description: [Objectives] To study the effects of different temperature, time and humidity on the sensory quality of fish meat, and to determine the optimal process parameters for whole fish frying of Sichuan-style dry-roasted fish using a universal oven. [Methods] The effects of different heating temperature, time and humidity on the sensory quality of whole fish frying were analyzed by single factor experiment and orthogonal experiment. [Results] In the whole fish frying process of the universal oven, the optimal parameters in the first stage steaming mode was as follows: 215 °C for temperature, 15% for humidity, and 10 min for time; the optimal parameters in the second baking mode was as follows: 250 °C for temperature, 70% for humidity, and 5 min for time. [Conclusions] Different from the traditional whole fish frying of Sichuan-style dry roasted fish, universal oven is greatly optimized in convenience, safety and environmental protection. Besides, the use of oil is reduced, and the cost is well controlled, thus it is conducive to mass production in the later period.

description: The change of bulk excess charge carrier lifetime of silicon wafers along the processing stages of PERC solar cellsis investigated. As PERC solar cells efficiency improve currently very fast the material quality and its change during processing is becoming more and more important. We perform this work on Ga-doped Czochralski grown wafers which are not affected by boron-oxygen related light induced degradation. The bulk carrier lifetime reduces from an initial high level during the PERC process monitored after phosphorous diffusion and after the application of dielectric layers. However, after screen-printing and the following co-firing step the bulk carrier lifetime improves.A balanced temperature management during cell processing of temperature ramps, peak temperatures and times is necessary for high efficiency PERC cells which benefit more and more of high bulk carrier lifetime.

description: Recent nuclear magnetic resonance and specific heat measurements have provided concurring evidence of spontaneously broken rotational symmetry in the superconducting state of the doped topological insulator Cu$_x$Bi$_2$Se$_3$. This suggests that the pairing symmetry corresponds to a two-dimensional representation of the $D_{3d}$ crystal point group, and that Cu$_x$Bi$_2$Se$_3$ is a nematic superconductor. In this work, we present a comprehensive study of the upper critical field $H_{c2}$ of nematic superconductors within Ginzburg-Landau (GL) theory. Contrary to typical GL theories which have an emergent U(1) rotational symmetry obscuring the discrete symmetry of the crystal, the theory of two-component superconductors in trigonal crystals reflects the true $D_{3d}$ crystal symmetry. This has direct implications for the upper critical field. First, $H_{c2}$ of trigonal superconductors exhibits a sixfold anisotropy in the basal plane. Second, when the degeneracy of the two components is lifted by, e.g., uniaxial strain, $H_{c2}$ exhibits a twofold anisotropy with characteristic angle and temperature dependence. Our thorough study shows that measurement of the upper critical field is a direct method of detecting nematic superconductivity, which is directly applicable to recently-discovered trigonal superconductors Cu$_x$Bi$_2$Se$_3$, Sr$_x$Bi$_2$Se$_3$, Nb$_x$Bi$_2$Se$_3$, and Tl$_x$Bi$_2$Se$_3$.

description: In this paper, we introduce the concept of spatially coupled turbo-like codes (SC-TCs) as the spatial coupling of a number of turbo-like code ensembles. In particular, we consider the spatial coupling of Berrou et al. parallel concatenated codes (PCCs) and Benedetto et al. serially concatenated codes (SCCs). Furthermore, we propose two extensions of braided convolutional codes (BCCs), a class of turbo-like codes which have an inherent spatially coupled structure, to higher coupling memories, and show that these yield improved belief propagation (BP) thresholds as compared to the original BCC ensemble. We derive the exact density evolution (DE) equations for SC-TCs and analyze their asymptotic behavior on the binary erasure channel. We also consider the construction of families of rate-compatible SC-TC ensembles. Our numerical results show that threshold saturation of the belief propagation (BP) decoding threshold to the maximum a-posteriori threshold of the underlying uncoupled ensembles occurs for large enough coupling memory. The improvement of the BP threshold is especially significant for SCCs and BCCs, whose uncoupled ensembles suffer from a poor BP threshold. For a wide range of code rates, SC-TCs show close-to-capacity performance as the coupling memory increases. We further give a proof of threshold saturation for SC-TC ensembles with identical component encoders. In particular, we show that the DE of SC-TC ensembles with identical component encoders can be properly rewritten as a scalar recursion. This allows us to define potential functions and prove threshold saturation using the proof technique recently introduced by Yedla et al..

description: We developed crystalline Si solar cell fabrication process for both n- and p-bifacial PERT (Passivated Emitter and Rear Totally diffused) cell using non-mass separation type (NMS) ion implantation. At first, we fabricated n-bifacial selective emitter (SE) PERT solar cell and were able to control of Rsh of SE structure by controlling of conditions of ion implantation and activation annealing. Cell efficiency of n-bifacial PERT was obviously increased by introducing SE structure and the gain of  by SE structure was 0.4%abs. Combination of SE and other optimization of cell processes improved all IV parameters, and we achieved 21%. Furthermore, we fabricated p-bifacial PERT cell using same process for n-bifacial PERT, and difference of  was just 0.7%abs. Thus, we were able to confirm the applicability of our developed process to p-type cell. These results clearly show the effectiveness of our PERT cell process using NMS ion implanter and the feasibility of high efficiency low cost solar cell using our cell fabrication process.

description: High Performance multicrystalline silicon ingots are mostly produced with seeded growth on small size
silicon material, which determines the beneficial initial grain structure and orientations of the crystallites. A drawback
of this approach is the increased area of low minority charge carrier lifetime in the lower part of the ingot and thus a
worse yield. Also, the solidification process time is increased as the seed has to remain solid in a well controlled
manner. Both drawbacks can be addressed by using a thin seeding layer on the crucible bottom, which has a higher
melting point than silicon. The area of low minority carrier lifetime at the ingot bottom is comparable to standard
multicrystalline silicon, whereas the crystal structure is significantly improved. Several seeding layer configurations
were investigated and SiO2 with different grain sizes was chosen for G1-sized experiments. The resulting brick shows
a grain and defect structure close to the High Performance multicrystalline silicon reference while reducing the width
of the impurity indiffusion zone in the bottom. By optimizing the seeding layer in conjunction with the thermal
process, a higher yield of high quality material is possible.

description: In this work, the diamond wire wafering process for the production of crystalline silicon wafers is
considered. Using different control strategies, the aim is to optimize the wire sawing process regarding productivity
while maintaining an adequate wafer quality. The following approach has been chosen: assuming a given set of
production resources, a dynamic model of the wire sawing process is established that simulates the relevant process
variables. Then, reference values are defined for variables for which a reliable operation is expected. Using these
reference values as constraints, different control strategies are subjected to a model-based evaluation. Simulation results
indicate that a significant increase in productivity is possible using feed rate control in combination with alternative
strategies to distribute wire performance.

description: The spectra and wave functions of heavy-light mesons are calculated within a relativistic quark model, which is based on a heavy-quark expansion of the instantaneous Bethe-Salpeter equation by applying the Foldy-Wouthuysen transformation. The kernel we choose is the standard combination of linear scalar and Coulombic vector. The effective Hamiltonian for heavy-light quark-antiquark system is calculated up to order $1/m_Q^2$. Our results are in good agreement with available experimental data except for the anomalous $D_{s0}^*(2317)$ and $D_{s1}(2460)$ states. The newly observed heavy-light meson states can be accommodated successfully in the relativistic quark model with their assignments presented. The $D_{sJ}^*(2860)$ can be interpreted as the $|1^{3/2}D_1\rangle$ and $|1^{5/2}D_3\rangle$ states being members of the 1D family with $J^P=1^-$ and $3^-$.

description: Surface band bending evaluation by assessing Terahertz (THz) emission from silicon wafers using a laser
terahertz emission microscope (LTEM) is systematically and quantitatively compared with the non-contact voltagecharge
(V-Q) method which utilize a Kelvin probe. The amplitude of THz emission consistently changed with the
surface barrier voltage Vsb of non-contact V-Q when the surface was depleted or weakly inverted. The deposited charge
density required to zero THz amplitude was close to Qtot of noncontact C-V, the charge needed to move the surface
from initial condition to the flatband. When the surface had accumulation layer, the THz emission showed sensitivity
to the surface charging, while Vsb = 0 and was insensitive to the surface charging. The amplitude of THz emission
saturated when the surface was strongly inverted or accumulated. The results show that the LTEM can be a tool similar
to the non-contact V-Q in combination with a corona charging. Furthermore, the sensitivity of THz emission to the
both of depleted and accumulated surface suggests that the LTEM can be a tool to evaluate surface field of silicon
surfaces to which corona charging is not applicable.

Apo, 3000 ft, 06.59N, 125.16E (Dickinson et al., 1991: 415), Mindanao Island, Philippines, in October 1903, by Johannes Waterstradt. From the Rothschild Collection. COMMENTS: In the original description, Hartert designated the type as a male collected at 3000 ft on Mt. Apo in October 1903; however, three such specimens were collected by Waterstradt at that time. Hartert’s (1920a: 429) listing of the type did not further distinguish among these three specimens. Dickinson et al. (1991: 397), by giving AMNH 697926 by number as the holotype, effectively designated it the lectotype (ICZN, 1999: 82, Art. 74.5). The specimen bears a Rothschild type label in addition to Waterstradt’s field label and is, indeed, the specimen Hartert intended as the type. The two paralectotypes are: AMNH 697927 and AMNH 697928, males from Mt. Apo, 3000 ft, October 1903.

description: Atmospheric pressure chemical vapour deposition (APCVD) of phosphosilicate glass (PSG) layer allows a separation of glass deposition and phosphorous diffusion step. This permits the application of the selective laser-doping process either before or after the thermal diffusion, which increases the freedom of tailoring the doping profiles of both lowly and highly doped regions of selective emitter structures. We fabricate industrial p-type PERC solar cells featuring APCVD PSG-based selective emitters and study the effect of laser-doping process on current-voltage characteristics. Mean conversion efficiency mean = 21.1% and an absolute gain mean = 0.2% to the homogeneous emitters is achieved for solar cells after applying the laser-doping process either before or after the thermal drive-in. The most promising selective emitter group is the one featuring the laser process before the thermal diffusion step, where a carrier concentration profile with depth d = 0.9 μm as well as a low specific contact resistivity (C,mean ≈ 3 mΩ cm2) are achieved. The major electrical loss of this group is related to the spectral response, where a higher front-reflection and an increased recombination at the illuminated fraction of the highly doped region need to be minimized in order to further push the efficiency level to  > 21.5%.

description: This work focuses on the downlink and uplink of large-scale single-cell MU-MIMO systems in which the base station (BS) endowed with $M$ antennas communicates with $K$ single-antenna user equipments (UEs). Particularly, we aim at reducing the complexity of the linear precoder and receiver that maximize the minimum signal-to-interference-plus-noise ratio subject to a given power constraint. To this end, we consider the asymptotic regime in which $M$ and $K$ grow large with a given ratio. Tools from random matrix theory (RMT) are then used to compute, in closed form, accurate approximations for the parameters of the optimal precoder and receiver, when imperfect channel state information (modeled by the generic Gauss-Markov formulation form) is available at the BS. The asymptotic analysis allows us to derive the asymptotically optimal linear precoder and receiver that are characterized by a lower complexity (due to the dependence on the large scale components of the channel) and, possibly, by a better resilience to imperfect channel state information. However, the implementation of both is still challenging as it requires fast inversions of large matrices in every coherence period. To overcome this issue, we apply the truncated polynomial expansion (TPE) technique to the precoding and receiving vector of each UE and make use of RMT to determine the optimal weighting coefficients on a per-UE basis that asymptotically solve the max-min SINR problem. Numerical results are used to validate the asymptotic analysis in the finite system regime and to show that the proposed TPE transceivers efficiently mimic the optimal ones, while requiring much lower computational complexity.

Characterisation & Simulation Methods for Si Cells

description: 35th European Photovoltaic Solar Energy Conference and Exhibition; 273-277
description: In this paper, the use of transient thermal measurements inspired by the micro-electronic industry is demonstrated. The transient thermal measurement method entails applying pulsed power through a thermal test chip, with integrated heaters and temperature sensors, laminated on top of a polyolefin elastomer encapsulant layer and a silicon substrate, mimicking the PV module buildup. Measurements of the transient temperature response show that the thermal response variations in the thermally insulating encapsulant material are proportional to the thickness of the material. In addition, introducing direct metal contact the cell surface causes a higher thermal response than only embedding metal in the encapsulant without contact to the cell. Following preliminary transient temperature response measurements of the polyolefin encapsulant, we ran simulations to represent the impact of thermal properties of encapsulant on the overall impact of energy yields in PV modules. Simulation results show that altering encapsulant material from polyolefin to EVA, as well as varying polyolefin thickness within the PV module, have minor impact on the overall energy yields in moderate and desert climates.

Characterisation & Simulation Methods for Si Cells

description: 35th European Photovoltaic Solar Energy Conference and Exhibition; 281-286
description: In this study, we present a method to predict the local temperature dependent performance of silicon solar cells from wafer lifetime images which enables local investigation of silicon solar cell parameters under realistic operation conditions. The multicrystalline silicon wafers investigated underwent high temperature steps equivalent to emitter diffusion and contact firing for the production of a PERC solar cell. Injection and temperature dependent lifetime images, gathered by calibrated photoluminescence imaging, are combined with numerical cell device simulations using Quokka3. Hereby, the spatially resolved open-circuit voltage VOC, short-circuit current density jSC, fill factor FF and the efficiency  of a virtual solar cell based on the characterized material are predicted for various temperatures. This data is used to compute temperature coefficients of the aforementioned cell parameters. Our predictions are validated by a comparison with measurement results of cells made from sister wafers, which are analyzed globally and spatially resolved via PL imaging, Lock-in Thermography and Light-Beam-Induced-Current measurements.

description: We present a detailed study of local and non-local correlations in the electronic structure of elemental transition metals carried out by means of the Quasiparticle Self-consistent GW (QSGW ) and Dynamical Mean Field Theory (DMFT). Recent high resolution ARPES and Haas-van Alphen data of two typical transition metal systems (Fe and Ni) are used as case study. (i) We find that the properties of Fe are very well described by QSGW. Agreement with cyclotron and very clean ARPES measurements is excellent, provided that final-state scattering is taken into account. This establishes the exceptional reliability of QSGW also in metallic systems. (ii) Nonetheless QSGW alone is not able to provide an adequate description of the Ni ARPES data due to strong local spin fluctuations. We surmount this deficiency by combining nonlocal charge fluctuations in QSGW with local spin fluctuations in DMFT (QSGW + 'Magnetic DMFT'). (iii) Finally we show that the dynamics of the local fluctuations are actually not crucial. The addition of an external static field can lead to similarly good results if non-local correlations are included through QSGW.

description: We study analytically quantum tunneling of relativistic and non-relativistic particles at both Killing and universal horizons of Einstein-Maxwell-aether black holes, after high-order curvature corrections are taken into account, for which the dispersion relation of the particles becomes nonlinear. Our results at the Killing horizons confirm the previous ones, i.e., at high frequencies the corresponding radiation remains thermal and the nonlinearity of the dispersion does not alter the Hawking radiation significantly. In contrary, non-relativistic particles are created at universal horizons and are radiated out to infinity. The radiation also has a thermal spectrum, and the corresponding temperature takes the form, $T^{z}_{UH} = 2κ_{UH} (z-1)/(2πz)$, where $z$ denotes the power of the leading term in the nonlinear dispersion relation, $κ_{UH}$ is the surface gravity of the universal horizon, defined by peering behavior of ray trajectories at the universal horizon. We also study the Smarr formula by assuming that: (a) the entropy is proportional to the area of the universal horizon, and (b) the first law of black hole thermodynamics holds, whereby we derive the Smarr mass, which in general is different from the total mass obtained at infinity. This indicates that one or both of these assumptions must be modified.

description: This paper considers the growth rates of positive solutions of scalar nonlinear functional and Volterra differential equations. The equations are assumed to be autonomous (or asymptotically so), and the nonlinear dependence grows less rapidly than any linear function. We impose extra regularity properties on a function asymptotic to this nonlinear function, rather than on the nonlinearity itself. The main result of the paper demonstrates that the growth rate of the solution can be found by determining the rate of growth of a trivial functional differential equation (FDE) with the same nonlinearity and all its associated measure concentrated at zero; the trivial FDE is nothing other than an autonomous nonlinear ODE. We also supply direct asymptotic information about the solution of the FDE under additional conditions on the nonlinearity, and exploit the theory of regular variation to sharpen and extend the results.

description: A synergistic efficiency gain analysis (SEGA) determines the efficiency gain to be expected when idealizing a certain cell property. Moreover, it provides valuable information about synergistic effects due to the coupling of loss mechanisms, e.g. various recombination losses. Here we introduce an easy to use simulation tool to the PV community for performing a SEGA for PERC, PERC+, PERT, and IBC silicon solar cells. The simulation tool comes with a graphical user interface. This SEGA-GUI creates the required set of input files after entering all experimental parameters, e. g. the sheet resistance and recombination current of an emitter. The SEGA-GUI then performs the simulations by running Quokka 2 and analyzes the results. Programming knowledge is not required. The SEGA-GUI is designed to help the user in finding options for efficiency improvements. In this work we analyze our 22.1%-efficient PERC+ solar cell. The SEGA-GUI can be downloaded for free from the ISFH website.

description: We show that, under particular conditions, if a t-structure in the unbounded derived category of a locally coherent Grothendieck category restricts to the bounded derived category of its category of finitely presented objects, then its heart is itself a locally coherent Grothendieck category. Those particular conditions are always satisfied when the Grothendieck category is arbitrary and one considers the t-structure associated to a torsion pair in the category of finitely presented objects. They are also satisfied when one takes any compactly generated t-structure in the derived category of a commutative noetherian ring which restricts to the bounded derived category of finitely generated modules. As a consequence, any t-structure in this latter bounded derived category has a heart which is equivalent to the category of finitely presented objects of some locally coherent Grothendieck category.

description: The ZEBRA cell concept realizes low cost and large area interdigitated back contact (IBC) silicon solar cells. Furthermore, the concept allows a homogeneously distributed reverse bias breakdown at low voltages over the total cell area. Even without bypass diodes no severe hot spots will occur under partial shadings condition in a module. Hence, the homogeneity of the power dissipation is crucial for the reliability of the module under partial shading conditions. Root causes of non-uniform power generation under reverse condition must be understood and controlled. In this paper the macroscopic breakdown behavior and microscopic properties of the sample structure are compared by means of DLIT, reverse-bias EL and SEM/EBIC as well as ToF-SIMS. The microstructure and the local diffusion profiles of a IBC cell with non-uniform reverse breakdown have been analyzed separately in terms of correlation to the reverse breakdown. It is know that the local formation of high doping gradients at p+n+-junction leads to a low reverse breakdown voltage. Microscopic reverse-bias EL was used as a fast technique for identification of non-uniform p+n+-junction formation. On microscopic scales the structural roughness contributes to a spatially non-uniform generation of highly doped p+n+-junctions. However, on larger scales the breakdown behavior can be controlled through the dopant diffusion process. Our results show that this effect originates from different boron diffusion profiles which results in a variation of the boron sheet resistance on a cell.
Charles Spurgeon and Followership

Organisational behaviour

description: The paper examines the exemplary followership of Charles Spurgeon while pastoring at the Metropolitan Tabernacle. It may appear odd at first to ascribe followership attributes to such a high-profile leader, but Spurgeon's correspondence between himself and the deacons displayed courageous followership behaviors. Followership is a mutual reciprocation of communication, compensation, and collaboration that concurrently forms and re-forms between both parties, furthering the organization's primary cause. Over the last few years, the Christian industrial complex has seen the downfall of many of its most prolific figures. Given the pitfalls of power many leaders face, the need to study exemplary followership is critical. The paper's methodology is a bounded case study in the field of pragmatic qualitative research utilizing primary (autobiographies), secondary (biographies), and tertiary sources (followership theory). Additionally, Spurgeon's sermons underwent syntactic concordancing to determine what the Prince of Preachers thought and taught about leadership. The paper's underlying theme is that Christian leadership is paradoxically followership, and Spurgeon's life exemplified it.

description: Processes have been developed to integrate CIGS solar foils directly in plastic or composite based products. Using injection moulding and vacuum forming it turned out, that mechanical stress is applied to the solar foil, upon cooling. Using intermediate stress relief layers, such as polyolefin, this stress could be reduced considerably. The high temperatures needed in injection moulding have only a minimal effect on the performance of the solar cells. Making curved products is possible with the solar foils, leading to new markets for solar energy. Outdoor performance is attractive, but indoors, only applications that require little power have potential.

description: Incident light on solar modules is either lost in reflection or heat generation or generates desired
electricity. In this work, we introduce and extended evaluation of PV modules by means of simulation and
measurements and quantify optical reflection losses, heat sources and electricity values in PV modules with
different bill of materials based on the material stack level. We introduce our optical and electrical loss analysis
model which evaluates PV modules in spectral dependent optical and voltage dependent electrical analysis which
can be used for any defined spectrums in any location in the word. We show that almost 75% of the incoming
incident light turns into heat sources with different loss mechanism while 7% to 10% of incoming light can be
reflected out of the stack. We also show that modules with anti-reflection coating can benefit about 2-4%rel. extra
efficiency compared to the modules with similar glass and no AR properties. The reduced reflection in glass level
increases the efficiency as well as the heat sources of the module. The Module with UV+ polymer
(Polyvinylbutyral, PVB) shows a low UV (Ultraviolet) absorption in the polymer in UV range and decreases the
degradation effects such as discoloration. Furthermore, modules with PVB encapsulation materials show about
2.5% extra electricity generation in module level compared to the similar module with encapsulant without UV+
properties (ethylene vinyl acetate, EVA).

description: In this paper, we consider a high-dimensional quantile regression model where the sparsity structure may differ between two sub-populations. We develop $\ell_1$-penalized estimators of both regression coefficients and the threshold parameter. Our penalized estimators not only select covariates but also discriminate between a model with homogeneous sparsity and a model with a change point. As a result, it is not necessary to know or pretest whether the change point is present, or where it occurs. Our estimator of the change point achieves an oracle property in the sense that its asymptotic distribution is the same as if the unknown active sets of regression coefficients were known. Importantly, we establish this oracle property without a perfect covariate selection, thereby avoiding the need for the minimum level condition on the signals of active covariates. Dealing with high-dimensional quantile regression with an unknown change point calls for a new proof technique since the quantile loss function is non-smooth and furthermore the corresponding objective function is non-convex with respect to the change point. The technique developed in this paper is applicable to a general M-estimation framework with a change point, which may be of independent interest. The proposed methods are then illustrated via Monte Carlo experiments and an application to tipping in the dynamics of racial segregation.
