Silicon Solar Cell Improvements

description: Manufacturers are seeking various approaches to achieve the lowest $/Watt possible. Reports show
that ion implantation is a powerful enabling technology for high efficiency c-Si solar cells, especially for advanced
cell structures. Ion implantation followed by anneal and activation provides superior p-n junction quality. It also has
accurate and precise process control. In addition, ion implantation technology simplifies the manufacturing process
by eliminating the PSG/BSG removal and edge isolation steps that are required for a diffusion process. Higher
efficiency together with a simplified process makes ion implantation technology a true lowest $/Watt enabler. This
paper presents the successful implementation of Solion ion implantation technology in mass production at
Astronergy, including cell conversion efficiency, light induced degradation, module power and reliability data.
NOVATM cells developed at Astronergy are p-type blanket emitter cells using Solion blue process provided by Varian
Semiconductor Equipment, a subsidiary of Applied Materials. The average cell conversion efficiency has reached
19.5% on average on 156mm x 156mm p-type mono-crystal silicon substrates in mass production. Modules made
with NOVATM cells have over 265W of peak power. In addition, all modules exhibit excellent PID performance.

Silicon Solar Cell Characterization and Modelling

description: 27th European Photovoltaic Solar Energy Conference and Exhibition; 735-739
description: We have developed a method to qualify multi-crystalline silicon (mc-Si) wafers that are being used in a
production process. An optical image of an etched wafer is made. This etching can be a standard industrial acid
etching for mc-Si wafers as is commonly used for saw damage removal and simultaneous iso-texturing. Digital
image processing is then applied to identify the number of dislocations and their distribution over the wafer. This
information is used as input for a cell performance prediction model, where the performance is characterized by the
open circuit voltage (Voc) or the efficiency. The model can include various levels of sophistication, i.e. from using an
average density of dislocations to the full spatial resolution of the dislocations in a 2D simulation that includes also
the metallization pattern on the cell. The predicted performance is then evaluated against pre-selected criteria. The
possibility to apply this optical qualification method in an initial stage in the production enables early rejection of the
wafers, further tailoring of the cell production process or identification of instabilities in the production process.

description: To understand spacetime dynamics in the canonical tensor model of quantum gravity for the positive cosmological constant case, we analytically and numerically study the phase profile of its exact wave function in a coordinate representation, instead of the momentum representation analyzed so far. A saddle point analysis shows that Lie group symmetric spacetimes are strongly favored due to abundance of continuously existing saddle points, giving an emergent fluid picture. The phase profile suggests that spatial sizes grow in "time", where sizes are measured by the tensor-geometry correspondence previously introduced using tensor rank decomposition. Monte Carlo simulations are also performed for a few small $N$ cases by applying a re-weighting procedure to an oscillatory integral which expresses the wave function. The results agree well with the saddle point analysis, but the phase profile is subject to disturbances in a large spacetime region, suggesting existence of light modes there and motivating future computations of primordial fluctuations from the perspective of canonical tensor model.

description: Selective emitter (SE) technology has been proved to be a promising high efficiency cell technology nowadays.
In this paper, we present a new and simplified solution to SE structure via Etch Back technique(EB) [1, 2]. We use one
diffusion step to form Heavily Doped Area (HDA) and then, an emitter etch back to form the Lightly Doped Area (LDA)
without any mask to cover HDA. In ECV test, a rather lower surface concentration was detected in LDA comparing with
HDA which is corresponding to the SE structure. After metallization, the highest absolute gain of cell efficiency was up
to 0.6%~0.7% on 6 inches mono CZ-wafers in the batch experiment and this absolute efficiency gain also was better than
original SE techniques. In IQE tests, better short wavelength response was also detected comparing with homogenous
emitter and original SE structure.

description: This work focused on industrial approaches of selective emitter formation using a screen printable
phosphorous paste on multi-crystalline silicon solar cells. In only one diffusion step, deeply diffused regions under
the printed doping source are formed and in the adjacent regions doping atoms diffuse from the printed source via
the gas atmosphere. A novel thermal diffusion process for a single diffusion selective emitter has been applied.
Solar cells with selective emitters have been fabricated and yield a gain of 0.3 %( abs.) Compared to the reference,
an average efficiency of 17.3 % was obtained in pilot line and the best efficiency is up to 17.7%.

description: The Swift X-ray Telescope focal plane camera is a front-illuminated MOS CCD, providing a spectral response kernel of 135 eV FWHM at 5.9 keV as measured before launch. We describe the CCD calibration program based on celestial and on-board calibration sources, relevant in-flight experiences, and developments in the CCD response model. We illustrate how the revised response model describes the calibration sources well. Comparison of observed spectra with models folded through the instrument response produces negative residuals around and below the Oxygen edge. We discuss several possible causes for such residuals. Traps created by proton damage on the CCD increase the charge transfer inefficiency (CTI) over time. We describe the evolution of the CTI since the launch and its effect on the CCD spectral resolution and the gain.

description: The performance of amorphous silicon is not stable because of the light-soaking and annealing
effects. Therefore a stable pseudo-reference solar cell (in WPVS or JIS package) with a similar relative spectral
response to the amorphous silicon or multi-junction cell is generally used for performance (Pmax) measurements.
Its structure is composed of a stable crystalline silicon cell and an optical filter. However this structure is the
reason for different optical characteristics from the actual tested sample and hence measurement errors are
introduced. One of the errors is caused by multiple-reflections between the photovoltaic (PV) device and the
output lens of a solar simulator. The effect may become significant under a short-distance type solar simulator
used for solar cell evaluation. The difference of the multiple-reflection level between reference cell and tested
sample directly introduces systematic errors on the Pmax measurement. The magnitude of the multiple-reflections
can be determined by measuring the incident light angle characteristics. Therefore a correction for those multiplereflections
can be applied based on measurements of the incident light angle characteristics. A correction method
will be proposed and the verification results for the correction will be reported in this paper.

description: The p-adic numbers have found applications in a wide range of diverse fields of research. In some applications the algebraic properties of p-adics enter as an indispensable ingredient of the theory. Another class of applications has to do with hierarchical tree like systems. In this context the applications are based on the well known correspondence between p-adics and the trees with p-branches emerging from every branching point. Then the algebraic structure does not enter and p-adics are used merely as a labeling system for the tree branches. We introduce a space of numerical sequences suitable for labeling the trees with varying number of branches emerging from the branching points. We equipe this space with a non Archimedian metric and describe its basic topological properties. We also demonstrate that the known construction of the stochastic processes on p-adics carry over to the stochastic processes on the above mentioned space and hence on the corresponding trees.

located in the same area, are subject to the same ambient temperature and radiation, and applied the same construction
criteria: PV panels, panel support system and wiring. Their main difference is found in the inverter technology that each
one uses: the inverter with the integrated transformer system is used in one facility and a transformerless inverter in the
other one. The results, in economic terms, highlight the importance of properly selecting the system components for
maximum profitability.

description: We present a study of sediment transport in the creeping and saltation regime. In our model, a bed of particles is simulated with the conventional event-driven method. The particles are considered as hard disks in a 2d domain, with periodic boundary conditions in horizontal direction. The flow of the fluid over this bed of particles is modeled by imposing a force on each particle that depends on the velocity of the fluid and its height above the bed. We considered two velocity profiles for the fluid, parabolic and logarithmic. The first one models laminar flow and the second corresponds to turbulent flow. For each case we investigated the behavior of the saturated flux. We found that for the logarithmic profile, the saturated flux shows a quadratic increase with the strength of the flow, and for parabolic profile, a cubic increase. The velocity distribution functions are used to interpret the results.

description: A Building Integrated façade PV system is studied and the performance of a 8 months period of
operation is reported. An alternative method based on satellite data for reference values of insolation is described
together with an analysis of the reliability and the downsides of the method. The plant presents the interesting
characteristics of being composed by two façades at a 90° degrees angle facing SE and SW direction.
The performance analysis requires a translation of the Global Horizontal Irradiation (GHI) data computed from the
Meteosat Second Generation satellite to Global Tilted Irradiance (GTI) data at 90° degrees and at two different
azimuthal angles. The reliability of the method is discussed comparing provided GHI data with values measured by a
pyranometer. The energy production from modules at different orientation is analysed and the results are critically
compared with other PV plants configurations for a better understanding of BIPV façade systems.
An intermittency parameter is also provided which could prove useful for planning of BIPV systems and to compare
performance of plants based on different renewable energy sources.

description: The occurrence of thermally induced stresses during the crystallization process for mc-Si in PV is widely known and
was object of various simulation studies. It is also widely known that, at high temperatures, stresses can be partially
released by plastic deformation during crystallization and cool down processes. After complete cool down residual
stresses remain in the material and can lead to material breakage during further process steps (sawing, wafer
handling, cell process). Although the models predicting stress, strain and dislocation multiplication are well
developed there is yet a lack in measurement techniques for residual stresses, especially in voluminous samples like
mc-Si ingots, bricks and columns.
Based on the relevant literature we checked the applicability of different techniques of stress measurements
established in material science to the conditions given by voluminous Si samples. We tested typical non-destructive
methods like infrared birefringence and ultrasound velocity measurements. For our own experiments we tested two
destructive techniques, the hole-drilling method and the dissection method on mc-Si samples in the shape of central
boards or side boards of G4 and G1 ingots.
It turned out that, as predicted by simulations, the stresses are in the range of about 5 MPa in G4-sized samples and
less than 1 MPa in G1-sized, too small to be detected accurately by most of the investigated measurement techniques.
At the end, the infrared birefringence method and the dissection method are most promising candidates for practical
techniques to determine stress states as they are present in large ingots.

description: By way of the projected phase-space (PPS), we investigate the relation between galaxy properties and cluster environment in a subsample of groups from the Yang Catalog. The sample is split according to the gaussianity of the velocity distribution in the group into gaussian (G) and non-gaussian (NG). Our sample is limited to massive clusters with $\rm M_{200} \geq 10^{14} M_{\odot}$ and $\rm 0.03\leq z \leq 0.1$. NG clusters are more massive, less concentrated and have an excess of faint galaxies compared to G clusters. NG clusters show mixed distributions of galaxy properties in the PPS compared to the G case. Using the relation between infall time and locus on the PPS, we find that, on average, NG clusters accreted $\rm \sim 10^{11}\,M_{\odot}$ more stellar mass in the last $\sim 5$ Gyr than G clusters. The relation between galaxy properties and infall time is significantly different for galaxies in G and NG systems. The more mixed distribution in the PPS of NG clusters translates into shallower relations with infall time. Faint galaxies whose first crossing of the cluster virial radius happened 2-4 Gyr ago in NG clusters are older and more metal-rich than in G systems. All these results suggest that NG clusters experience a higher accretion of pre-processed galaxies, which characterizes G and NG clusters as different environments to study galaxy evolution.

description: To account for privacy perceptions and preferences in user models and develop personalized privacy systems, we need to understand how users make privacy decisions in various contexts. Existing studies of privacy perceptions and behavior focus on overall tendencies toward privacy, but few have examined the context-specific factors in privacy decision making. We conducted a survey on Mechanical Turk (N=401) based on the theory of planned behavior (TPB) to measure the way users' perceptions of privacy factors and intent to disclose information are affected by three situational factors embodied hypothetical scenarios: information type, recipients' role, and trust source. Results showed a positive relationship between subjective norms and perceived behavioral control, and between each of these and situational privacy attitude; all three constructs are significantly positively associated with intent to disclose. These findings also suggest that, situational factors predict participants' privacy decisions through their influence on the TPB constructs.

description: Galactic charged cosmic rays (notably electrons, positrons, antiprotons and light antinuclei) are powerful probes of dark matter annihilation or decay, in particular for candidates heavier than a few MeV or tiny evaporating primordial black holes. Recent measurements by PAMELA, AMS-02, or VOYAGER on positrons and antiprotons already translate into constraints on several models over a large mass range. However, these constraints depend on Galactic transport models, in particular the diffusive halo size, subject to theoretical and statistical uncertainties. We update the so-called MIN-MED-MAX benchmark transport parameters that yield generic minimal, median and maximal dark-matter induced fluxes; this reduces the uncertainties on fluxes by a factor of about 2 for positrons and 6 for antiprotons, with respect to their former version. We also provide handy fitting formulae for the associated predicted secondary antiproton and positron background fluxes. Finally, for more refined analyses, we provide the full details of the model parameters and covariance matrices of uncertainties.

description: We present a method for fast optimal estimation of the temperature angular power spectrum from observations of the cosmic microwave background. We employ a Hamiltonian Monte Carlo (HMC) sampler to obtain samples from the posterior probability distribution of all the power spectrum coefficients given a set of observations. We compare the properties of the HMC and the related Gibbs sampling approach on low-resolution simulations and find that the HMC method performs favourably even in the regime of relatively low signal-to-noise. We also demonstrate the method on high-resolution data by applying it to simulated WMAP data. Analysis of a WMAP-sized data set is possible in a around eighty hours on a high-end desktop computer. HMC imposes few conditions on the distribution to be sampled and provides us with an extremely flexible approach upon which to build.

description: In this paper, we have investigated the effect of partial shading due to moving clouds on mismatch losses of five different PV power generator configurations. These configurations are a string of six series-connected PV modules, two strings of three series-connected PV modules, which are either separately controlled or connected in parallel, and three strings of two series-connected PV modules, which are also either separately controlled or connected in parallel. The work has been conducted by using Matlab Simulink simulation models of the PV power generators with actual measured irradiance and temperature data as an input for the models. The results show that the mismatch losses due to partial shading caused by clouds increase with increasing length of the series connections. In order to minimize these mismatch losses, the length of the strings should be kept as short as possible.

In contrast to standard wave barriers, we study the case where the dielectric permittivity is positive, and the barrier is caused by the inhomogeneous dielectric profile. It is found that reflectionless, superluminal tunneling can take place for waves with a finite spectral width. The consequences of these findings are discussed, and an experimental setup testing our predictions is proposed.

description: The surface quality of silicon wafers cut by multi-wire saw must be controlled in order to reduce the
breakage risk during the process as well as to improve the final solar cell efficiency. In addition, investigating the
wafer surface can also provide useful information for improving the wire-sawing process. In this paper, the
experience with running wafer inspection lines and a wire sawing test lab will be described. The objective is to
demonstrate the correlation of the wafer surface defects with the wire saw parameters, as well as to stimulate
discussion on the use of wafer inspection systems for wire-saw process improvements. A database with more than
200 different cutting conditions was investigated. Certain types of surface defects in this investigation were found to
be strongly related to the cut parameters variations during the cut. Building up a centralized system to monitor several
wire saw machine parameters and the corresponding wafer inspection data contributed to manage the operating status
of the machines as well as to improve the cutting process, which can eventually lead to cutting yield improvements
and wafering cost reductions.

description: We propose a monocular depth estimator SC-Depth, which requires only unlabelled videos for training and enables the scale-consistent prediction at inference time. Our contributions include: (i) we propose a geometry consistency loss, which penalizes the inconsistency of predicted depths between adjacent views; (ii) we propose a self-discovered mask to automatically localize moving objects that violate the underlying static scene assumption and cause noisy signals during training; (iii) we demonstrate the efficacy of each component with a detailed ablation study and show high-quality depth estimation results in both KITTI and NYUv2 datasets. Moreover, thanks to the capability of scale-consistent prediction, we show that our monocular-trained deep networks are readily integrated into the ORB-SLAM2 system for more robust and accurate tracking. The proposed hybrid Pseudo-RGBD SLAM shows compelling results in KITTI, and it generalizes well to the KAIST dataset without additional training. Finally, we provide several demos for qualitative evaluation.

description: We consider the rank-reduced coupled-cluster theory with single and double excitations (RR-CCSD) introduced recently [Parrish \emph{et al.}, J. Chem. Phys. {\bf 150}, 164118 (2019)]. The main feature of this method is the decomposed form of the doubly-excited amplitudes which are expanded in the basis of largest magnitude eigenvectors of the MP2 or MP3 amplitudes. This approach enables a substantial compression of the amplitudes with only minor loss of accuracy. However, the formal scaling of the computational costs with the system size ($N$) is unaffected in comparison with the conventional CCSD theory ($\propto N^6$) due to presence of some terms quadratic in the amplitudes. We show how to solve this problem, exploiting the fact that their effective rank increases only linearly with the system size and reduce the scaling of the RR-CCSD iterations down to the level of $N^5$. This is combined with an iterative method of finding dominant eigenpairs of the MP2 or MP3 amplitudes which eliminates the necessity to perform the complete diagonalization. Next, we consider the evaluation of the perturbative corrections to the CCSD energies resulting from triply excited configurations. The triply-excited amplitudes present in the CCSD(T) method are decomposed to the Tucker-3 format using the higher-order orthogonal iteration (HOOI) procedure. This enables to compute the energy correction due to triple excitations non-iteratively with $N^6$ cost. The accuracy of the resulting rank-reduced CCSD(T) method is studied both for total and relative correlation energies of a diverse set of molecules. Accuracy levels better than 99.9\% can be achieved with a substantial reduction of the computational costs. Concerning the computational timings, break-even point between the rank-reduced and conventional CCSD implementations occurs for systems with about $30-40$ active electrons.

description: Wire sawing is the most common technology to fabricate silicon wafers in the current solar cell
industry. The sawing performance is determined by operating parameters such as the wire speed, the table speed and
the wire tension besides the wire types and the wearing status. In order to enhance the cutting performance as well as
to maintain the mechanical stability, those parameters are usually adjusted by a predefined recipe along the cutting
process. In this study, the material removal process was numerically simulated along the cutting time. The simulation
was used to identify the low cutting efficiency regime. The adjusted recipe has been proved by experiments to
demonstrate the validity of the numerical modeling.

description: We study topological charge pumping in one-dimensional quasiperiodic systems. Since these systems lack periodicity, we cannot use the conventional approach based on the topological Chern number defined in the momentum space. Here, we develop a general formalism based on a real space picture using the so-called Bott index. We extend the Bott index that was previously used to characterize quantum Hall effects in quasiperiodic systems, and apply it to topological charge pumping in quasiperiodic systems. The Bott index allows us to systematically compute topological indices of charge pumping, regardless of the detail of quasiperiodic models. We apply this formalism to the Fibonacci-Rice-Mele model which we made from Fibonacci lattice, a well-known quasiperiodic system, and Rice-Mele model. We find that these quasiperiodic systems show topological charge pumping with a multi-level behavior due to the fractal nature of the Fibonacci lattice. Such multi-level pumping behaviors can be understood by a real space renormalization group analysis.

description: Correlation between efficiency of InGaAs/GaAsP multiple quantum well (MQW) solar cells and their
average strains has been investigated by in situ wafer curvature and ex situ (-2 -2 4) x-ray reciprocal space mapping
(RSM). The average strain were varied by either In content in InGaAs wells or thickness of GaAsP barriers. Lattice
imperfections, including point defects and dislocation, were considerably a major reason of performance degradation
of strained MQW solar cells. Hence, strain balanced MQW solar cell exhibited the best performance. Average strains
as evaluated by both methods were in a good agreement. In situ curvature measurement is indeed an effective and
preferable technique for growth of InGaAs/GaAsP MQW considering strain-balancing issue.
Examining the Association Between Social Media and Violent Extremism: A Social Learning Approach

description: In recent years, the use of social media has become more prevalent across the United States. Social media, through the use of personalization algorithms, allows for exposure to extremist content and is able to create intimate groups, where like-minded individuals can communicate with each other. This study considers that, though some traditional theorists posit that learning only occurs in face to face contexts, the elements of learning described in social learning theory may also be present online. Using a set of logistic regressions to test the association between exposure to social media and personalization algorithms and violent extremism, I find (1) exposure to social media and to personalization algorithms is positively correlated with violent extremism and (2) the relationships between exposure to social media and personalization algorithms and violent extremism are explained by age, foreign fighter status and the year of extremist behavior. I discuss the implications of these findings for theory, future research and policy.

description: For the purpose of assessing the expected energy output of Photovoltaic (PV) Power Stations, several calculation programs are in use. They all aim to describe the energetic losses which arise from the chosen system configuration and the technical properties of the components used and intend to generate reliable Performance Ratio (PR) values. However, assessing the PR is just half of the challenges, which have to be addressed within an Energy Yield Assessment. Determining the site-specific, meteorological conditions – appropriate for the period of operation considered – could be the even more difficult task. Besides deviations between long-term datasets from different sources, as governed by long-term variations, the characteristics of the data available may lead to significant varying results, too. The present work uses irradiation data from several sources and two different calculation programs to focus on the impact these differences induce with regard to the Performance Ratio calculated and the energy output expected for a given PV Power Station. It highlights that the main reason for the resulting energy output differences can be found in the long-term global irradiation data applied. Furthermore, as a consequence, it demonstrates that consideration of long-term variations of annual global irradiation is of great significance for reliable Energy Yield Assessments.

description: We demonstrate that a Peierls dimerization can occur in ferromagnetic spin chains activated by thermal fluctuations. The dimer order parameter and entanglement measures are studied as functions of the modulation of the magnetic exchange interaction and temperature, using a spin-wave theory and the density-matrix renormalization group. We discuss the case where a periodic modulation is caused by spin-phonon coupling and the case where electronic states effectively induce such a modulation. The importance of the latter for a number of transition metal oxides is highlighted.

description: In this paper we present our new approach in laser ablation for local front-side openings: planar metal
contact areas formed with laser assistance in combination with wet chemical treatment. The benefits of this new
process sequence are the generation of fine-lined and self-aligned metal contacts with high conductivity, the creation
of buried contacts to reduce the shadow losses, and the possibility of forming a selective emitter (depending on the
diffusion-barrier layer) without additional steps.

description: The cost per watt peak of solar modules must be reduced to ensure long term commercial viability.
Manufacturing costs can be reduced by using thinner silicon wafers. Thin wafers are also advantageous in that they
have lower bulk recombination. However, as wafer thickness is reduced, surface recombination becomes a limiting
factor for cell efficiency. The advantages of thin cells can be exploited by incorporating a good rear passivation. The
FP7 funded project ‘20Plμs’, aims to produce well passivated 20% efficiency solar cells on 100μm Cz
monocrystalline wafers.In this paper we describe the integration of a AlOx/SiOx rear passivating layer into a high
efficiency LGBC solar cell structure fabricated using 100μm and 160μm thick industry standard Cz Si. These cells
have significantly higher open circuit voltages (Voc) and short-circuit current densities (Jsc) than standard LGBC cells
and hence show potential for higher cell efficiencies.
