description: For a-Si/μc-Si based solar cells, effective light trapping, specifically in the long wavelength range, is
of decisive importance towards demonstrating stabilized module efficiencies of 10% and beyond. Since
commercially available F-doped SnO2 coatings on glass are reaching their limits here, Applied Materials has
developed a large area sputtering based front transparent conductor solution meeting the challenging targets of the
industry on module performance, cost effectiveness and flexibility in terms of tunability for best performance on
different absorber layer stacks. To date, we repeatably achieved stabilized module efficiencies of 10.2% stable on
Gen5 (1.4 m²) a-Si/μc-Si based modules with this technology. This would result in 10.5% projected efficiency on
Gen8.5 (5.7 m²). Gen8.5 modules with 596 W initial powers were recently demonstrated as a first step in the process
transfer from Gen5 to Gen8.5.

description: We successfully fabricated zinc oxide (ZnO) films with a very high haze value and low resistivity
using metal-organic chemical vapor deposition (MOCVD) and by carrying out glass-substrate etching before film
deposition. Effects of glass-substrate etching time on ZnO film properties were systematically investigated. It was
found that the surface morphology of ZnO films can be modified by varying the glass etching time, with an increase
in the glass etching time, the surface morphology of ZnO films changed from conventional pyramid-like single
texture to cauliflower-like double texture. Further, the rms roughness and haze value of the films increased
remarkably. Using newly developed ZnO films with a high haze value as front transparent conducting oxide (TCO)
film in hydrogenated amorphous silicon (a-Si:H) solar cells, we improved the quantum efficiency of these cells
remarkably in the long-wavelength region. Therefore, the obtained ZnO films have considerable potentials for use as
front TCO films in thin film silicon solar cells.

description: Virtually all known exoplanets reside around stars with $M<2.3~M_\odot$; to clarify if the dearth of planets around more massive stars is real, we launched the direct-imaging B-star Exoplanet Abundance STudy (BEAST) survey targeting B stars ($M>2.4~M_\odot$) in the young (5-20 Myr) Scorpius-Centaurus association (Sco-Cen). Here we present the case of a massive ($M \sim 9~M_\odot$) BEAST target, $μ^2$ Sco. Based on kinematic information, we found that $μ^2$ Sco is a member of a small group which we label Eastern Lower Scorpius, refining in turn the precision on stellar parameters. Around this star we identified a robustly detected substellar companion ($14.4\pm 0.8 M_J$) at a projected separation of $290\pm 10$ au, and a probable second object ($18.5\pm 1.5 M_J$) at $21\pm 1$ au. The planet-to-star mass ratios of these objects are similar to that of Jupiter to the Sun, and their irradiation is similar to those of Jupiter and Mercury, respectively. The two companions of $μ^2$ Sco are naturally added to the giant planet b Cen b recently discovered by BEAST; although slightly more massive than the deuterium burning limit, their properties resemble those of giant planets around less massive stars and they are better reproduced by a formation under a planet-like, rather than a star-like scenario. Irrespective of the (needed) confirmation of the inner companion, $μ^2$ Sco is the first star that would end its life as a supernova that hosts such a system. The tentative high frequency of BEAST discoveries shows that giant planets or small-mass brown dwarfs can form around B stars. When putting this finding in the context of core accretion and gravitational instability, we conclude that the current modeling of both mechanisms is not able to produce this kind of companion. BEAST will pave the way for the first time to an extension of these models to intermediate and massive stars. (abridged)

description: This article deals with the problem of the contact between dielectric layers and aluminium on the rear side of solar cells and its impact on the passivation effect. Several dielectric layers and stacks of PECVD silicon nitride and silicon oxide have been deposited on monocrystalline and multicrystalline wafers to study their passivation behaviours. Solar cells were also elaborated with a dielectric/aluminium structure on the back side and a set of wafers was used to highlight the influence of aluminium capping dielectric layers on passivation. Although it is reported that all structures give similar passivations when composed of one layer of silicon nitride at least, capping them with aluminium degrades the passivation below the standard aluminium BSF except for the SiNr/SiN stacks which is only slightly degraded. Consequently, solar cells are not as good as full aluminium coverage cells and it is found that the minority carrier lifetime and the internal quantum efficiency results are in contradiction with the I (V) results. This fact entails the need of performing complete solar cells to study the rear passivation by dielectric layers.

description: Adequate sleep and physical activity have been linked to the overall well-being of both medical and psychiatric patients. Patients with schizophrenia have shown abnormal sleep patterns and decreased physical activity that were linked to their psychopathology and physical health. These phenomena are not studied yet in Arab patients with schizophrenia. The purpose of this study is to study the sleep and exercise patterns in Arab patients with schizophrenia compared with those of healthy controls. A total of 99 patients with schizophrenia and 101 controls were recruited. Arabic versions of sleep, exercise, socio-demographic, and clinical questionnaires were administered as well as the validated scales to measure psychopathology, depression, and suicidality in these participants. The majority of patients with schizophrenia slept more than 8 h per day and exercised less when compared with controls. Sleep quality was worse in those with higher depression score and higher suicidality scores were seen in patients with lower sleep duration. Multinomial regression showed that patients with schizophrenia have higher odds of sleeping more than 8 h even after controlling for the intake of antipsychotics, age, gender, smoking status, and other confounding factors. Our results showed that Arab patients with schizophrenia are at increased risk of having longer sleep duration with inadequate physical activity, which are correlating with worsening of depressive symptoms and suicidality. Thus, more attention should be paid to the changes in sleep patterns and level of exercise when treating Arab patients with schizophrenia.Other Information Published in: International Journal of Behavioral Medicine

Spin Hall Effect in a Spinor Dipolar Bose-Einstein Condensate

Year: 2016
Subjects: subject: Quantum Gases (cond-mat.quant-gas)

description: We theoretically show that the spin Hall effect arises in a Bose-Einstein condensate (BEC) of neutral atoms interacting via the magnetic dipole-dipole interactions (MDDIs). Since the MDDI couples the total spin angular momentum and the relative orbital angular momentum of two colliding atoms, it works as a spin-orbit coupling. Thus, when we prepare a BEC in a magnetic sublevel $m=0$, thermally and quantum-mechanically excited atoms in the $m=1$ and $-1$ states feel the Lorentz-like foces in the opposite directions. This is the origin for the emergence of the the spin Hall effect. We define the mass-current and spin-current operators from the equations of continuity and calculate the spin Hall conductivity from the off-diagonal current-current correlation function within the Bogoliubov approximation. We find that the correction of the current operators due to the MDDI significantly contributes to the spin Hall conductivity. Possible experimental situation is also discussed.

description: The two-dimensional $q$-state clock model for $q \geq 5$ undergoes two Berezinskii-Kosterlitz-Thouless (BKT) phase transitions as temperature decreases. Here we report an extensive worm-type simulation of the square-lattice clock model for $q=$5--9 in a pair of flow representations, from the high- and low-temperature expansions, respectively. By finite-size scaling analysis of susceptibility-like quantities, we determine the critical points with a precision improving over the existing results. Due to the dual flow representations, each point in the critical region is observed to simultaneously exhibit a pair of anomalous dimensions, which are $η_1=1/4$ and $η_2 = 4/q^2$ at the two BKT transitions. Further, the approximate self-dual points $β_{\rm sd}(L)$, defined by the stringent condition that the susceptibility like quantities in both flow representations are identical, are found to be nearly independent of system size $L$ and behave as $β_{\rm sd} \simeq q/2π$ asymptotically at the large-$q$ limit. The exponent $η$ at $β_{\rm sd}$ is consistent with $1/q$ within statistical error as long as $q \geq 5$. Based on this, we further conjecture that $η(β_{\rm sd}) = 1/q$ holds exactly and is universal for systems in the $q$-state clock universality class. Our work provides a vivid demonstration of rich phenomena associated with the duality and self-duality of the clock model in two dimensions.

description: Blood and urine cadmium levels have been found to be positively associated with hyperuricemia (HU) in some studies. Few studies have examined the association between dietary cadmium intake, dietary patterns and HU in the Chinese population. The study analysed data from 8429 adults who participated in the China Health and Nutrition Survey (CHNS). Dietary intake was assessed by 3-day 24 h food record in seven waves of survey (1991, 1993, 1997, 2000, 2004, 2006 and 2009). Serum uric acid was measured in 2009. Dietary pattern was identified using factor analysis. The association between cumulative dietary cadmium intake, dietary patterns and HU was assessed using logistic regression. In total, 1737 (16.3%) participants had HU in the study sample. After adjusting for demographic, lifestyle factors (i.e. smoking, alcohol drinking, physical activity) and chronic conditions, the OR for HU was 2.25 (95%CI 1.84–2.77, p for trend < 0.001) for extreme quartiles of estimated cumulative cadmium intake. A traditional southern dietary pattern characterized by high intake of rice, pork, fish and vegetables, and low intake of wheat was associated with three times increased prevalence of HU; comparing the extreme quartiles, the odds ratio (OR) was 3.24 (95%CI 2.61–4.01). No association between the modern dietary pattern (high intake of fruit, soymilk, egg, milk and deep fried products) and HU was found. In conclusion, traditional southern dietary pattern and cadmium intake are positively associated with hyperuricemia among Chinese adults.Other Information Published in: Exposure and Health

description: We examine Kepler light curve variability on habitable zone transit timescales for a large uniform sample of spectroscopically studied Kepler exoplanet host stars. The stars, taken from Everett et al. (2013) are solar-like in their properties and each harbors at least one exoplanet (or candidate) of radius $\le$2.5\re. The variability timescale examined is typical for habitable zone planets orbiting solar-like stars and we note that the discovery of the smallest exoplanets ($\le$1.2\re) with corresponding transit depths of less than $\sim$0.18 mmag, occur for the brightest, photometrically quietest stars. Thus, these detections are quite rare in $Kepler$ observations. Some brighter and more evolved stars (subgiants), the latter which often show large radial velocity jitter, are found to be among the photometrically quietest solar-like stars in our sample and the most likely small planet transit hunting grounds. The Sun is discussed as a solar-like star proxy to provide insights into the nature and cause of photometric variability. It is shown that $Kepler's$ broad, visible light observations are insensitive to variability caused by chromospheric activity that may be present in the observed stars.

description: Iwasawa theory of Heegner points on abelian varieties of GL_2 type has been studied by, among others, Mazur, Perrin-Riou, Bertolini and Howard. The purpose of this paper is to describe extensions of some of their results in which abelian varieties are replaced by the Galois cohomology of Deligne's p-adic representation attached to a modular form of even weight >2. In this setting, the role of Heegner points is played by higher-dimensional Heegner-type cycles that have been recently defined by Bertolini, Darmon and Prasanna. Our results should be compared with those obtained, via deformation-theoretic techniques, by Fouquet in the context of Hida families of modular forms.

description: We present an online algorithm to deal with pattern matching in strings. The problem we investigate is commonly known as string matching with mismatches in which the objective is to report the number of characters that match when a pattern is aligned with every location in the text. The novel method we propose is based on the frequencies of individual characters in the pattern and the text. The algorithm consumes minimal space in the form of simple arrays, which reduces the cost overhead to maintain the complex data structures such as suffix trees or automaton.

description: Aggression in children is frequent during the early years of childhood. Among children with psychiatric disorders in general, and autism in particular, challenging behaviours and aggression rates are higher. These can take on different forms, such as hitting, kicking, and throwing objects. Social robots that are able to detect undesirable interactions within its surroundings can be used to target such behaviours. In this study, we evaluate the performance of five machine learning techniques in characterizing five possible undesired interactions between a child and a social robot. We examine the effects of adding different combinations of raw data and extracted features acquired from two sensors on the performance and speed of prediction. Additionally, we evaluate the performance of the best developed model with children. Machine learning algorithms experiments showed that XGBoost achieved the best performance across all metrics (e.g., accuracy of 90%) and provided fast predictions (i.e., 0.004 s) for the test samples. Experiments with features showed that acceleration data were the most contributing factor on the prediction compared to gyroscope data and that combined data of raw and extracted features provided a better overall performance. Testing the best model with data acquired from children performing interactions with toys produced a promising performance for the shake and throw behaviours. The findings of this work can be used by social robot developers to address undesirable interactions in their robotic designs.Other Information Published in: International Journal of Social Robotics

description: The quality of a companion robot’s reaction is important to make it acceptable to the users and to sustain interactions. Furthermore, the robot’s reaction can be used to train socially acceptable behaviors and to develop certain skills in both normally developing children and children with cognitive disabilities. In this study, we investigate the influence of reaction time in the emotional response of a robot when children display aggressive interactions toward it. Different interactions were considered, namely, pickup, shake, drop and throw. The robot produced responses as audible sounds, which were activated at three different reaction times, namely, 0.5 s, 1.0 s, and 1.5 s. The results for one of the tasks that involved shaking the robotic toys produced a significant difference between the timings tested. This could imply that producing a late response to an action (i.e. greater than 1.0 s) could negatively affect the children’s comprehension of the intended message. Furthermore, the response should be comprehensible to provide a clear message to the user. The results imply that the designers of companion robotic toys need to consider an appropriate timing and clear modality for their robots’ responses.Other Information Published in: International Journal of Social Robotics

description: In this paper we present the technical evolution of rear contacted amorphous/crystalline silicon heterojunction (RECASH) and point-RECASH (PRECASH) solar cells. The results are compared to a conventionally front contacted silicon heterojunction solar cell (SHJ). We characterised the solar cells by means of dark and illuminated I-V characteristics, external and internal quantum efficiencies and QSSPC measurements. Higher shortcircuit current densities and internal quantum efficiencies compared to the reference have been reached, proving the higher short-circuit current density potential of RECASH and PRECASH solar cells.

description: Cancer Stem Cells/Cancer Initiating Cells (CSCs/CICs) is a rare sub-population within a tumor that is responsible for tumor formation, progression and resistance to therapies. The interaction between CSCs/CICs and tumor microenvironment (TME) can sustain “stemness” properties and promote their survival and plasticity. This cross-talk is also pivotal in regulating and modulating CSC/CIC properties. This review will provide an overview of the mechanisms underlying the mutual interaction between CSCs/CICs and TME. Particular focus will be dedicated to the immunological profile of CSCs/CICs and its role in orchestrating cancer immunosurveillance. Moreover, the available immunotherapy strategies that can target CSCs/CICs and of their possible implementation will be discussed. Overall, the dissection of the mechanisms regulating the CSC/CIC-TME interaction is warranted to understand the plasticity and immunoregulatory properties of stem-like tumor cells and to achieve complete eradications of tumors through the optimization of immunotherapy.Other Information Published in: Cancer Microenvironment

description: Analysis of transit times in exoplanetary systems accurately provides an instantaneous orbital period, $P(t)$, of their member planets. A long-term monitoring of those transiting planetary systems puts limits on the variability of $P(t)$, which are translated into the constraints on the time variation of the gravitational constant $G$. We apply this analysis to $10$ transiting systems observed by the Kepler spacecraft, and find that $ΔG/G\lesssim 5\times10^{-6}$ for 2009-2013, or $\dot{G}/G \lesssim 10^{-6}\,\mathrm{yr}^{-1}$ if $\dot{G}$ is constant. While the derived limit is weaker than those from other analyses, it is complementary to them and can be improved by analyzing numerous transiting systems that are continuously monitored.

description: We report single crystal growth of the series of CeTAl$_3$ compounds with T = Cu, Ag, Au, Pd and Pt by means of optical float zoning. High crystalline quality was confirmed in a thorough characterization process. With the exception of CeAgAl$_3$, all compounds crystallize in the non-centrosymmetric tetragonal BaNiSn$_{3}$ structure (space group: I4mm, No. 107), whereas CeAgAl$_3$ adopts the related orthorhombic PbSbO$_2$Cl structure (Cmcm, No. 63). An attempt to grow CeNiAl$_3$ resulted in the composition CeNi$_2$Al$_5$. Low temperature resistivity measurements down to $\sim$0.1K did not reveal evidence suggestive of magnetic order in CePtAl$_3$ and CePdAl$_3$. In contrast, CeAuAl$_3$, CeCuAl$_3$ and CeAgAl$_3$ display signatures of magnetic transitions at 1.3K, 2.1K and 3.2K, respectively. This is consistent with previous reports of antiferromagnetic order in CeAuAl$_3$, and CeCuAl$_3$ as well as ferromagnetism in CeAgAl$_3$, respectively.

description: We derive the cross-section for exclusive vector meson production in high energy deeply inelastic scattering off a deuteron target that disintegrates into a proton and a neutron carrying large relative momentum in the final state. This cross-section can be expressed in terms of a novel gluon Transition Generalized Parton Distribution (T-GPD); the hard scale in the final state makes the T-GPD sensitive to the short distance nucleon-nucleon interaction. We perform a toy model computation of this process in a perturbative framework and discuss the time scales that allow the separation of initial and final state dynamics in the T-GPD. We outline the more general computation based on the factorization suggested by the toy computation: in particular, we discuss the relative role of "point-like" and "geometric" Fock configurations that control the parton dynamics of short range nucleon-nucleon scattering. With the aid of exclusive $J/Ψ$ production data at HERA, as well as elastic nucleon-nucleon cross-sections, we estimate rates for exclusive deuteron photo-disintegration at a future Electron-Ion Collider (EIC). Our results, obtained using conservative estimates of EIC integrated luminosities, suggest that center-of-mass energies $s_{NN}\sim 12$ GeV$^2$ of the neutron-proton subsystem can be accessed. We argue that the high energies of the EIC can address outstanding dynamical questions regarding the short-range quark-gluon structure of nuclear forces by providing clean gluon probes of such "knockout" exclusive reactions in light and heavy nuclei.

description: We investigate the wave packet dynamics of a pair of particles that undergoes a rapid change of scattering length. The short-range interactions are modeled in the zero-range limit, where the quench is accomplished by switching the boundary condition of the wave function at vanishing particle separation. This generates a correlation wave that propagates rapidly to nonzero particle separations. We have derived universal, analytic results for this process that lead to a simple phase-space picture of the quench-induced scattering. Intuitively, the strength of the correlation wave relates to the initial contact of the system. We find that, in one spatial dimension, the $k^{-4}$ tail of the momentum distribution contains a ballistic contribution that does not originate from short-range pair correlations, and a similar conclusion can hold in other dimensionalities depending on the quench protocol. We examine the resultant quench-induced transport in an optical lattice in 1D, and a semiclassical treatment is found to give quantitatively accurate estimates for the transport probabilities.

description: The quasi-deuteron model introduced by Levinger is used to explain cross sections for knocking out high-momentum protons in photo-absorption on nuclei. This is within a framework we characterize as exhibiting high renormalization group (RG) resolution. Assuming a one-body reaction operator, the nuclear wave function must include two-body short-range correlations (SRCs) with deuteron-like quantum numbers. In a previous paper, we showed that SRC physics can be naturally accounted for at low RG resolution. Here we describe the quasi-deuteron model at low RG resolution and determine the Levinger constant, which is proportional to the ratio of nuclear photo-absorption to that for photo-disintegration of a deuteron. We extract the Levinger constant based on the ratio of momentum distributions at high relative momentum. We compute momentum distributions evolved under similarity RG (SRG) transformations, where the SRC physics is shifted into the operator as a universal two-body term. The short-range nature of this operator motivates using local-density approximations with uncorrelated wave functions in evaluating nuclear matrix elements, which greatly simplifies the analysis. The operator must be consistently matched to the RG scale and scheme of the interaction for a reliable extraction. We apply SRG transformations to different nucleon-nucleon (NN) interactions and use the deuteron wave functions and Weinberg eigenvalues to determine approximate matching scales. We predict the Levinger constant for several NN interactions and a wide range of nuclei comparing to experimental extractions. The predictions at low RG resolution are in good agreement with experiment when starting with a hard NN interaction and the initial operator. Similar agreement is found using soft NN interactions when the additional two-body operator induced by evolution from hard to soft is included.

description: We have fabricated 4-element Graphene/Silicon on Insulator (SOI) based Schottky barrier photodiode array ()PDA and investigated its optoelectronic device performance. In our device design, monolayer graphene is utilized as common electrode on lithographically defined linear array of n-type Si channels on SOI substrate. As revealed by wavelength resolved photocurrent spectroscopy measurements, each element in the PDA structure exhibited a maximum spectral responsivity comparable to that of commercially available photodiodes operating under self-powered operational mode. Time-dependent photocurrent spectroscopy measurements showed excellent photocurrent reversibility of the device. The study presented here is expected to offer exciting opportunities in terms of high value-added graphene/Si based PDA device applications such as multi-wavelength light measurement, level metering, high-speed photometry, position/motion detection, and more.

description: We investigate a restriction of Paul Erdos' well-known problem from 1936 on the discrepancy of homogeneous arithmetic progressions. We restrict our attention to a finite set S of homogeneous arithmetic progressions, and ask when the discrepancy with respect to this set is exactly 1. We answer this question when S has size four or less, and prove that the problem for general S is NP-hard, even for discrepancy 1.
Solving the income-happiness paradox

description: Easterlin notes a contradiction in the data. While the cross-sectional data set shows that happiness is a positive monotonic function of income, the time-series data set of high income countries demonstrates that happiness does not rise with the rise of income. To solve the paradox, this paper proposes that each data set reveals a different facet of happiness. The cross-sectional data set asks people how they assess their current well-being in general. This question prompts people to contrast their current well-being with a well-being in the distant past. This explains why happiness tracks income. In comparison, the time-series data ask people how they feel at the moment. This question prompts people to contrast their current well-being with an aspired goal in the future. Their response is a function of the gap that exists between their current well-being and the aspired one. The gap is usually steady for high income countries and, hence, happiness is likewise steady, i.e., insensitive to the rise of income. The proposed solution highlights the operation of contextual assessment: we have two facets of happiness following the two kinds of context in operation.Other Information Published in: International Review of Economics

description: How do landscape fragmentation affects ecosystems diversity and stability is an important and complex question in ecology with no simple answer, as spatially separated habitats where species live are highly dynamic rather than just static. Taking into account the species dispersal among nearby connected habitats (or patches) through a common dynamic environment, we model the consumer-resource interactions with ring type coupled network. Characterizing the dynamics of consumer-resource interactions in a coupled ecological system with three fundamental mechanisms: such as the interaction within the patch, the interaction between the patch and the interaction through a common dynamic environment, we report the occurrence of various atypical collective behaviors. We show that, the interplay between dynamic environment and dispersal among connected patches exhibits the mechanism of generation of oscillations, i.e., rhythmogenesis, as well as suppression of oscillations, i.e., amplitude death and oscillation death. Also, the transition of homogeneous steady state to inhomogeneous steady state occurs through a co-dimension-2 bifurcation. Emphasizing a network of spatially extended system, the coupled model exposes the collective behavior of synchrony-stability relationship with various synchronization occurrences such as in-phase and out-of-phase.

description: We investigate the efficiency of a quantum Carnot engine based on open quantum dynamics theory. The model includes time-dependent external fields for the subsystems controlling the isothermal and isentropic processes and for the system--bath (SB) interactions controlling the transition between these processes. Numerical simulations are conducted in a nonperturbative and non-Markovian SB coupling regime using the hierarchical equations of motion under these fields at different cycle frequencies. The work applied to the total system and the heat exchanged with the baths are rigorously evaluated. In addition, by regarding quasi-static work as free energy, we compute the quantum thermodynamic variables and analyze the simulation results using thermodynamic work diagrams for the first time. Analysis of these diagrams indicates that, in the strong SB coupling region, the fields for the SB interactions are major sources of work, while in other regions, the field for the subsystem is a source of work. We find that the maximum efficiency is achieved in the quasi-static case and is determined solely by the bath temperatures, regardless of the SB coupling strength, which is a numerical manifestation of Carnot's theorem.

description: This paper reports, the use of thiophene-based polymer P3HT as hole conducting agent to replace gel electrolyte in
ZnO based quasi-solid state dye-sensitized solar cell (DSSC). P3HT was used as hole conducting polymer for the solid state
DSSC of the structure ITO/ZnO/Rose-Bengal/P3HT/Pt (Cell A). A quasi-solid DSSC, ITO/ZnO/Rose-Bengal/Gel-Electrolyte/Pt,
(Cell B) was also fabricated using low molecular weight Poly Ethylene Glycol, (Mw 6000, PEG6000) as gel. The cell A delivered
an overall power conversion efficiency of ~2.59 % under 100 mW.cm-2 (air mass: 1.5). The cell B generated an overall power
conversion efficiency of ~ 5.56 % under similar conditions. Although in DSSCs based on gel electrolyte the efficiency is higher
but have problem associated with the sealing problems which limits device stability. The present work reveals that P3HT could act
as a good hole conducting agent for solid state DSSCs.

description: The recent CSP Rush in countries with high irradiation, such as in North Africa and the Middle East, has
often overshadowed the possibilities of PV implementation in the same region. The main arguments for this rush are the
relatively low energy generation costs and the economies of scale for 50 MW plants and above. Nevertheless, PV plants
in the range of 20 to 40 MW and beyond have become a standard in Spain, and no longer present technical barriers.
Furthermore, turn-key PV plants can be delivered today within a period of twelve months and are easily expendable.
Among others, this paper is aimed at utilities and independent energy producers in regions which are looking for
solutions and may have overlooked the PV alternative.
On the basis of feasibility studies recently carried out in Tunisia and the United Arab Emirates, this paper explores the
possibility of implementing large PV plants in these regions. This paper starts on a brief comparison of the technologies
main technical characteristics and market maturity. The PV technology covers the conventional crystalline technology,
as well as dual axis tracking systems and thin film modules. Following this technology introduction, this paper looks at
the energy yield of each and finishes on a consideration of the Energy Generation Costs today and in coming years.
The results show that the PV alternative does not lie much higher than CSP when it comes to the Energy Generation
Costs, without mentioning the other advantages that the technology brings.
