text: The defect-electronic properties of {112} microfaceted surfaces of epitaxially
grown CuInSe2 thin films are investigated by scanning tunneling spectroscopy and
photoelectron spectroscopy techniques after various surface treatments. The intrinsic
CuInSe2 surface is found to be largely passivated in terms of electronic defect
levels in the band-gap region. However, surface oxidation leads to an overall
high density of defect levels in conjunction with a considerable net surface dipole,
which persists even after oxide removal. Yet, a subsequent annealing under vacuum
restores the initial condition. Such oxidation/reduction cycles are reversible
for many times providing robust control of the surface and interface properties
in these materials. Based on ab initio simulations, a mechanism where oxygen dissociatively
adsorbs and subsequently diffuses to a subsurface site is proposed as the initial
step of the observed dipole formation. Our results emphasize the relevance of
oxidation-induced dipole effects at the thin film surface and provide a comprehensive
understanding toward passivation strategies of these surfaces.

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: Rechargeable aqueous Zn-ion energy storage devices are promising candidates
for next-generation energy storage technologies. However, the lack of highly reversible
Zn2+-storage anode materials with low potential windows remains a primary concern.
Here, we report a two-dimensional polyarylimide covalent organic framework (PI-COF)
anode with high-kinetics Zn2+-storage capability. The well-organized pore channels
of PI-COF allow the high accessibility of the build-in redox-active carbonyl groups
and efficient ion diffusion with a low energy barrier. The constructed PI-COF
anode exhibits a specific capacity (332 C g–1 or 92 mAh g–1 at 0.7 A g–1), a high
rate capability (79.8% at 7 A g–1), and a long cycle life (85% over 4000 cycles).
In situ Raman investigation and first-principle calculations clarify the two-step
Zn2+-storage mechanism, in which imide carbonyl groups reversibly form negatively
charged enolates. Dendrite-free full Zn-ion devices are fabricated by coupling
PI-COF anodes with MnO2 cathodes, delivering excellent energy densities (23.9
∼ 66.5 Wh kg–1) and supercapacitor-level power densities (133 ∼ 4782 W kg–1).
This study demonstrates the feasibility of covalent organic framework as Zn2+-storage
anodes and shows a promising prospect for constructing reliable aqueous energy
storage devices.

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.

text: 'AbstractElectroencephalographic (EEG) research
indicates changes in adults’ low frequency bands of frontoparietal brain areas
executing different balance tasks with increasing postural demands. However, this
issue is unsolved for adolescents when performing the same balance task with increasing
difficulty. Therefore, we examined the effects of a progressively increasing balance
task difficulty on balance performance and brain activity in adolescents. Thirteen
healthy adolescents aged 16–17 year performed tests in bipedal upright stance
on a balance board with six progressively increasing levels of task difficulty.
Postural sway and cortical activity were recorded simultaneously using a pressure
sensitive measuring system and EEG. The power spectrum was analyzed for theta
(4–7 Hz) and alpha-2 (10–12 Hz) frequency bands in pre-defined frontal, central,
and parietal clusters of electrocortical sources. Repeated measures analysis of
variance (rmANOVA) showed a significant main effect of task difficulty for postural
sway (p < 0.001; d = 6.36).
Concomitantly, the power spectrum changed in frontal, bilateral central, and bilateral
parietal clusters. RmANOVAs revealed significant main effects of task difficulty
for theta band power in the frontal (p < 0.001,
d = 1.80) and both central clusters (left: p < 0.001,
d = 1.49; right: p < 0.001,
d = 1.42) as well as for alpha-2 band power in both
parietal clusters (left: p < 0.001, d = 1.39;
right: p < 0.001, d = 1.05)
and in the central right cluster (p = 0.005, d = 0.92).
Increases in theta band power (frontal, central) and decreases in alpha-2 power
(central, parietal) with increasing balance task difficulty may reflect increased
attentional processes and/or error monitoring as well as increased sensory information
processing due to increasing postural demands. In general, our findings are mostly
in agreement with studies conducted in adults. Similar to adult studies, our data
with adolescents indicated the involvement of frontoparietal brain areas in the
regulation of postural control. In addition, we detected that activity of selected
brain areas (e.g., bilateral central) changed with increasing postural demands.'
