description: Cadmium telluride (CdTe) PV technology is growing rapidly, and at present represents the largest
contributor by far to the sector of non-silicon based photovoltaics. It is therefore of high scientific as well as political
relevance to investigate and carefully monitor the environmental performance of CdTe modules and PV systems, as
they may soon start to play a larger and larger role in the world renewable energy budget. In particular, this work
aims at assessing to which extent CdTe PV is expected to play a relevant role with respect to Cd use and emission
flows in the future, and whether its role may be considered beneficial or detrimental to the environment. The
prospective analysis is based on three alternative scenarios for Cd flows in the world and in the EU-27, and a
comparison is made between the relative importance of CdTe PV with respect to Cd market shares and Cd emissions.
Results clearly show that, while CdTe PV may come to account for as much as one third of the global Cd demand in
2050, in each of the considered scenarios its contribution in terms of atmospheric Cd emissions would still be
negligible, when compared to other existing sources. This is a remarkable result, and should put to rest concerns
regarding the relative magnitude of the possible contribution of this technology to cadmium-related environmental
pollution. On the contrary, the prospective beneficial effect of CdTe photovoltaics in terms of sequestration of Cd
from otherwise potentially harmful stockpiles and non-regulated flows is demonstrated.

description: PV modules were fabricated using structured glass and investigated for the effect on light transmission and
module temperature. Four different types of commercially available structured glass were investigated: grooves, pyramids,
inverted pyramids and a very light structured type with only 5% increased surface area, along with flat glass modules for
experimental control purposes. Measurements of light transmission were collected as a function of angle of incidence using
an AM 1.5 G pulsed solar simulator. Results show an increase in Isc of up to 3.2% for pyramid structures with normally
incident light, and the gain increases at higher angles of incidence. Wind tunnel testing was used to evaluate the effect of
structured glass on module temperature. It was found that the surface structure has a significant cooling effect, increasingly
pronounced at higher wind speed. In an outdoor environment, there were observed to be competing influences on module
temperature: at low wind speed and high irradiance the increased light transmission associated with structured glass serves to
increase module temperature, whereas at higher wind speeds, the increased convective module cooling serves to decrease the
module temperature. Both the decreased temperature and increased light transmission will serve to increase the power
output of the textured glass modules.

description: Possible transcendental nature of Euler's constant $γ$ has been the focus of study for sometime now. One possible approach is to consider $γ$ not in isolation, but as an element of the infinite family of generalised Euler-Briggs constants. In a recent work \cite{GSS}, it is shown that the infinite list of generalized Euler-Briggs constants can have at most one algebraic number. In this paper, we study the dimension of spaces generated by these generalized Euler-Briggs constants over number fields. More precisely, we obtain non-trivial lower bounds (see \thmref{pre} and \thmref{linear-ind}) on the dimension of these spaces and consequently establish the infinite dimensionality of the space spanned. Further, we study linear and algebraic independence of these constants over the field of all algebraic numbers.

description: The amount of deuterium locked up in polycyclic aromatic hydrocarbons (PAHs) has to date been an uncertain value. We present a near-infrared (NIR) spectroscopic survey of HII regions in the Milky Way, Large Magellanic Cloud (LMC), and Small Magellanic Cloud (SMC) obtained with AKARI, which aims to search for features indicative of deuterated PAHs (PAD or Dn-PAH) to better constrain the D/H ratio of PAHs. Fifty-three HII regions were observed in the NIR (2.5-5 μm), using the Infrared Camera (IRC) on board the AKARI satellite. Through comparison of the observed spectra with a theoretical model of deuterated PAH vibrational modes, the aromatic and (a)symmetric aliphatic C-D stretch modes were identified. We see emission features between 4.4-4.8 μm, which could be unambiguously attributed to deuterated PAHs in only six of the observed sources, all of which are located in the Milky Way. In all cases, the aromatic C-D stretching feature is weaker than the aliphatic C-D stretching feature, and, in the case of M17b, this feature is not observed at all. Based on the weak or absent PAD features in most of the observed spectra, it is suggested that the mechanism for PAH deuteration in the ISM is uncommon.

description: This thesis is a qualitative, thematic study grounded in a feminist research framework. It explores the meaning that student mothers give to their educational experiences and connectedness. The stories of 26 student mothers have been explored through 46 extended, unstructured interviews and time spent in their schooling environment. Their stories describe their experiences before pregnancy, during pregnancy and as a mother in education. The three dominant themes discussed by the student mothers are fear and loss, stigma and judgment and hope and aspiration. In this thesis it is recognized that the narratives of these student mothers, like all narratives, are framed in a broader set of social circumstances.

description: Screen printing is a low cost process that is used extensively in the Silicon solar cell industry. We will
show how mathematical modelling of the screen-printing process gives insights into the design of thick film paste
rheology, screens, and printing dynamics to enable printing of narrower contact lines thereby increasing the current
generated by a c-Si photovoltaic cell. We focus on three key aspects of the process, namely the transfer of paste
ahead of the squeegee, the screen peeling dynamics, and the origin of line broadening. As a result, we are able to
predict realistic screen profiles and paste weights throughout a print cycle, including the effects of a shear-thinning
paste rheology. We also demonstrate that increasing the peeling angle increases both the speed of the peeling front
and proportion of fluid transferred to the substrate. Finally, we show that seepage of paste underneath the screen is
the primary origin of line broadening.
Structured Compute-and-Forward with phase precoding scheme: Beyond integers

description: -In this work, we focus on the K--user Gaussian Symmetric Complex-valued Interference Channels (GS-CIC). The Compute-and-Forward (CoF) protocol in wireless networks have been employed for Gaussian Symmetric Real-valued Interference Channels (GS-RIC) to achieve approximately the capacity of such channels and making Interference Alignment (IA) by solving a system of linear equations at destinations. We aim to adapt this protocol to GS-CIC. At high Signal-to-Noise Ratio (SNR), this protocol shows a fading behavior of the achievable sum-rate for strong and very strong interference regimes. In complex field this random-like behavior is related to the phase of complex cross channel coefficients. To avoid this fading-like behavior, we consider Z[i]--lattice codes and we propose a phase precoding scheme for CoF protocol with partial feedback. In this method the phase of channel coefficients will then be fed back to the transmitters in order to choose the best precoder factors to control this random behavior. We further simulate the achievable sum-rate given by this scheme and showing significant gain improvement can be obtained in terms of limiting the random behavior of achievable sum-rate.

description: Tilt angles show decisive impact on fixed tilted PV power plant design. A comprehensive irradiation and cost
optimizing model is presented based on Hay-Davis-Klucher-Reindl (HDKR) approach coupled with levelized cost of
electricity (LCOE). Results of the analysis are shown for all regions in the world. Trade-off between irradiation and
cost optimization is found. Rule of thumb, that tilt angle should be respective latitude can be confirmed for most
regions in the world, except those higher than 45°N or lower 45°S or of very special local climatic conditions.
Nevertheless, overall impact of tilt angle on maximizing irradiation should not be overestimated
A closure for Lagrangian velocity gradient evolution in turbulence using recent deformation mapping of initially Gaussian fields

Year: 2016
Subjects: subject: Fluid Dynamics (physics.flu-dyn)

description: The statistics of the velocity gradient tensor in turbulent flows are of both theoretical and practical importance. The Lagrangian view provides a privileged perspective for studying the dynamics of turbulence in general, and of the velocity gradient tensor in particular. Stochastic models for the Lagrangian evolution of velocity gradients in isotropic turbulence, with closure models for the pressure Hesssian and viscous Laplacian, have been shown to reproduce important features such as non-Gaussian probability distributions, skewness and vorticity strain-rate alignments. The Recent Fluid Deformation (RFD) closure introduced the idea of mapping an isotropic Lagrangian pressure Hessian as upstream initial condition using the fluid deformation tensor. Recent work on a Gaussian fields closure, however, has shown that even Gaussian isotropic velocity fields contain significant anisotropy for the conditional pressure Hessian tensor due to the inherent velocity-pressure couplings, and that assuming an isotropic pressure Hessian as upstream condition may not be realistic. In this paper, Gaussian isotropic field statistics are used to generate more physical upstream conditions for the recent fluid deformation mapping. In this new framework, known isotropy relations can be satisfied {\it a priori} and no DNS-tuned coefficients are necessary. A detailed comparison of results from the new model, referred to as the recent deformation of Gaussian fields (RDGF) closure, with existing models and DNS shows the improvements gained, especially in various single-time statistics of the velocity gradient tensor at moderate Reynolds numbers. Application to arbitrarily high Reynolds numbers remains an open challenge for this type of model, however.

description: The electricity industry is collecting large volumes of data from various sources. From regional grid demand to individual sensor readings in buildings, there is a wide range of disaggregated data sources requiring new techniques for forecasting and inference. A better understanding of how electricity is being used by consumers has the potential to increase energy efficiency and improve grid planning and management. This thesis presents several novel approaches to understanding these varied data sources. Contributions include advances in hierarchical probabilistic load forecasting; inference and forecasting using smart meter data and building characteristics; and exploratory analysis of building management system data.

description: Despite the advantages of solar PV over conventional power generation and its continuously growing part in
our energy mix, large scale PV developments are neither predictable, nor available like a thermal generation source. The
variability of PV is also limiting the insertion on the electrical grid, due to the need of important spinning reserve.
Distribution System Operators (DSO), the operators of the electrical grid, have to progress in understanding the way to better
insert this resource that can neither be predicted nor managed in a way to contribute to the grid stability. Integration issues
result namely from short term power variations due to cloud cover and other sources, and are particularly stringent on noninterconnected
island grids with high penetration of renewable energies. By associating large solar plants with high
performance Li-ion grid scale storage solutions, solar PV energy can be integrated to the grid like other regulated generation
assets. In this combination with adequate power conversion and power management systems, utility PV power can deliver
energy within a controlled profile and provide services such as frequency regulation or support to the grid during Low
Voltage Ride Through. The design of such a system requires a good understanding of a grid operator’s constraints and of the
variability of the PV generation due to the change of climate, it needs simulation of a dynamic battery – PV operation
profile, and design of the energy storage, conversion and management system in view of a reliable 20 years operation.

description: Indium sulfide layers were grown by an ultrasonic spray pyrolysis method for application in Cu(In,Ga)Se2 solar cells. For quantitative chemical composition measurements In2S3 layers were sprayed on silicon substrates and analyzed with Rutherford backscattering spectroscopy and elastic recoil detection analysis. A chemical treatment of the as-deposited In2S3 buffer on Cu(In,Ga)Se2 in a water, cadmium acetate, thiourea, and ammonia solution was found to improve the performance of the solar cells. This improvement is more pronounced for cells with initially low efficiency. Two different effects are observed after chemical treatment: (i) an increase of the Voc and FF for middle efficiency cells and (ii) a major increase in the Jsc for low efficiency cells.

manufacture by cheap and widely available machining techniques. All the considered configurations were compared
and quantitatively evaluated using lighting simulation software (Lambda Research Trace-Pro), considering the
collected power of obtained sunlight distributions.

description: Epitaxial boron-doped emitters by CVD can provide a valuable alternative to the use of aluminum or diffused
boron for the creation of p-type emitters. Compared to the traditional boron-diffusion emitters for high-efficiency cells,
epitaxial emitters need shorter process time, no boron skin removal step and have more opportunities to optimize the emitter
doping profile. Our work proves that epitaxial emitters can be a good alternative for p-type emitter. Very promising cell
results with the highest cell efficiency of 16.8 % under 1 Sun have been achieved. Good fill factors have been obtained
which indicate good metal contacts are obtained on the epitaxial emitter. Cell results of first tests on FZ n-type material are
very encouraging and indicate a high potential of such epitaxial emitters for rear junction n-type solar cells.

etching solutions exhibit a high reactivity towards multicrystalline silicon surfaces. For high sulfuric acid
concentrations nitronium ions were identified by means of Raman- and 14N-NMR-spectroscopic measurements.
Raman-spectroscopic investigations open a simple way for quantitative nitronium ion analysis. Etched surface

description: We determine a $q\to 1$ limit of the two-dimensional $q$-Whittaker driven particle system on the torus studied previously in [Corwin-Toninelli, arXiv:1509.01605]. This has an interpretation as a $(2+1)$-dimensional stochastic interface growth model, that is believed to belong to the so-called anisotropic Kardar-Parisi-Zhang (KPZ) class. This limit falls into a general class of two-dimensional systems of driven linear SDEs which have stationary measures on gradients. Taking the number of particles to infinity we demonstrate Gaussian free field type fluctuations for the stationary measure. Considering the temporal evolution of the stationary measure, we determine that along characteristics, correlations are asymptotically given by those of the $(2+1)$-dimensional additive stochastic heat equation. This confirms (for this model) the prediction that the non-linearity for the anisotropic KPZ equation in $(2+1)$-dimension is irrelevant.

description: Existing color sampling based alpha matting methods use the compositing equation to estimate alpha at a pixel from pairs of foreground (F) and background (B) samples. The quality of the matte depends on the selected (F,B) pairs. In this paper, the matting problem is reinterpreted as a sparse coding of pixel features, wherein the sum of the codes gives the estimate of the alpha matte from a set of unpaired F and B samples. A non-parametric probabilistic segmentation provides a certainty measure on the pixel belonging to foreground or background, based on which a dictionary is formed for use in sparse coding. By removing the restriction to conform to (F,B) pairs, this method allows for better alpha estimation from multiple F and B samples. The same framework is extended to videos, where the requirement of temporal coherence is handled effectively. Here, the dictionary is formed by samples from multiple frames. A multi-frame graph model, as opposed to a single image as for image matting, is proposed that can be solved efficiently in closed form. Quantitative and qualitative evaluations on a benchmark dataset are provided to show that the proposed method outperforms current state-of-the-art in image and video matting.

description: Intricate biomineralization processes in molluscs engineer hierarchical structures with meso-, nano-, and atomic architectures that give the final composite material exceptional mechanical strength and optical iridescence on the macroscale. This multiscale biological assembly inspires new synthetic routes to complex materials. Our investigation of the prism-nacre interface reveals nanoscale details governing the onset of nacre formation using high-resolution scanning transmission electron microscopy. A wedge polishing technique provides unprecedented, large-area specimens required to span the entire interface. Within this region, we find a transition from nanofibrillar aggregation to irregular early-nacre layers, to well-ordered mature nacre suggesting the assembly process is driven by aggregation of nanoparticles (~50-80 nm) within an organic matrix that arrange in fiber-like polycrystalline configurations. The particle number increases successively and, when critical packing is reached, they merge into early-nacre platelets. These results give new insights into nacre formation and particle-accretion mechanisms that may be common to many calcareous biominerals.

description: Measuring brain activity with electroencephalography (EEG) is mature enough to assess mental states. Combined with existing methods, such tool can be used to strengthen the understanding of user experience. We contribute a set of methods to estimate continuously the user's mental workload, attention and recognition of interaction errors during different interaction tasks. We validate these measures on a controlled virtual environment and show how they can be used to compare different interaction techniques or devices, by comparing here a keyboard and a touch-based interface. Thanks to such a framework, EEG becomes a promising method to improve the overall usability of complex computer systems.

description: Direct liquid immersion cooling of concentrator solar cells is proposed as a solution for the
temperature problem faced by concentrating photovoltaic (CPV) and hybrid concentrating photovoltaic thermal
(CPV-T) systems. Improvements to the electrical characteristics of ANU concentrator solar cells operated in
candidate dielectric liquids have been observed. These improvements arise from improved light collection and
reduced cell surface recombination losses from surface adsorption of polar molecules. Three-dimensional numerical
simulations have been performed to explore the thermal performance of a concentrator solar array in the novel
prototype receiver with de-ionised (DI) water, isopropyl alcohol (IPA), ethyl acetate and dimethyl silicon oil as the
working fluids. The simulation results show that low and uniform cell temperature can be maintained in the novel
receiver incorporating candidate liquids for direct immersion cooling with dummy cells to construct the leading
section of the solar cell array. The fluid inlet velocity and flow characteristics, and the inlet fluid temperature and
thermal properties have a decisive influence on the concentrator solar cell temperature.

Agricultural economics

description: This thesis looks at agricultural decision-making in changing environments. The environments in which smallholder producers in Southeast Asia operate in is changing rapidly. Increased incomes in the region have changed consumer demand, which provides opportunities in new markets for agricultural households. Producers also face several new challenges associated with climate change. Understanding agricultural decision-making is more important than ever, as the producers’ environments are changing faster than ever. In this thesis, we will look at agricultural decisions as they relate to climate change adaptation and mitigation, as well as why some producers enter new export markets while others do not.

description: In this paper we present our first results regarding the development of a Concentrating Photovoltaic
(CPV) systems based on a classical Cassegrain optical design and a beam homogenizer. The system is characterized
by a geometrical concentration factor (Cgeo) of around 500X. The optical design has been developed in order to
obtain a 10 mm wide square image. Particular attention has been devoted to the homogenizer and to its building
materials in order to reduce the cost and the thermal effects caused by concentrated radiation. Moreover the optical
design has been specifically chosen to produce a Sun square image that optimizes the pv cell coupling. The field of
view (FOV) of the designed concentrator is of +/- 0.5 degrees. The primary mirror has a 220 mm wide square
aperture and a focal length of 80 mm (f/0.4). The secondary mirror is hyperbolic with a magnification of 6X that lead
to a 4 mm diameter Sun image. In order to obtain a 10 mm wide square image, we used a total internal reflection
(TIR) homogenizer. In this way the focal plane may host a typical commercial triple junction PV receiver assembly
with a 10 mm squared active area. Cells of different sizes may be easily fitted by changing the exit side dimension of
the homogenizer. The optical design has been optimized and it is ready for the test and optical characterization.

description: At module level (one single solar cell), the Fresnel-Köhler (FK) concentrator comprises a perfect
irradiance uniformity along with quite high concentration-acceptance angle product and loose manufacturing
tolerances. At the same time, it maintains the efficiency/simplicity of other Fresnel-based concentrators. All these
facts, along with the pill-box shape of its transmission curve, permit an enhanced performance of this device,
compared to its competitors, at array level, because the system is less sensitive to manufacturing errors and cells
dispersion, and current mismatch is less likely to occur. Or the same performance can be achieved at a lower cost,
exhausting the tolerance budget by using inexpensive fabrication techniques. Depending on the concentrator, the
actual power delivered by an array might drop significantly with respect to the sum of the power delivered by single
modules. Under certain circumstances, the FK can reach a 1-10% electrical efficiency increase with regards to other
concentrators sharing the same technology.
International Trade and African Economic Development

description: This thesis first uses international trade data to estimate GDP for 17 African countries from the early 1800s to 1950. It then explores the effect of international trade on the labour markets and structural change in African economies and finds that trade may have the unanticipated impact of causing the wrong kind of structural change and labour market composition in Africa. It is, therefore, crucial to ensure that African countries are first put in a position to benefit from good policies like international trade before embarking on them.

description: This paper analyses the suitability of V. Ruiz model for both, daily global solar irradiation and
sunshine duration, to obtain TMY for the island of Gran Canaria. There are daily data available from seven
measurement stations all around the Island between 1998 and 2008. The relevant climatic parameters evolution can
be represented generating characteristic one year duration series provided by the TMY. This paper achieved the daily
typical TMY of maximums, means, medians, variance and percentiles of 90% and 75% series of values. In order to
improve the knowledge of solar intensities, it was obtained one TMY for each of those series using weight means to
smooth the irregular data, by means of Henderson’s model. Finally, the TMY series were fitted to third grade Fourier
series obtaining excellent results in all the locations around the Island. The irradiation daily data distribution is
asymmetric, generally concentrated in the right side (high irradiation values are more frequent than low ones) so, in
this paper, the real trend of the global irradiation behaviour in every location is represented by the Median TMY
series. The numerical TMY series allow evaluating the possibilities of solar power generation in the measurement
stations in Gran Canaria.

description: Presently there is no satisfactory technical solution available for the limitation of reverse currents
during installation and operation of a PV plant. The application of string fuse is very expensive and may cause new
safety problems. The favoured design of fuse-less PV plants will become possible with technical realization of a
device, which covers the requirements derived from the system analysis. An electronic PV fuse is introduced to avoid
reverse currents in a PV array. This approach improves the safety of PV plants by reducing total system costs (TCO:
total costs of ownership).

description: In industrial production of mono crystalline solar cells alkaline texturing is nowadays a standard
process. The most used process in industry is the KOH (or NaOH) / IPA process. In due to the small process
window is for most wafer qualities a different recipe needed. Here a new innovative alkaline texturing process for
cz silicon wafers is presented. The texturing solutions contains a new additive, named AlkaTex Plus. With this new
process most wafer qualities from different suppliers could be textured with the same recipe. In comparison to the
standard process the chemical consumption sinks. With a process time of 20 to 30 min the output could be
increased. With this new ESH compliant additive a typical pyramid size of 2 – 5 μm could be achieved.

description: This study develops a pointing-error model to improve the tracking accuracy of the concentrating
photovoltaics (CPV) module for the azimuth-elevation solar tracker. We develop a methodology to reduce the
apparent angles of the azimuth and elevation with coordinate transformation which describe the azimuth-elevation
system. The apparent angles of the azimuth and elevation in the new coordinate system have smaller displacement
which will facilitate the manipulation of the small-angle approximation in the pointing-error model. Based on
simulations, the average errors of combined offset-angle using the new model greatly reduced from 168.7% to 2.6%
during the summer session. Outdoor tests of the tracker with CPV modules installed also shown significant
enhancement in tracking accuracy (average angle reduce from 0.41o to 0.07o).
