description: The application of copper in the CdTe back contact is believed to be crucial to form an ohmic contact
with CdTe, indeed the highest conversion efficiencies have been obtained only with copper insertion. However it is
well known that the devices performance degradation with time is strongly connected to Cu presence. On the other
hand it was actually shown that the carriers collection at the back contact improves as CdTe thickness decreases. We
have prepared devices with identical Cu/Au back contact and different CdTe thickness which ranges from 0.7
microns to 6 microns and then we have performed accelerated lifetime stability tests and dark aging at room
temperature for very long time (up to 16000 h), in order to study the dependency of the performance degradation with
the CdTe thickness. We have analyzed the effects of the aging by current-voltage, capacitance-voltage, drive level
capacitance profiling and admittance spectroscopy in order to address the physical effects connected with the back
contact stability. This study brings out that a possible way to improve the CdTe devices stability is to reduce the
absorber thickness.

description: Quantum topological materials, exemplified by topological insulators, three-dimensional Dirac semimetals and Weyl semimetals, have attracted much attention recently because of their unique electronic structure and physical properties. Very lately it is proposed that the three-dimensional Weyl semimetals can be further classified into two types. In the type I Weyl semimetals, a topologically protected linear crossing of two bands, i.e., a Weyl point, occurs at the Fermi level resulting in a point-like Fermi surface. In the type II Weyl semimetals, the Weyl point emerges from a contact of an electron and a hole pocket at the boundary resulting in a highly tilted Weyl cone. In type II Weyl semimetals, the Lorentz invariance is violated and a fundamentally new kind of Weyl Fermions is produced that leads to new physical properties. WTe2 is interesting because it exhibits anomalously large magnetoresistance. It has ignited a new excitement because it is proposed to be the first candidate of realizing type II Weyl Fermions. Here we report our angle-resolved photoemission (ARPES) evidence on identifying the type II Weyl Fermion state in WTe2. By utilizing our latest generation laser-based ARPES system with superior energy and momentum resolutions, we have revealed a full picture on the electronic structure of WTe2. Clear surface state has been identified and its connection with the bulk electronic states in the momentum and energy space shows a good agreement with the calculated band structures with the type II Weyl states. Our results provide spectroscopic evidence on the observation of type II Weyl states in WTe2. It has laid a foundation for further exploration of novel phenomena and physical properties in the type II Weyl semimetals.

description: We study charge diffusion in relativistic resistive second-order dissipative magnetohydrodynamics. In this theory, charge diffusion is not simply given by the standard Navier-Stokes form of Ohm's law, but by an evolution equation which ensures causality and stability. This, in turn, leads to transient effects in the charge diffusion current, the nature of which depends on the particular values of the electrical conductivity and the charge-diffusion relaxation time. The ensuing equations of motion are of so-called stiff character, which requires special care when solving them numerically. To this end, we specifically develop an implicit-explicit Runge-Kutta method for solving relativistic resistive second-order dissipative magnetohydrodynamics and subject it to various tests. We then study the system's evolution in a simplified 1+1-dimensional scenario for a heavy-ion collision, where matter and electromagnetic fields are assumed to be transversely homogeneous, and investigate the cases of an initially non-expanding fluid and a fluid initially expanding according to a Bjorken scaling flow. In the latter case, the scale invariance is broken by the ensuing self-consistent dynamics of matter and electromagnetic fields. However, the breaking becomes quantitatively important only if the electromagnetic fields are sufficiently strong. The breaking of scale invariance is larger for smaller values of the conductivity. Aspects of entropy production from charge diffusion currents and stability are also discussed.

description: The Cu2ZnSnS4 (CZTS) thin films were prepared by spray pyrolysis method at ambient pressure.
Subsequent annealing of the CZTS layers in vapors of elemental selenium allowed to prepare the Cu2ZnSn(SxSe1-x)4
(CZTSSe) solid solutions. The energy dispersive X-ray analysis as well as Raman scattering investigation confirmed
the formation of solid solution with an anion ratio Se/(S+Se) ≈ 0.33 after annealing in Se-atmosphere. Investigation
of temperature dependence of resistivity yielded the activation character for both CZTS and CZTSSe samples in
whole temperature range of 40 – 300 K. The Mott variable-range hopping conductivity was observed in a large
temperature interval, and its analysis showed that the CZTS film is closer to metal-insulator transition than CZTSSe
film. The glass/ITO/CdS/CZTSSe/Ag structures were prepared by using different deposition methods for different
layers. Optical activity of the CZTSSe layer was demonstrated from the spectral distribution of photoconductivity of
the obtained glass/ITO/CdS/CZTSSe/Ag structure.

description: In our laboratory we fabricate high efficiency CdTe solar cells, exceeding 15 % efficiency, with a low
temperature process, where all the layers are deposited by vacuum evaporation with temperature below 450 °C. The
CdCl2 treatment is typically prepared by putting drops of a methanol solution with a specific concentration of CdCl2.
Starting from a previous work where we studied the effect of the different amount of CdCl2 by changing the methanol
concentration, we have this time analyzed the recrystallization treatment by changing the annealing temperature from
310 °C up to 410 °C in air. By doing so we address the multiple effects that this process has on the material and
device properties for CdTe solar cells.
Activated CdTe layers have been analyzed by means of X-Ray diffraction spectroscopy and atomic force microscopy.
Finished devices with efficiencies from 8% for the low temperature annealing up to more than 14% for the high
temperature ones, have been analyzed by current-voltage, capacitance-voltage and drive level capacitance profiling
techniques, showing that net carrier concentration is dependent with temperature. A detailed analysis of the formation
of intermixed CdS/CdTe layer with temperature is also reported by external quantum efficiency.

description: Context: NOTT (formerly Hi-5) is a new high-contrast L' band (3.5-4.0 \textmu m) beam combiner for the VLTI with the ambitious goal to be sensitive to young giant exoplanets down to 5 mas separation around nearby stars. The performance of nulling interferometers in these wavelengths is affected both by fundamental noise from the background and by the contributions of instrumental noises. This motivates the development of end-to-end simulations to optimize these instruments. Aims: To enable the performance evaluation and inform the design of such instruments on the current and future infrastructures, taking into account the different sources of noise, and their correlation. Methods: SCIFYsim is an end-to-end simulator for single mode filtered beam combiners, with an emphasis on nulling interferometers. It is used to compute a covariance matrix of the errors. Statistical detection tests based on likelihood ratios are then used to compute compound detection limits for the instrument. Results: With the current assumptions on the performance of the wavefront correction systems, the errors are dominated by correlated instrumental errors down to stars of magnitude 6-7 in the L band, beyond which thermal background from the telescopes and relay system becomes dominant. Conclusions: SCIFYsim is suited to anticipate some of the challenges of design, tuning, operation and signal processing for integrated optics beam combiners. The detection limits found for this early version of NOTT simulation with the unit telescopes are compatible with detections at contrasts up to $10^5$ in the L band at separations of 5 to 80 mas around bright stars.

Magnetar Driven Emission in Short Gamma-Ray Bursts

Subjects: Uncategorized

description: Gamma-ray bursts (GRBs) are the brightest astrophysical phenomena in the Universe. The "short" type of GRBs (typically having most of their emission occur over a timescales of less than two seconds) are now widely held to be produced by the merger of a binary neutron star system, though this hypothesis faces a challenge explaining the existence of persistent late-time emission in a subset of short GRBs, referred to as extended emission. An increasingly popular proposal for modelling extended emission is the production of a remnant magnetar from the merger, whose magnetic field, and its interaction with surrounding merger ejecta, powers the late-time luminosity profile. This magnetic propeller model has generally fared well in reproducing long-lasting emission for short GRBs, but has shown itself to have difficulty capturing rapid, late-time flare-like features in the light-curve effectively. This thesis attempts to improve the way in which the magnetic propeller model fits to rapidly-varying observational data. I adopt a two-pronged approach in this endeavour. First, I examine the data processing algorithm commonly used for producing the observational data to which the magnetic propeller model is fit, in order to establish the robustness of the features in the light-curve. In this way, I can evaluate how significant these features are, and the importance of fitting to them. Second, I refine the physical model by adding additional, physically justifiable components aimed at capturing flaring behaviour which does exist within the observational data. This work enhances both the versatility of the magnetic propeller model for short GRBs with extended emission, and the robustness of the observational data to which the physical model is fit.

As the title suggests, the presented material has two foci: Harmonic analysis, more precisely, unique continuation properties of several natural function classes and Schrödinger operators, more precisely properties of their eigenvalues, eigenfunctions and solutions of associated differential equations. It mixes topics from (rather) pure to (rather) applied mathematics, as well as classical questions and results dating back a whole century to very recent and even unpublished ones.

description: This work presents modelling and simulation of CIGS solar modules. The simulations are based on
hybrid model approach, which splits the simulation into two separate models: on the material and on the module
level. The result of using this simulation method is that the module orientation, shape and bending profile could be
completely arbitrary, while keeping the simulation time and computing resources on a reasonable level. The curvature
of the module is simulated by scaling the intensity of the light, based on incident angle of the light ray on each local
point of the module, thus keeping the simple straight geometry in the simulation. The application of the proposed
simulation method was demonstrated on the example of convexly curved 0.5 m2 module, with the east-west
orientation. Specifying the location and day, the daily power yield of such a module can be estimated.

description: Star cluster formation in the early universe and their contribution to reionization remains to date largely unconstrained. Here we present JWST/NIRCam imaging of the most highly magnified galaxy known at z ~ 6, the Sunrise arc. We identify six young massive star clusters (YMCs) with measured radii spanning ~ 20 pc down to ~ 1 pc (corrected for lensing magnification), estimated stellar masses of ~ $10^{(6-7)}$ Msun, and with ages 1-30 Myr based on SED fitting to photometry measured in 8 filters extending to rest-frame 7000A. The resulting stellar mass surface densities are higher than 1000 Msun pc$^{-2}$ (up to a few $10^5$ Msun pc$^{-2}$) and their inferred dynamical ages qualify the majority of these systems as gravitationally-bound stellar clusters. The star cluster ages map the progression of star formation along the arc, with to evolved systems (>~ 10 Myr old) followed by very young clusters. The youngest stellar clusters (< 5 Myr) show evidence of prominent Hbeta + [OIII]4959,5007 emission, based on photometry, with equivalent widths larger than 1000 A rest-frame, and are hosted in a 200 pc sized star-forming complex. Such a region dominates the ionizing photon production, with a high efficiency log($ξ_{ion}$ [Hz erg$^{-1}$]) ~ 25.7. A significant fraction of the recently formed stellar mass of the galaxy (> 10-30 %) occurred in these YMCs. We speculate that such sources of ionizing radiation boost the ionizing photon production efficiency which eventually carve ionized channels that might favor the escape of Lyman continuum radiation. The survival of some of the clusters would make them the progenitors of massive and relatively metal-poor globular clusters in the local Universe.

description: We discuss the formation and evolution of systems comprised of a low-mass ($M_\star \lesssim 4 \, \rm M_\odot$) main sequence star, orbiting a $10^5-10^7 \, \rm M_\odot$ supermassive black hole with an orbital period of order $\sim$hours, and a mild eccentricity ($e\approx0.1-0.2$), episodically shedding mass at each pericenter passage. We argue that the resulting mass transfer is likely unstable, with Roche lobe overflow initially driven by gravitational wave emission, but then being accelerated by the star's expansion in response to its mass loss, undergoing a runaway process. We show that such systems are naturally produced by two-body gravitational encounters within the inner parsec of a galaxy, followed by gravitational wave circularization and inspiral from initially highly eccentric orbits. We argue that such systems can produce recurring flares similar to the recently identified class of X-ray transients known as Quasi-Periodic Eruptions, observed at the centers of a few distant galaxies.

description: Overall application of inexpensive, non-vacuum chemical (CBD) and electrochemical deposition
(ECD) techniques that can be scaled-up to industrial processes is targeted for processing the absorber-, buffer-, and
window-layer of CISe/CIGSe TFSCs to overcome current process incompatibilities mainly resulting from the
simultaneous use of moderate temperature non-vacuum (50-70oC) and high temperature (500-700oC) vacuum
processes. Low cost ECD processing of ternary CuInSe2 and quaternary Cu(In,Ga)Se2 chalcopyrite semiconductor
films with crystal quality similar to that of PVD grown films was achieved by as few as possible process steps
skipping selenization at elevated temperatures. Chalcopyrite phase formation was confirmed already in as-deposited
films. The film quality was further improved by subsequent annealing at 300oC, for 2h, in N2. ZnSe buffer- and ZnO
window-layers were processed by CBD and ECD techniques, respectively. The properties of n-ZnO/i-ZnO bilayer
were thoroughly investigated with respect to layer thickness and dopant concentration. By successive integration of
low cost ECD ZnO/CBD ZnSe buffer and window components in CISe/CIGSe solar cells with absorbers grown by
standard vacuum techniques, the respective p-n junctions exhibited I-V characteristics competing with
monocrystalline silicon(c-Si) I-V.

description: Cu2ZnSnS4 (CZTS) as an absorber layer is a potential candidate in thin film solar cell application being a p-type material with a band gap of 1.45 eV. CZTS thin film was successfully deposited on soda lime glass substrate at 350ºC by spray technique with an additional feature of the application of an electric field. An electric field was created by applying DC voltage (700 V) to the nozzle during the spray deposition. X-ray diffraction pattern revealed that the CZTS film exhibited pure Kesterite structure. The presence of electric field during spray was found to enhance the crystallinity of deposited CZTS film. Enhancement in the optical absorption of CZTS film was also seen and the electrical measurment showed p- type conductivity in the films with with enhancement in the mobility. For the applied voltage = 0 V, the resistivity is equal to 0.25 Ω-cm, carrier concentration 1.3 ×1018 cm-3 and mobility ~19.19 cm2 V-1 s-1. On the other hand, the CZTS film deposited at 700 V showed the decrement in the resistivity to 0.12 Ω-cm, carrier concentration 1.23×1018 cm-3 and increased mobility ~ 42.26 cm2 V-1 s-1.

description: CdTe thin film solar cells provide a good opportunity for low cost photovoltaic modules. To obtain highly efficient solar cells with a CdS/CdTe hetero junction an activation treatment in chlorine containing atmosphere is necessary. The common way is a CdCl2 deposition as wet solution on top of the CdTe layer followed by thermal annealing at 350-430°C. An Additional activation method is a treatment with HCl-containing gas and simultaneously thermal annealing in the same temperature range. In this experiments, efficiencies up to 8.7% could be obtained by using a gas mixture of 2% HCl and 98% N2. The reference process with CdCl2 leads to efficiencies up to 11.8%. Here no intentional Cu-treatment was applied. The two activation methods causes distinct differences in den chlorine content of the treated CdTe layers. The analyses contain I-V and EQE characterization, FE-SEM cross sections and RF GD-OES depth profiling.

description: The ecological impacts of invasive mammals are widely documented around the world. In New Zealand, fencing designed to exclude non-native mammals is used for conservation and restoration efforts. The Orokonui Ecosanctuary is a 307-hectare coastal Otago reserve (Dunedin, New Zealand) that is surrounded by mammal-exclusion fencing. The goal of the present study was to investigate how excluding mammals and including (native) animals inside the Orokonui Ecosanctuary fence has influenced ground- and litter-dwelling beetle (Coleoptera) abundance, diversity, and community composition. We hypothesised that beetle abundance, diversity, and community composition would be different whether the beetles sampled were from sites inside the fence or outside the fence. Beetles were extracted from the litter and soil of six sites (three inside, three outside) two times (once in winter, once in summer). The abundance, diversity, species composition, size distribution, and trophic guild distribution of beetles inside and outside the fence and between seasons were compared. Our results suggest that sites inside the fence harbour a greater abundance and diversity of beetles. We found a high abundance of native beetles both inside and outside the Orokonui Ecosanctuary’s fence. Further research may find evidence that the fenced sanctuary is providing a ‘halo effect’ whereby native beetles thriving within the Orokonui Ecosanctuary are spreading out into the surrounding landscape and also outcompeting introduced beetles.

description: Ternary compound Cu2SnS3 (CTS) thin films were grown by thermal evaporation on soda lime glass
/Mo substrates. Following deposition, the films were annealed at 570 ºC for 5 min, with sulfur. For the CTS film
annealed with sulfur instead of via the CBD-CdS process, an intrinsic ZnO buffer layer was deposited by RF
sputtering. The photovoltaic cells with the structure glass/Mo/CTS/ZnO/ZnO:Al/Al were fabricated. After annealing
in air at 150 ºC for 30 min, the conversion efficiency of the photovoltaic cells was found to have been enhanced, and
the photovoltaic cell with the best efficiency exhibited an open-circuit voltage of 172 mV, a short-circuit current
density of 29.4 mA/cm2, a fill factor of 0.377, and a conversion efficiency of 1.9%. It is thought that the efficiency
improvement resulting from this heat treatment was due to the minimization of sputtering damage at the CTS/ZnO
interface.

Via comparison with recent numerically exact simulations, we show that such methods accurately capture the long-time non-equilibrium quench dynamics. The two parameters that must be controlled in these tensor network influence functional approaches are a time discretization (Trotter) error and a bond dimension (tensor network truncation) error. We show that the actual numerical uncertainties are controlled by an intricate interplay of these two approximations which we demonstrate in different regimes. Our work opens the door to using these tensor network influence functional methods as general impurity solvers.

description: In this study, thin film solar cells having Mo/CIS/Ag-InS/ZnO/AZO/Ag/AZO/Ni/Al structure were
fabricated. Structural, optical and electrical properties of spray pyrolyzed copper indium sulfide (CIS) and silver
doped indium sulfide (Ag-InS) films with various thicknesses were investigated. Moreover, photovoltaic device
performances were analyzed as a function of the buffer layer thickness. With this study for the first time, we have
introduced a new sandwich structured transparent conductive oxide (TCO) layer for inorganic solar cells. The
maximum photo conversion efficiency, which was 1.16 %, obtained in our study was very promising among the thin
film solar cells deposited via wet chemical methods.

description: Highly transparent and highly resistive i-ZnO layers have been prepared with pulsed DC magnetron
sputtering using a vertical lab coater tool equipped with a dual rotary magnetron sputtering source. A single 900 mm
ceramic i-ZnO target, which is commercial available, has been used. We provide evidence that unipolar pulsed DC
sputtering can offer an alternative to the more established RF-process for depositions of i-ZnO films. The process
stability has been optimized in order to obtain the best compromise between a low arcing process and a high
deposition rate. The dependency of film parameters on the variation of deposition parameters such as target power,
gas mixture and temperature was characterized by atomic force microscopy, electrical and optical methods. The
estimated band gap for the deposited films has been determined by Tauc method. The results exhibit good properties,
demonstrating advantages of i-ZnO films deposited by the presented method.

description: Semiconductors compound as Cu2SnS3 (CTS) with cheap and more available elements are getting more and more interest. Its low bandgap makes it suitable as absorber in the long wavelength region in solar cell with heterojunction structure. In this work CTS thin films are grown by two-steps processes: precursor deposition by co-sputtering of CuS and SnS, followed by a thermal treatment in sulphur atmosphere. A first optimization of this process allowed to make a CTS based solar cell exhibiting short circuit current density (Jsc), open circuit voltage (Voc), and fill factor (FF) of 29.7 mA/cm2, 0.219 V as well as a total-area power-conversion efficiency of 2.37%. Furthermore the External Quantum Efficiency (EQE) curve at wavelength higher than 1200 nm has values higher than 10%.

description: We theoretically study a vibrating pair of parallel electrodes bridged by a (deformed) liquid droplet, which is a recently developed microfluidic device to harvest vibrational energy. The device can operate with various liquids, including liquid metals, electrolytes, as well as ionic liquids. We numerically solve the Young-Laplace equation for all droplet shapes during a vibration period, from which the time-dependent capacitance follows that serves as input for an equivalent circuit model. We first investigate two existing energy harvesters (with a constant and a vanishing bias potential), for which we explain an open issue related to their optimal electrode separations, which is as small as possible or as large as possible in the two cases, respectively. Then we propose a new engine with a time-dependent bias voltage, with which the harvested work and the power can be increased by orders of magnitude at low vibration frequencies and by factors 2-5 at high frequencies, where frequencies are to be compared to the inverse RC-time of the circuit.

description: This study examines the enhanced photoelectric conversion observed in Cu(In,Ga)Se2 (CIGS) solar cells with a flexible polydimethylsiloxane (PDMS) antireflection layer (ARL) with embedded ZnO nanorods fabricated using an aqueous solution method. The cell with the PDMS antireflection layer with embedded ZnO nanorods enhance the short-circuit current density from 18.27 to 21.12 mA/cm2 under a simulated one-sun condition. Because of the sun’s movement, the broadband and omnidirectional light harvesting is important. Therefore, the omnidirectional anti-reflection of CIGS solar cells with the various ARL is also investigated.

description: Compound semiconductor materials of Cu2–II–IV–VI4 family, like Cu2ZnSnS4 (CZTS) and
Cu2ZnSnSe4 (CZTSe), are attracting interest of researchers for making thin film photovoltaic devices. In this work,
we report a study of substituting Sn with Ge to make Cu2ZnSnxGe1-xS4 (CZTGS) thin films. The method of
sulfurizing sputtering-deposited metal precursors has been applied in preparing these CZTGS samples. A series of
films with different Ge/(Ge+Sn) ratios have been investigated for structural, optical and electrical properties. X-ray
diffraction (XRD), Raman and scanning electron microscopy (SEM) characterisation show gradual change of film
structural properties when increasing Ge/(Ge+Sn) ratio. Optical band gaps of CZTGS thin films with different Ge
content were derived from their quantum efficiency (QE) measurement. Cu2ZnGeS4 (CZGS) thin film solar cell was
manufactured from the fabricated absorber film. Photovoltaic characterisation reveals the scope for further improving
CZGS cell performance.
Squeezing and overcoming the Heisenberg scaling with spin-orbit coupled quantum gases

description: We predict that exploiting spin-orbit coupling in a harmonically trapped spinor quantum gas can lead to scaling of the optimal measurement precision beyond the Heisenberg scaling. We show that quadratic scaling with the number of atoms can be facilitated via squeezed center-of-mass excitations of the atomic motion using a 1D spin-orbit coupled fermions or strongly interacting bosons (Tonks-Girardeau gas). Based on predictions derived from analytic calculations of the corresponding quantum Fisher information, we then introduce a protocol which overcomes the Heisenberg scaling (and limit) with help of a tailored excited and entangled many-body state of a non-interacting Bose-Einstein condensate. We identify corresponding optimal measurements and argue that even finite temperature as a source of decoherence is, in principle, rather favorable for the obtainable precision scaling.

Spectrum Efficiency Enhancement for Wireless Communications with Reconfigurable Metasurfaces
Creators: name: Fang, Sisai
Publisher: name: University of Leicester

Subjects: Uncategorized

description: Reconfigurable metasurfaces are gaining more and more interests in both academia and industry in recent years. They are constructed by numerous elements, each element can reflect or refract signals from transmitters, thereby enhancing or suppressing the signals at receivers. The energy cost of reconfigurable metasurfaces is negligible since the elements are passive and the main consumption is from controllers, in addition, they are portable because of the compact sizes. With the aforementioned benefits, in this work, reconfigurable metasurfaces are explored in various communication scenarios such as unmanned aerial vehicle (UAV) communication, dual-function radar communication (DFRC), full-duplex (FD) communication to boost spectrum efficiency. Firstly, UAV communication which enjoys the unique advantages such as high agility and energy-green is prone to interception from eavesdroppers due to line-of-sight channels. Therefore, the potentials of reconfigurable metasurfaces are exploited in UAV-assisted communication networks in the perspective of physical layer security. Importantly, a closedform solution is originally obtained for such networks. In addition, this is the first work that considers the secrecy issues for DFRC systems in the presence of reconfigurable metasurfaces. One of the main contributions is that low computational complexity algorithms for such systems are developed to boost both detection and communication abilities, effectively addressing the spectrum scarcity problem. Finally, dual-side reconfigurable metasurfaces have been investigated in FD communication to tackle the main challenge for implementation, namely self-interference, as devices send and receive signals simultaneously. Specifically, the self-interference is mitigated by the reflection feature of the reconfigurable metasurfaces and the refraction feature helps to enhance transmission, which proposes a novel self-interference cancellation scheme to facilitate FD communication.

description: We present a study of the degradation of thin-film CIGS material in the vicinity of P2 phase-transformation type
of laser scribes. They comprised optical microscopy, scanning electron microscopy, energy dispersive X-ray spectroscopy,
photoluminescence and Raman spectroscopy. While the optical and electron microscopy measurements have shown a clear
change of the morphological properties of CIGS including removal, melting and dislocation of material from the area scribed
by the laser, the X-ray analysis revealed an accumulation of O, Zn, Ga, and Cu elements in the melted phase and an
evaporation of more volatile In atoms from the region of visually changed CIGS. At the same time Raman and
photoluminescence measurements have shown substantial alteration of semiconductor material properties, i.e. of the
crystallinity and the bandgap energy even far beyond of this region. More precisely, the amplitudes of the A1 and B2,E
Raman peaks were found to increase continuously with increasing distance from the P2 scribes, reaching the distances of
approximately three times the 3 diameter of the beam. A similar tendency was also observed for photoluminescence signals,
that additionally revealed a systematic shift of the bandgap energy in CIGS as estimated from the maximum of the emission
spectrum. Our results indicate that the phase-transformation scribing generates changes in thin-film CIGS material far beyond
the heat affected zone. As such they can help to decide on optimal spacing between P1-P3 scribes and thus reduce a "dead
area" of thin-film CIGS solar cells.
