the physical and chemical properties of the intercalated
    anions. The staging mechanism of anion intercalation into graphite and the specific
    capacities, and voltage profiles of the intercalated compounds are investigated.
    A comparison regarding battery electrochemistry is also done with available experimental
    observations. Our calculated intercalation energies and voltage profiles show
    that the initial anion intercalation into graphite is less favorable than subsequent
    ones for all the anions considered in this study. Although the effect of the size
    of anions in a graphite cathode on various properties of the intercalated compounds
    is not as significant as the size of cations in a graphite anode, some distinction
    between the studied anions can still be made. Among the studied anions, the intercalation

    anions cause relatively small structural deformations of the graphite and have
    the highest oxidative ability, highest onset voltage, and highest diffusion barrier
    along the graphene sheets. The overall small diffusion barriers of the anions
    within graphite explain the high rate capability of dual-ion batteries.</jats:p>"

  text: Photovoltaics is one of the most promising and fastest-growing renewable energy
    technologies. Although the price-performance ratio of solar cells has improved
    significantly over recent years{,} further systematic investigations are needed
    to achieve higher performance and lower cost for future solar cells. In conjunction
    with experiments{,} computer simulations are powerful tools to investigate the
    thermodynamics and kinetics of solar cells. Over the last few years{,} we have
    developed and employed advanced computational techniques to gain a better understanding
    of solar cells based on copper indium gallium selenide (Cu(In{,}Ga)Se2). Furthermore{,}
    we have utilized state-of-the-art data-driven science and machine learning for
    the development of photovoltaic materials. In this Perspective{,} we review our
    results along with a survey of the field.

  text: Lead halide perovskite semiconductors providing record efficiencies of solar
    cells have usually mixed compositions doped in A- and X-sites to enhance the phase
    stability. The cubic form of formamidinium (FA) lead iodide reveals excellent
    opto-electronic properties but transforms at room temperature (RT) into a hexagonal
    structure which does not effectively absorb visible light. This metastable form
    and the mechanism of its stabilization by Cs+ and Br− incorporation are poorly
    characterized and insufficiently understood. We report here the vibrational properties
    of cubic FAPbI3 investigated by DFT calculations on phonon frequencies and intensities,
    and micro-Raman spectroscopy. The effects of Cs+ and Br− partial substitution
    are discussed. We support our results with the study of FAPbBr3 which expands
    the identification of vibrational modes to the previously unpublished low frequency
    region (<500 cm−1). Our results show that the incorporation of Cs+ and Br− leads
    to the coupling of the displacement of the A-site components and weakens the bonds
    between FA+ and the PbX6 octahedra. We suggest that the enhancement of α-FAPbI3
    stability can be a product of the release of tensile stresses in the Pb–X bond,
    which is reflected in a red-shift of the low frequency region of the Raman spectrum
    (<200 cm−1).

  text: The record conversion efficiency of thin-film solar cells based on Cu(In,Ga)Se2
    (CIGS) absorbers has exceeded 23%. Such a high performance is currently only attainable
    by the incorporation of heavy alkali metals like Cs into the absorber through
    an alkali fluoride post-deposition treatment (PDT). As the effect of the incorporated
    heavy alkali metals is under discussion, we investigated the local composition
    and microstructure of high efficiency CIGS solar cells via various high-resolution
    techniques in a combinatory approach. An accumulation of Cs is clearly detected
    at the p-n junction along with variations in the local CIGS composition, showing
    the formation of a beneficial secondary phase with a laterally inhomogeneous distribution.
    Additionally, Cs accumulations were detected at grain boundaries with a random
    misorientation of the adjacent grains where a reduced Cu concentration and increased
    In and Se concentrations are detected. No accumulation was found at Σ3 twin boundaries
    as well as the grain interior. These experimental findings are in excellent agreement
    with complementary ab-initio calculations, demonstrating that the grain boundaries
    are passivated by the presence of Cs. Further, it is unlikely that Cs with its
    large ionic radius is incorporated into the CIGS grains where it would cause detrimental
    defects.
