description: The fifth generation wireless networks must provide fast and reliable connectivity while coping with the ongoing traffic growth. It is of paramount importance that the required resources, such as energy and bandwidth, do not scale with traffic. While the aggregate network traffic is growing at an unprecedented rate, users tend to request the same popular contents at different time instants. Therefore, caching the most popular contents at the network edge is a promising solution to reduce the traffic and the energy consumption over the backhaul links. In this paper, two scenarios are considered, where caching is performed either at a small base station, or directly at the user terminals, which communicate using \ac{D2D} communications. In both scenarios, joint design of the transmission and caching policies is studied when the user demands are known in advance. This joint design offers two different caching gains, namely, the \textit{pre-downloading} and \textit{local caching gains}. It is shown that the finite cache capacity limits the attainable gains, and creates an inherent tradeoff between the two types of gains. In this context, a continuous time optimization problem is formulated to determine the optimal transmission and caching policies that minimize a generic cost function, such as energy, bandwidth, or throughput. The jointly optimal solution is obtained by demonstrating that caching files at a constant rate is optimal, which allows to reformulate the problem as a finite-dimensional convex program. The numerical results show that the proposed joint transmission and caching policy dramatically reduces the total cost, which is particularised to the total energy consumption at the \ac{MBS}, as well as to the total economical cost for the service provider, when users demand economical incentives for delivering content to other users over the D2D links.

description: The effect of active layer thickness on the performance of poly [N-9’-hepta-decanyl-2,7-carbazole-alt-
5,5-(40,70-di-2-thienyl-20,10,30-benzothiadiazole)] (PCDTBT) and [6,6]-phenyl C71-butyric acid methyl ester
(PC71BM) based solar cells was investigated. The active layer thickness of devices were varied following the
approach of layer by layer growth. The cells were fabricated on an indium tin oxide (ITO)-coated glass substrate
bearing the structure: ITO /poly(3,4- ethylene-dioxythiophene) (PEDOT:PSS)/PCDTBT:PC71BM/Al. It has been
observed that the open circuit voltage (Voc) gradually increases from 0.52 V for a single layer device to 0.80 V for a
multilayer (5 layers) device. However, the short circuit current density (Jsc) is found to decrease from 17.33 mA/cm2
to 7.51 mA/cm2. Due to this reduction in current density the efficiency of multilayer devices is reduced down to
1.53% from 3.55% under 1 Sun illumination. The intensity variation experiments suggested that Jsc is monotonously
increasing with the increase in input power and maintains a constant Voc value. It has been inferred that that Jsc is not
limited due to external fields but a pronounced recombination process is hindering a significant fraction of the
separated charge to reach to respective electrodes. The device performance was significantly improved by thermal
annealing of multilayered solar cells and an efficiency of 2.5 % was attained back.

description: We performed Raman studies and a dielectric characterization of the pseudo-kagome Cu3Bi(SeO3)2O2X (X = Cl, Br). These compounds share competing nearest-neighbour ferromagnetic exchange and frustrating next-nearest-neighbour antiferromagnetic exchange as well as highly noncollinear magnetic ground state. However, at low temperature they differ with respect to the existence of inversion symmetry. For both compounds there exists a pronounced interplay of polar phonon modes with quantum magnetic fluctuations. A novel Raman mode appears for temperatures below the Neel temperature with a Fano lineshape and an enormous intensity that exceeds most of the phonon lines. We discuss a possible contribution of longitudinal magnons to this signal. In contrast, one magnon scattering based on linear transvers magnons is excluded based on a symmetry analysis of spin wave representations and Raman tensor calculations. There exists evidence that in these pseudo-kagome compounds magnetic quantum fluctuations carry an electric dipole moment. Our data as well as a comparison with previous far-infrared spectra allow us to conclude that Cu3Bi(SeO3)2O2Cl changes its symmetry most likely from Pmmn to P21mn with a second order structural phase transition at T*=120 K and becomes multiferroic. Cu3Bi(SeO3)2O2Br represents an interesting counter part as it does not show this instability and stays inversion symmetric down to lowest temperatures, investigated.

description: The study of the properties of galaxies in the first billion years after the Big Bang is one of the major topic of current astrophysics. Optical/near-infrared spectroscopy of the afterglows of long Gamma-ray bursts (GRBs) provide a powerful diagnostic tool to probe the interstellar medium (ISM) of their host galaxies and foreground absorbers, even up to the highest redshifts. We analyze the VLT/X-shooter afterglow spectrum of GRB 210905A, triggered by the Swift Neil Gehrels Observatory, and detect neutral-hydrogen, low-ionization, high-ionization, and fine-structure absorption lines from a complex system at z=6.3118, that we associate with the GRB host galaxy. We study the ISM properties of the host system, revealing the metallicity, kinematics and chemical abundance pattern. The total metallicity of the z~6.3 system is [M/H]=-1.72+/-0.13, after correcting for dust-depletion and taking into account alpha-element enhancement. In addition, we determine the overall amount of dust and dust-to-metal mass ratio (DTM) ([Zn/Fe]_fit=0.33+/-0.09, DTM=0.18+/-0.03). We find indications of nucleosynthesis due to massive stars and evidence of peculiar over-abundance of aluminium. From the analysis of fine-structure lines, we determine distances of several kpc for the low-ionization gas clouds closest to the GRB. Those farther distances are possibly due to the high number of ionizing photons. Using the HST/F140W image of the GRB field, we show the GRB host galaxy as well as multiple objects within 2" from the GRB. We discuss the galaxy structure and kinematics that could explain our observations, also taking into account a tentative detection of Lyman-alpha emission. Deep spectroscopic observations with VLT/MUSE and JWST will offer the unique possibility of combining our results with the ionized-gas properties, with the goal of better understanding how galaxies in the reionization era form and evolve.

A stochastic Galerkin method for general system of quasilinear hyperbolic conservation laws with uncertainty

Year: 2016
Subjects: subject: Numerical Analysis (math.NA)

description: This paper is concerned with generalized polynomial chaos (gPC) approximation for a general system of quasilinear hyperbolic conservation laws with uncertainty. The one-dimensional (1D) hyperbolic system is first symmetrized with the aid of left eigenvector matrix of the Jacobian matrix. Stochastic Galerkin method is then applied to derive the equations for the gPC expansion coefficients. The resulting deterministic gPC Galerkin system is proved to be symmetrically hyperbolic. This important property then allows one to use a variety of numerical schemes for spatial and temporal discretization. Here a higher-order and path-conservative finite volume WENO scheme is adopted in space, along with a third-order total variation diminishing Runge-Kutta method in time. The method is further extended to two-dimensional (2D) quasilinear hyperbolic system with uncertainty, where the symmetric hyperbolicity of the one-dimensional system is carried over via the operator splitting technique. Several 1D and 2D numerical experiments are conducted to demonstrate the accuracy and effectiveness of the proposed gPC stochastic Galerkin method.

description: Alfvén waves (AWs) are inevitable in space and astrophysical plasma. Their crucial role in various physical processes, occurring in plasma, has triggered intense research in solar-terrestrial physics. Simulation studies have proposed the generation of AWs along the surface of a cylindrical flux rope, referred to as Surface AWs (SAWs); however the observational verification of this distinct wave has been elusive to date. We report the first \textit{in-situ} observation of SAWs in an interplanetary coronal mass ejection flux rope. We apply the Walén test to identify them. The Elsasser variables are used to estimate the characterization of these SAWs. They may be excited by the movement of the flux rope's foot points or by instabilities along the plasma magnetic cloud's boundaries. Here, the change in plasma density or field strength in the surface-aligned magnetic field may trigger SAWs.

Unlike the other methods of deposition like spin coating, inkjet printing etc. requiring post-deposition annealing, spray process under an electric field was done to achieve improvements in the film properties. The gas pressure and the electric field were used together for the atomization,with the electric field created by applying DC voltage of 500 V to the nozzle and circular electrode placed 4 mm below the nozzle. The crystallinity and absorption of PCPDTBT layer got enhanced in comparison to spray deposited PCPDTBT layer without the electric field. Different kinds of microstructures were formed in both the spray deposited PCPDTBT layer. These microstructures got uniform and finer on applying the DC voltage during spray deposition. Incorporation of electric field annealing as a part of the spray deposition to improve the deposited layer characteristics, along with inherent advantages of low cost, large area coverage, less material consumption and deposition on rigid as well as flexible substrates, will help in making better organic solar cells using this process.

description: Nova explosions occur on the white dwarf component of a Cataclysmic Variable binary stellar system that is accreting matter lost by its companion. When sufficient material has been accreted by the white dwarf, a thermonuclear runaway occurs and ejects material in what is observed as a Classical Nova explosion. We describe both the recent advances in our understanding of the progress of the outburst and outline some of the puzzles that are still outstanding. We report on the effects of improving both the nuclear reaction rate library and including a modern nuclear reaction network in our one-dimensional, fully implicit, hydrodynamic computer code. In addition, there has been progress in observational studies of Supernovae Ia with implications about the progenitors and we discuss that in this review.

description: Bulk heterojunction (BHJ) solar cells are becoming an established alternative to other low-cost
solutions in new generation photovoltaics. As a direct successor to bilayer junction solar cells, the BHJ offers greater
efficiency at dissociating excitons by increasing the junction area. Moreover, the morphology of the BHJ is crucial to
its performance, where a bicontinuous, interconnected, phase separated morphology of donor and acceptor phases,
forming a finger like structure is believed to be optimal. In this work, we present a model and a method to analyze
properties of BHJ layer in fully operational solar cells in a sense of Dissociation and Collection Efficiency (DCE).
This parameter describes the probability at which photogenerated excitons are dissociated into free charges
collectable at the both sides of BHJ, while linking its parameters to the morphology of the BHJ itself. This allows
non-destructive analysis of the morphology of the BHJ in a working, sealed photovoltaic device based on BHJ.

description: In the field of inverted organic solar cells technology two ways of thermal treatment are commonly
used, pre- and post-annealing. This work is focused on investigation the J-V curve shapes and performances under
various light intensities of the pre-, post- and also non-annealing solar cells based on P3HT:PCBM. Pre-annealed
samples were thermal treated at 150oC for 90 min before thermal evaporation of MoO3 and Ag. Post-annealed solar
cells were annealed at 150oC for 15 min after the vacuum processes. The current-voltage characteristics
of ITO/ZnO/P3HT:PCBM/ MoO3/Ag solar cells were measured under various illumination intensity from 0.2 to 100
mW/cm2. Device efficiencies under 100 mW/cm2, 2.15%, 1.51% and 0.38% were obtained for the pre-, post- and
non-annealed samples, respectively. Efficiencies of post- and non-annealed solar cells is increasing with decreasing
the incident light intensity, even up to 3%, as opposed to the pre-annealed cells of which the efficiency is decreasing
to 1.25%. Stability of fabricated solar cells was monitored for few months. This study will allow to define conditions
of thermal treatment to produce stable in time organic solar cell with high efficiency under a wide range of light
intensity (0.2 to 100 mW/cm2).

description: Frenkel polaritons, hybrid light-matter quasiparticles, offer promises for the designing of new opto-electronic devices. However, their technological implementations are hindered by sensitivity to imperfections. Topology has raised as a way to circumvent defects and fabrication limitations. Here, we propose a lattice of cavities to realize the one-dimensional Su-Schrieffer-Heeger model (SSH) for topological Frenkel polaritons. By engineering the configuration of the cavities we demonstrate that the SSH topological and trivial phases can be accessed, which we unravel by complementary classical and quantum theories. We demonstrate the polariton edge state robustness under defects and the broadening of the photon and exciton lines. Our findings propose a realistic yet simple experimental setup to realize topological room temperature polaritons.

description: We present a simple yet accurate numerical approach to compute the free energy of binding of multivalent objects on a receptor-coated surface. The method correctly accounts for the fact that one ligand can bind to at most one receptor. The numerical approach is based on a saddle-point approximation to the computation of a complex residue. We compare our theory with the powerful Valence-Limited Interaction Theory (VLIT) (J. Chem. Phys. 137, 094108(2012), J. Chem. Phys. 138, 021102(2013)) and find excellent agreement in the regime where that theory is expected to work. However, the present approach even works for low receptor/ligand densities, where VLIT breaks down.

methylimi-dazolium bromide on the surface of graphene oxide (GO), and followed by anion-exchange with
bis(trifluoromethanesulfonyl)imide ions (TFSI-). Environmental friendly ionic liquid-based composite electrolyte for
dye sensitized solar cells (DSSCs) without volatile organic solvents is prepared via dispersion of IL-GO in room
temperature ionic liquids, 1-propyl-3-methylimidazolium iodide (PMII). Incorporation of proper amount of IL-GO
significantly increased the conductivity of the electrolytes, the open circuit voltage, the short circuit current density
and the conversion efficiency of DSSCs. The device which containing 4 wt% of IL-GO composite electrolyte shows
an overall power conversion efficiency of 7.04% under simulated AM 1.5 solar spectrum irradiation at 100 mW cm−2.
These results indicate that the DSSCs based on IL-GO/IL composite electrolytes could overcome the drawbacks of
volatile liquid electrolytes, and offer a feasible method to fabricate DSSCs in future practical applications.

title: "Ich will ja niemanden mit meiner Kompetenz überraschen" - die Intersektionalität von Mikroaggressionen und ihre Verbindung zum Impostor Phänomen
Creators: name: Wüstehube, Hannah
Year: 2023

description: Die Bildungssituation für Frauen und Menschen mit Migrationsgeschichte in Österreich ist weiterhin prekär, eine Bildungsbenachteiligung zeigt sich teilweise bereits im Schulkontext. Abseits von strukturellen Barrieren hat das Impostor Phänomen als psychologische Barriere erheblichen Einfluss auf die Bildungskarriere von marginalisierten Personen. Das Impostor Phänomen beschreibt das Gefühl der intellektuellen Falschheit und Inkompetenz, während betroffene Personen objektiv hohe Leistungen erbringen. Der heutige Forschungsstand weist auf eine besondere Betroffenheit von mehrfach marginalisierten Personen hin. Eine mögliche Erklärung dafür sind erlebte Mikroaggressionen, also verbale, non-verbale und/oder behaviourale negative Botschaften, die einem Individuum aufgrund seiner Gruppenzugehörigkeit vermittelt werden. Mehrfach marginalisierte Personen berichten über ein hochfrequentes Erleben solcher Mikroaggressionen. Diese Diskriminierungserfahrungen führen zu internalisierter Unterdrückung, welche sich in Form von Impostorgefühlen äußern können. Die vorliegende Studie beschäftigt sich mit dem Erleben von Frauen mit Migrationsgeschichte in Österreich und betrachtet die Verbindung von Mikroaggressionen, internalisierter Unterdrückung und dem Impostor Phänomen. Um ein möglichst ganzheitliches Arbeiten zu ermöglichen, wurde mit einem zweistufigen Verfahren gearbeitet. Zuerst wurde ein quantitativer Onlinefragebogen verbreitet, um damit ein Screening mit der deutschen Version der Clance Impostor Phänomen Skala (CIPS) zu ermöglichen. Im Anschluss daran wurde mit 6 Frauen, welche Werte im deutschen CIPS >60, studieren oder studiert haben und Migrationsgeschichte haben, ein qualitatives offenes Leitfadeninterview geführt. Die erhobenen Daten bestätigten den Zusammenhang von Mikroaggressionen, internalisierter Unterdrückung und dem Impostor Phänomen umfangreich. Implikationen für den Bildungskontext werden diskutiert.

description: Upon ageing of ionic liquid based dye-sensitized solar cells (DSSCs) formation of iodine containing
crystals may happen. Herein we show how these crystals can reversibly change in size and how this affects the cell
performance if the cells are (i) stored in the dark at room temperature, (ii) exposed to heat treatment at 80 °C and
exposed to (iii) reverse or (iv) forward bias current treatment. Crystal change in size was tracked using
electroluminescence, while we used current-voltage characterization to determine cell performance. Results reveal
the growth of the crystals when the cells were stored in the dark at room temperature while a heat treatment dissolves
the crystals. The growth of the crystals is associated with a loss of the I3– ions in the electrolyte which decrease the
short-circuit current and increase the open-circuit voltage.

description: We study the dijet azimuthal de-correlation in relativistic heavy ion collisions as an important probe of the transverse momentum broadening effects of a high energy jet traversing the quark-gluon plasma. We take into account both the soft gluon radiation in vacuum associated with the Sudakov logarithms and the jet P_T-broadening effects in the QCD medium. We find that the Sudakov effects are dominant at the LHC, while the medium effects can play an important role at RHIC energies. This explains why the LHC experiments have not yet observed sizable P_T-broadening effects in the measurement of dijet azimuthal correlations in heavy ion collisions. Future investigations at RHIC will provide a unique opportunity to study the P_T-broadening effects and help to pin down the underlying mechanism for jet energy loss in a hot and dense medium.

description: In this paper a novel dye-sensitized solar cell (DSSC) architecture based on vertically aligned ZnO
nanowire grown on multiwall carbon nanotubes is demonstrated. The novel selective hierarchical growth approach
represents a cost-effective, all solution processed chemical bath deposition method that yields complex hierarchical
ZnO nanowire photoanodes by utilizing a simple engineering of seed particles. The effects of precursor
concentration, growth temperature and time duration on the structure of zinc oxide nanowires were investigated. An
encouraging overall conversion efficiency of 1.1% and a rather high open-circuit voltage of 0.35V have been
achieved. The efficient charge separation at the ZnO nanowire –multiwall carbon nanotube junction and the large
outer ZnO surface of this core shell architecture provide new methods to tune the materials and interfaces in solar
cells. The nanostructures produced were characterized by X-ray diffraction, scanning electron microscopy, X-ray
photoelectron spectroscopy, and Raman spectroscopy. The field emission properties and stability of the fabricated
nanostructures were studied and show great potential for field emission applications.

description: We investigate the magnetic activity of the G dwarf primary star in the multiple system V815 Herculis. Recently, TESS Sector 26 data have revealed that V815 Her is in fact a four-star system consisting of two close binaries in a long-period orbit. We give preliminary orbital solution for the long-known but unseen "third body" V815 Her `B', which is itself a close eclipsing binary of two M dwarfs. Long-term spot activity of the G dwarf is presented along with the very first Doppler image reconstructions of its spotted surface.

description: We estimated the accuracy of coronal magnetic fields derived from radio observations by comparing them to potential field calculations and the DEM measurements using EUV observations. We derived line of sight component of the coronal magnetic field from polarization observations of the thermal bremsstrahlung in the NOAA active region 11150, observed around 3:00 UT on February 3, 2011 using the Nobeyama Radioheliograph at 17 GHz. Because the thermal bremsstrahlung intensity at 17 GHz includes both chromospheric and coronal components, we extracted only the coronal component by measuring the coronal emission measure in EUV observations. In addition, we derived only the radio polarization component of the corona by selecting the region of coronal loops and weak magnetic field strength in the chromosphere along the line of sight. The upper limit of the coronal longitudinal magnetic fields were determined as 100 - 210 G. We also calculated the coronal longitudinal magnetic fields from the potential field extrapolation using the photospheric magnetic field obtained from the Helioseismic and Magnetic Imager (HMI). However, the calculated potential fields were certainly smaller than the observed coronal longitudinal magnetic field. This discrepancy between the potential and the observed magnetic field strengths can be explained consistently by two reasons; (a) the underestimation of the coronal emission measure resulting from the limitation of the temperature range of the EUV observations, (b) the underestimation of the coronal magnetic field resulting from the potential field assumption.

description: A new synthesised triphenylamine-based dye was anchored to mesoporous pure anatase TiO2 thorough
the OH-ending branch of its first generation dendritic structure. We present the optical properties of the dye-titania
hybrid material and compare its performances with those of the same sensitizer on the commercial Degussa P25,
which contains a rutile phase component. The optical and chemical properties of the dye make it a promising
candidate as a metal-free dye for DSSCs.

description: Recent experimental studies of the multiplicity dependence of heavy quark (HQ) production in proton-proton collisions at 7 TeV showed a strong non-linear increase of the HQ multiplicity as a function of the charged particle multiplicity. We try to understand this behavior using the EPOS3 approach. Two issues play an important role: multiple scattering, in particular its impact on multiplicity fluctuations, and the collective hydrodynamic expansion. The results are very robust with respect to many details of the modeling, which means that these data contain valuable information about very basic features of the reaction mechanism in proton-proton collisions.

description: Traditionally, the introduction of domestic grape in Italy is traced back to a late stage of early Iron Age in relation with the first Greek colonies which settled in southern Italy during 8th–6th centuries BC. However, some recent findings of grape seeds dated in the archaeological contexts of the Middle and Recent Bronze Age suggest that the beginning of grape cultivation in Italy may be anticipated by several centuries. During the excavations carried out in the Terramara di Montale it was possible to recover a large quantity of grape seeds from two stratigraphic contexts dated to the Late Middle Bronze Age (1438-1321 BC) and to beginning of the Recent Bronze Age (1605-1510 BC). A morphological comparison of archaeological pips and modern wild and domestic grapes pips was performed to determine the similarities among them. Digital images of archaeological and modern samples were acquired using a flatbed scanner. The images were processed using the software package ImageJ. A total of 26 morphometric features were measured for each pip. The recorded data were statistically analysed, applying the PCA and LDA, to compare the modern cultivars with the archaeological seeds, which were considered as unidentified samples. The results showed that the archaeological pips found in the two stratigraphic contexts showed a similar morphology to domestic grapes and that only a small percentage were assigned to wild grapes. Morphometric analyses made it possible to obtain valuable information on the management of plant resources between the end of the Middle Bronze and the beginning of the Recent Bronze Age in Emilia. The high percentage of grape seeds identified as domestic would seem to confirm the presence of the domestic grape in Italy already at the end of the 14th and the beginning of the 13th century BC.

description: We report on observations of the neutron star (NS) residing in the low-mass X-ray binary 1RXS J180408.9-34205 taken 2015 March by $\emph{NuSTAR}$ and $\emph{XMM-Newton}$ while the source was in the hard spectral state. We find multiple reflection features (Fe K$_α$ detected with $\emph{NuSTAR}$; N VII, O VII, and O VIII detected in the RGS) from different ionization zones. Through joint fits using the self consistent relativistic reflection model {\sc relxill}, we determine the inner radius to be $\leq 11.1\ R_{g}$. For a 1.4 M$_{\odot}$ NS with a spin of $a_{*}=0$, this is an inner disk radius of $\leq22.2$ km. We find the inclination of the system to be between $18^{\circ}$-$29^{\circ}$. If the disk is truncated at a radius greater than the neutron star radius, it could be truncated by a boundary layer on the neutron star surface. It is also possible that the disk is truncated at the magnetospheric radius; conservative estimates would then imply $B\leq(0.3 -1.0)\times10^{9}$ G at the magnetic poles, though coherent pulsations have not been detected and the source is not identified as a pulsar.

description: We present magnetometry and muon spin rotation ($μ$SR) measurements of the superconducting dichalcogenide Ir$_{0.95}$Pt$_{0.05}$Te$_2$. From both sets of measurements we calculate the penetration depth and thence superfluid density as a function of temperature. The temperature dependence of the superfluid densities from both sets of data indicate fully gapped superconductivity that can be fit to a conventional s-wave model and yiel fitting parameters consistent with a BCS weak coupling superconductor. We therefore see no evidence for exotic superconductivity in Ir$_{0.95}$Pt$_{0.05}$Te$_2$.

Lifetime, collapse and escape paths for hopfions in bulk magnets with competing exchange interactions

description: The lifetimes of magnetic hopfions on a discrete lattice with competing exchange interactions are calculated within the framework of the transition state theory for magnetic degrees of freedom. Three sets of discrete model parameters corresponding to the same continuous micromagnetic model are considered. Minimal energy paths for hopfion collapses were found on the multidimensional energy surface of the system. The activation energies of the collapse processes have been calculated. It turned out that the activation energy differs significantly for the three considered values of the parameters, which indicates the importance of lattice effects, when the hopfion radius equals several lattice constants. Along with the collapse, the hopfion escape process through the sample boundary is studied. It is shown that this process does not require an activation energy. The lifetimes of hopfions are found and it is shown that they can exist only at temperatures of a few kelvins and practically cannot be generated due to thermal fluctuations.

description: Enhancement of electrical properties of PEDOT:PSS thin films were performed by utilizing interaction with polar
solvents (diols: Ethylene Glycol, Diethylene Glycol and Propylene Glycol). Modifications were made by
performing two approaches: addition of diol to water-based PEDOT:PSS solution and by additional soaking of
obtained films in appropriate glycol after drying. In order to determine influence of environmental factors on
sheet resistance, samples were held at room temperature in air and electrical measurements were performed
during the period of 14 days after preparation of samples. Moreover, for freshly prepared samples surface
morphology was determined with AFM measurements in order to get more insight into changes in polymer
arrangements caused by interaction with diols. All modified layers were characterized with much smaller sheet
resistance as compared to reference layer, in some cases even up to almost 3 orders of magnitude, and better
stability with relative degradation rate few times smaller than pristine PEDOT:PSS layer. Moreover some
influence on surface morphology of diol addition was observed. Enhancement of electrical properties is ascribed
to significant modification of polymer ordering in layer caused by differences in solubility in polar solvents for
PEDOT and PSS. Solvent treatment could lead to efficient, all-organic and flexible solar cells.
