description: Electroluminescence imaging experienced uprising use in the last years. In future photovoltaic plants the time-consuming connection of power supplies to photovoltaic module strings could be overcome by use of inverters with bi-directional functionality, allowing backpowering of connected module strings directly. During backpowering, the limits of the power supply must be considered. As temperature influences the open-circuit voltage, it is a crucial parameter to remain in these limits. The EL inspection itself impacts the solar cells temperature, as they warm up during the process, resulting in a shift of open circuit voltage. This work investigates the heating of a hetero junction photovoltaic module during electroluminescence inspection. The saturation temperature is estimated by energy balance calculations and experimentally verified to be around 20°C, with resulting voltage drop above 2 V. The importance of this is not only to verify that the measurement is within the limits of the power supply but also to consider changes of the recorded luminescence intensity due to the temperature, shown to have a decrease of up to 4 %.

description: We study the impact of bound state formation on dark matter annihilation rates in models where dark matter interacts via a light mediator, the dark photon. We derive the general cross section for radiative capture into all possible bound states, and point out its non-trivial dependence on the dark matter velocity and the dark photon mass. For indirect detection, our result shows that dark matter annihilation inside bound states can play an important role in enhancing signal rates over the rate for direct dark matter annihilation with Sommerfeld enhancement. The effects are strongest for large dark gauge coupling and when the dark photon mass is smaller than the typical momentum of dark matter in the galaxy. As an example, we show that for thermal dark matter the Fermi gamma ray constraint is substantially increased once bound state effects are taken into account. We also find that bound state effects are not important for dark matter annihilation during the freeze out and recombination epochs.

description: In this paper, a novel embedded software package, called RoboPV, is introduced for autonomous aerial monitoring of large-scale photovoltaic (PV) plants. RoboPV enables aerial robots to automatically perform aerial monitoring of PV plants, from optimal trajectory planning to real-time fault detection using deep neural network models. This software package is made of four systematically integrated parts: boundary detection, path planning, dynamic processing, and fault detection. The first requirement of efficient path planning is to identify the PV plant boundary closed curve. This requirement is prepared by an encoder-decoder deep learning architecture which is trained by labeled real flight aerial images of PV plants. Subsequently, a novel path planning algorithm is conducted by RoboPV to design an optimal flight path with full coverage of whole regions of the PV plant. Another deep neural network model has been also trained for real-time fault detection in PV plants through PV faults labeled dataset. Using this highly precise trained neural network, aerial images are analyzed in real-time during the flight and when a probable fault is detected, RoboPV commands the aerial robot to maneuver and concentrate more on the detected fault. In this study, several decision-making and maneuver algorithms are developed for various real-world flight conditions to improve the performance of RoboPV during an autonomous aerial inspection. RoboPV is a modular processing library that can be installed on any micro-computer processor with a low computational burden. Moreover, supporting the MAVLink communication protocol enables RoboPV to connect with an intelligent Pixhawk flight autopilot and navigate a wide range of multi-rotors. To demonstrate the performance of RoboPV, a six degrees of freedom dynamic model of a multi-rotor has been developed in a Simulink environment, and processor in the loop (PIL) tests have been performed for aerial monitoring of two different real megawatt-scale PV plants.

description: Vortex core polarity switching in NiFe disks has been evidenced using an all-electrical rectification scheme. Both simulation and experiments yield a consistent loss of the rectified signal when driving the core at high powers near its gyrotropic resonant frequency. The frequency range over which the loss occurs grows and shifts with increasing signal power, consistent with non-linear core dynamics and periodic switching of the core polarity induced by the core attaining its critical velocity. We demonstrate that core polarity switching can be impeded by displacing the core towards the disk's edge where an increased core stiffness reduces the maximum attainable core velocity.

description: In this work we give an overview of the module monitoring results achieved within the H2020 funded project called HighLite. A dedicated online monitoring platform has been developed for the project to group and treat the data from all partners with homogeneous procedures. Monitoring of advanced prototype modules developed in the project and based on various cells and interconnection approaches, like silicon-heterojunction (SHJ)-shingle, TopCon-shingle, cut interdigital back-contact cells (cut-IBC) are reported. We describe key learnings from monitoring modules for various applications including building-applied PV (BAPV) and building-integrated PV (BIPV). Annual energy yield up to 1900 kWh/kWp is expected in Cadarache (France) based on HighLite PV technology. Temperature corrected performance ratios are used for a ranking of the new technologies against the reference PERC modules.

description: We present the statistical analysis of the properties of gamma-ray bursts with measured host galaxy redshifts and peaked optical light curves in proper frames of reference. The optical transients are classified by comparing the time lag of the optical peak relative to the GRB trigger with the duration of the gamma-ray emission itself. The results of the correlation analysis of all possible pairs of energy, spectral, and temporal characteristics of both gamma-ray and optical emissions are given. We specify the pairs of the parameters with correlation coefficients greater than 50 % at significance levels better than 1 %. The following empirical relations, obtained for the first time, are specifically discussed: a correlation between the peak optical afterglow $R$ band luminosity and redshift $L_{R} \propto (z+1)^{5.39 \pm 0.74}$ and a correlation between the peak luminosity of the prompt optical emissions and the time of the peak $L_{R} \propto T_{\rm peak}^{-3.85 \pm 1.22}$. We also analyze the similarity of the relationships between the peak optical luminosity and the isotropic equivalent of the total energy of gamma-ray bursts for afterglows ($L_{R} \propto E_{\rm iso}^{1.06 \pm 0.22}$) and for prompt optical emissions ($L_{R} \propto E_{\rm iso}^{1.59 \pm 0.21}$).

description: Cardiac disease is one of the prominent reasons of deaths worldwide. The timely de-
tection of arrhythmias, one of the highly prevalent cardiac abnormalities, is very important
and promising for treatment. Electrocardiography (ECG) is well applied to probe the car-
diac dynamics, nevertheless, it is still challenging to robustly detect the arrhythmia with
automatic algorithms, especially when the noise may contaminate the signal to some extent.
In this research study, we have not only built and assessed different neural network models
to understand their capability in terms of ECE-based arrhythmia detection, but also com-
prehensively investigated the detection under different kinds of signal-to-noise ratio (SNR).
Both Long Short-Term Memory (LSTM) model and Multi-Layer Perception (MLP) model
have been developed in the study. Further, we have studied the necessity of fine-tuning
of the neural network models, which are pre-trained on other data and demonstrated that
it is very important to boost the performance when ECG is contaminated by noise. In
the experiments, the LSTM model achieves an accuracy of 99.0%, F1 score of 97.9%, and
high precision and recall, with the clean ECE signal. Further, in the high SNR scenario,
the LSTM maintains an attractive performance. With the low SNR scenario, though there
is some performance drop, the fine-tuning approach helps performance improvement criti-
cally. Overall, this study has built the neural network models, and investigated different
kinds of signal fidelity including clean, high-SNR, and low-SNR, towards robust arrhythmia
detection.

description: In 2013 we conducted a large multi-wavelength campaign on the archetypical Seyfert 1 galaxy NGC 5548. Unexpectedly, this usually unobscured source appeared strongly absorbed in the soft X-rays during the entire campaign, and signatures of new and strong outflows were present in the almost simultaneous UV HST/COS data. Here we carry out a comprehensive spectral analysis of all available XMM-Newton observations of NGC 5548 (for a total of ~763 ks) in combination with 3 simultaneous NuSTAR obs. We obtain a best-fit composed by i) a weakly varying flat (Gamma~1.5-1.7) power-law component; ii) a constant, cold reflection (FeK + continuum) component; iii) a soft excess, possibly due to thermal Comptonization; and iv) a constant, ionized scattered emission-line dominated component. Our main findings are that, during the 2013 campaign, the first 3 of these components appear to be partially covered by a heavy and variable obscurer located along the l.o.s. that is consistent with a multilayer of cold and mildly ionized gas. We characterize in detail the short timescale (~ks-to-days) spectral variability of this new obscurer, and find it is mostly due to a combination of Nh and Cf variations, on top of intrinsic power-law variations. In addition, our best-fit spectrum is left with several (but marginal) absorption features at rest-frame energies ~6.7-6.9 keV and ~8 keV, as well as a weak broad emission line feature redwards of the 6.4 keV emission line. These could indicate a more complex underlying model, e.g. a P-Cygni-type profile if allowing for a large velocity and wide-angle outflow. These findings are consistent with a picture where the obscurer represents the manifestation along the l.o.s. of a multilayer of gas that is likely outflowing at high speed, and simultaneously producing heavy obscuration and scattering in the X-rays and broad absorption features in the UV.

description: This study investigated variation in condensation (dew) and its effect on PV soiling, on a global level. Qualitatively, it is well known that condensation plays several roles in PV soiling: capillary adhesion and cementation cause dust particles to stick to the surface of modules, while run-off of dew droplets can clean them. However because outdoor condensation sensors are rare, the quantitative link between condensation and soiling is less known. Here, we developed a low-cost sensor to measure condensation outdoors and deployed it at seven PV test sites worldwide, spanning different climates. It was found that the condensation data helped explain differences in soiling rate between geographical locations (sites with higher average condensation had higher average soiling rates), however it did not explain differences in soiling rate at a given location over time (there was negligible correlation between daily soiling rate and daily condensation, at each location). Regarding performance of the sensor itself, it produced stable and expected measurements of the daily maximum condensation, however at four sites the daily minimum values suggested gradual contamination or drift of the sensor. It was concluded that condensation does help explain differences in PV soiling rates between different locations, but it cannot be used (in a simplistic way, at least) to predict daily variation each location’s soiling rate.

description: After installation of a PV system, the question arises if it works correctly. Comparing the yield with some prediction gives a hint if the system is OK, but takes a long time and depends on the weather during that period. Also the effect of shading by trees or buildings is hard to estimate and often not included in the prediction. We present a solution based on the evaluation of the power curve of the PV system from a sunny day. The peak power of the PV system is obtained by simulating this power curve using the peak power as a fit parameter. The simulation uses the public library pvlib python including the clear sky model of Ineichen and Perez, and a database for the air turbidity. The temperature of the PV modules is calculated from air temperature and wind speed. The software with its graphical user interface for Microsoft WindowsTM is freely available. The simulation of irradiance and module temperature is compared to experimental data. As an example, the peak power of some newly installed PV systems was evaluated. Furthermore, a degradation analysis of the peak power over a 10-year period of a test system is performed.

description: We describe a micromachining process to allow the coupling of an array of single-mode telecommunication fibers to individual superconducting nanowire single photon detectors (SNSPDs). As proof of principle, we show the integration of four detectors on the same silicon chip, including two standard single-section nanowire detectors and two superconducting nanowire avalanche photodetectors (SNAPs) with modified series structure without external inductor, and their performances are compared. The SNAP shows saturated system detection efficiency of 16% while the dark count rate is less than 20 Hz, without the use of photon-recycling reflectors. The SNAP also demonstrates doubled signal-to-noise ratio, reduced reset time (~ 4.9 ns decay time) and improved timing jitter (62 ps FWHM) compared to standard SNSPDs.

Operation, Performance and Maintenance of PV Systems

description: 8th World Conference on Photovoltaic Energy Conversion; 1089-1093
description: Tools that help automate operation and maintenance (O&M) processes are fundamental to expanding the ability of service providers to meet the demand of the growing number of PV systems. Within maintenance processes, the daily routine of online monitoring is a repetitive and time-consuming activity that relies heavily on manual analysis by specialized personnel. Automating this routine is challenging and requires a reliable automatic fault detection (AFD) system. This study proposes an AFD system consisting of nine algorithms primarily grounded in experts' knowledge that analyze different aspects of the PV system for abnormal behavior. The algorithms were individually developed, tested, and validated with the help of 5 years of data, including tickets created by manual monitoring, from 80 rooftop PV systems. The complete AFD system was then tested by monitoring 170 systems for one month, where it correctly detected 99% of the problems and issued less than 12% of false alerts. It also identified problems (13.2% of the total of actual faults) that passed unnoticed by conventional monitoring. The proposed AFD system provides a promising solution for automatizing part of the online monitoring routine and helps operators expand their capacity to monitor more systems.

description: Non-governmental organizations (NGOs) operate in the Brazilian Amazon, mobilizing actors and resources to promote sustainability, mainly by supporting the construction of alternative farming systems. The main efforts are focused on reducing deforestation by means of agroforestry projects, which are introduced as alternatives to extensive livestock farming. This study analyzes the strategies adopted by the Amazonian Institute of Conservation and Sustainable Development and the World Wide Fund for Nature to engage farmers and other actors in their programs. The study was conducted in Apuí, one of the target municipalities of public policies aimed at combating deforestation. The findings reveal that these NGOs adapt their strategies throughout time in face of expressive institutional complexity in local and macro spheres. Acting as “institutional entrepreneurs,” NGOs have changed their discourses from an eminently preservationist focus to one that is more adapted to the economic concerns of local actors and connected to their moral and cultural norms, which also imply a reframing of “sustainability” through a scientific discourse that embodies a more technocratic approach to forest conservation.

description: To detect degradation of photovoltaic systems at an early stage, precise performance determinations are essential. Current-voltage measurements on single modules in indoor labs under well-defined conditions are state-ofthe-art. However, this method causes a logistical and economic effort. On-site measurements reduce the effort but are prone to error because of poorly determinable test conditions: The detected temperature on the backside of modules as well as the irradiance detected by pyranometer in tilted module plane usually differs from the actual operating conditions. In consequence, the accuracy of measured current-voltage characteristics is poor. A precise on-site power determination is achieved by a self-reference algorithm. Improvements by self-referencing are not achieved by correcting the raw electrical data, but by replacing the measured test conditions (temperature and irradiance) with effective data. These effective values correspond better to the actual module irradiance and temperature values. Furthermore, precise power determination of photovoltaic arrays requires to identify and exclude temporarily deformed current-voltage curves from consideration, as it can arise from non-uniform irradiation within array like shading. In this paper, the application of a digital curve filter is reported and performance determinations by a self-reference algorithm are demonstrated on a photovoltaic array. We review and discuss the measurement concept in terms of its ease of use.

description: For analyzing high volumes of operational data from grid-connected PV systems, meanwhile, algorithms help to detect exceptional deviations from normal behavior. Machine learning methods in particular are used to overcome complex relationships within the data. One category are artificial neural networks, which are utilized to map the specific system performance as a function of environmental parameters. This paper investigates the influence of the data used for training on the detectability of yield deviations. Based on four different training scenarios the effect of missing data, the selection of irradiance sensor data, the data resolution as well as the monitoring resolution are analyzed in detail. Recommendation in respect to spatial irradiance sensor coverage and data aggregation will be given. This paper will explain the approach of defect detection, the data modification as well the impact of training quality on the detectability.

description: Aims. We investigate the feasibility of planetesimal growth in circumbinary protoplanetary disks around the observed systems Kepler- 16 and Kepler-34 under the gravitational influence of a precessing eccentric gas disk. Methods. We embed the results of our previous hydrodynamical simulations of protoplanetary disks around binaries into an N-body code to perform 3D, high-resolution, inter-particle gravity-enabled simulations of planetesimal growth and dynamics that include the gravitational force imparted by the gas. Results. Including the full, precessing asymmetric gas disk generates high eccentricity orbits for planetesimals orbiting at the edge of the circumbinary cavity, where the gas surface density and eccentricity have their largest values. The gas disk is able to efficiently align planetesimal pericenters in some regions leading to phased, non-interacting orbits. Outside of these areas eccentric planetesimal orbits become misaligned and overlap leading to crossing orbits and high relative velocities during planetesimal collisions. This can lead to an increase in the number of erosive collisions that far outweighs the number of collisions that result in growth. Gravitational focusing from the static axisymmetric gas disk is weak and does not significantly alter collision outcomes from the gas free case. Conclusions. Due to asymmetries in the gas disk, planetesimals are strongly perturbed onto highly eccentric orbits. Where planetesimals orbits are not well aligned, orbit crossings lead to an increase in the number of erosive collisions. This makes it difficult for sustained planetesimal accretion to occur at the location of Kepler-16b and Kepler-34b and we therefore rule out in-situ growth. This adds further support to our initial suggestions that most circumbinary planets should form further out in the disk and migrate inwards.

description: We have performed micromagnetic simulations of the vortex gyrotropic mode resonance in a range of disk geometries subject to spatially uniform out-of-plane magnetic fields. For disks of small lateral dimensions, we observe a drop-off in the mode's frequency for field amplitudes approaching the disk saturation field. This non-linear frequency response is shown to be associated with an increased vortex core deformation, which results from the demagnetizing field created when the core is shifted laterally. Such deformation results in an increase in the average out-of-plane magnetization of the displaced vortex state, which through an exchange contribution, leads to a sharp decrease in the vortex stiffness coefficient. It is this decrease in the vortex stiffness coefficient which leads to the non-linear field dependence of the gyrotropic mode frequency.

description: The anthropogenic climate changes render zero-energy buildings mandatory to suppress the emission of CO2 but the monotonous design of conventional photovoltaic modules has not been welcomed by architects. In order to improve the public acceptance of conventional photovoltaic modules, photovoltaic modules have begun decorated with LEDs or even used as the background of LED modules, acting as media façade with an information function. However, the lifetime mismatch between photovoltaic and LED modules has demanded replaceable LED modules with a minimum shading loss. In this study, an in-house developed LED module is presented, which is designed to be assembled and replaced like LEGO bricks when it is malfunctional. The grid-type design of an LED module also dwindles the shading loss of a photovoltaic module. By applying a reflective coating on the grid walls of an LED module, the sunlight at an incident angle will be re-captured by a photovoltaic module, preserving the photoconversion efficiency of a photovoltaic module.

AR Content Management System

description: The NextGen AR applications are built and demonstrated in two NextGen sites (Athens and Gotland) while an effort has been made to build and demonstrate the app in a virtual demo case to enable other sites to adopt a sustainable and circular water use regardless of their location. The AR applications aim to drastically increase the learning value of the showcases by making visible ‘hidden’ or ‘intangible’ elements of the cycle and demonstrated solution to visitors. The AR applications are developed in a generic format that is fully customizable for any NextGen site that would be interested in later stages of the project. The mobile AR application accompanied by the AR Content Management System allows easy customization of the content and its positioning on the points of interest. Furthermore, gamification mechanisms are added in order to engage the users and increase the learning outcome of the application. The UX/UI designs are presented in this document, followed by an overview of the AR-CMS with the addition of possible PoIs deployed in Athens, Gotland and the virtual demo.

description: Artificial Intelligence methods are overwhelming every R&D area where data are used, including PV module performances. Here we propose to test new Artificial Intelligence (AI) methods in order to estimate the degradation rate of PV Modules. Among these AI methods, we implemented Long Short Term Memory (LSTM) neural network. In the learning step, known degradation rates were simulated in a digital power plant and by using meteorological data set of an EDF Renewables outdoor test facility (almost 4 years of data, PV module production & meteorological conditions). Then, these generated data were used to teach AI systems. In the test step, the AI is expected to assess ou find the degradation rate by analyzing a 3 years-long dataset. In addition, we developed a method for estimating electrical parameters (Isc, nds, Rs) and another method for saving the state of plant in order to replay it later with different meteorological data. The results are promising with the last method and show the performance and efficiency of AI when estimating degradation rate. These methods have many interests, but one of the most important is to combine PV model and the exact field meteorological dataset to simulate various degradation amplitudes and shapes in order to feed an AI. By this way and knowing the meteorological conditions, AI can learn and propose the expected PV behavior (every shape is normalized) and interpolate the degradation rate corresponding to the field values of PV module production. A final comparison is done with data from EDF R’s test zone in US by comparing the estimated AI degradation rate and the STC (Standard Test Conditions) flashes of modules carried out recently.
