description: Fragmentation and fission of giant molecular clouds occasionally results in a pair of gravitationally bound star clusters that orbit their mutual centre of mass for some time, under the influence of internal and external perturbations. We investigate the evolution of binary star clusters with different orbital configurations, with a particular focus on the Galactic tidal field. We carry out $N$-body simulations of evolving binary star clusters and compare our results with estimates from our semi-analytic model. The latter accounts for mass loss due to stellar evolution and two-body relaxation, and for evolution due to external tides. Using the semi-analytic model we predict the long-term evolution for a wide range of initial conditions. It accurately describes the global evolution of such systems, until the moment when a cluster merger is imminent. $N$-body simulations are used to test our semi-analytic model and also to study additional features of evolving binary clusters, such as the kinematics of stars, global cluster rotation, evaporation rates, and the cluster merger process. We find that the initial orientation of a binary star cluster with respect to the Galactic field, and also the initial orbital phase, are crucial for its fate. Depending on these properties, the binaries may experience orbital reversal, spiral-in, or vertical oscillation about the Galactic plane before they actually merge at $t\approx100$~Myr, and produce rotating star clusters with slightly higher evaporation rates. The merger process of a binary cluster induces an outburst that ejects $\sim10\%$ of the stellar members into the Galactic field.

description: In this work, we present and validate a machine learning approach for estimating power loss in monocrystalline silicon PV cells due to cell cracks. The primary focus is selection and evaluation of robust and accurate prediction-features derived from electroluminescence (EL) images of solar cells. To achieve this, we have experimentally created training and validation EL and I-V measurements datasets of cells with two to up to five busbars, with different extents of cell crack degradation. We have evaluated simple features derived from the cells' luminescence histogram, which are easy to compute; these are the cell inactive area, the mean, standard deviation (STD), skewness, and kurtosis. Learning models are then trained against cell I-V measurements and validated. This cell-level approach has the advantage of being scalable so that it could be used to estimate the power loss of a full PV module based on a module EL image that is segmented in cell images. Similarly, this bottom-up approach could facilitate the development of more generalizable machine algorithms, where just one model can be used to simulate power no matter the size of the module, number, layout, or type of the cracked cells. As a baseline, a linear regression approach was attempted, which yielded a R2 score of 0.85 and a maximum error of 0.26. These results were subsequently improved by applying a 2nd degree polynomial linear regression and a custom non-linear regression to 0.869 of R2 and 0.17 of maximum error. The model selection has been chosen from a statistical exploratory analysis of the dataset, where it has been demonstrated that mono-crystalline cells of with different number of busbars behave differently in terms of histogram features correlations with the output power, and that adding a classifier variable as the busbar number as a predictor it is possible to account for the non-linearity of each cell type and model it accordingly.

PV Module Performance – Modelling, Testing, Standards

description: BIPV (Building Integrated Photovoltaics) systems play an important role in generating electricity for net-zero energy buildings. Since BIPV modules and systems are fully integrated into the building envelope, their rear side is exposed to no or low ventilation, leading to increased operating temperature. Therefore, the performance of the modules – which decreases with increasing temperatures – is reduced, and the durability of the module – and its components (e.g. encapsulant, backsheet etc.) – may be impacted. Over the years, three different BIPV mock-ups have been installed at SUPSI (in Southern Switzerland) in different configurations: open-rack, BIPV-ventilated (partial ventilation) and BIPV-insulated (no ventilation) to investigate the impact of the operating temperature on the long-term performance of different BIPV modules. In this work, first, we show that since larger thermal stress accelerates UVinduced degradation of EVA (discoloration), there could be loss in Isc in BIPV configurations. Secondly, due to larger thermo-mechanical stress, there could be damaged cells and metallization, which causes loss in FF. Additionally, operating in a BIPV configuration does not mean that there will be faster degradation. There could be faster degradation only if there are larger thermal and-or thermo-mechanical stresses.

description: We extend the semiclassical theory of short periodic orbits [Phys. Rev. E {\bf 80}, 035202(R) (2009)] to partially open quantum maps. They correspond to classical maps where the trajectories are partially bounced back due to a finite reflectivity $R$. These maps are representative of a class that has many experimental applications. The open scar functions are conveniently redefined, providing a suitable tool for the investigation of these kind of systems. Our theory is applied to the paradigmatic partially open tribaker map. We find that the set of periodic orbits that belong to the classical repeller of the open map ($R=0$) are able to support the set of long-lived resonances of the partially open quantum map in a perturbative regime. By including the most relevant trajectories outside of this set, the validity of the approximation is extended to a broad range of $R$ values. Finally, we identify the details of the transition from qualitatively open to qualitatively closed behaviour, providing an explanation in terms of short periodic orbits.

description: The paper "The Future of Archives: Blockchain Technology in the Archival Space" by Anna Valenti explores how Blockchain technology might reshape archival practices. It examines whether Blockchain can enhance archival processes by providing a decentralized, immutable system for record-keeping. However, it also raises concerns about the potential risks, such as the loss of human context and narrative, algorithmic bias, and the transformation of archives into automated, emotionless repositories. The paper argues that while Blockchain could improve accessibility and transparency, it may also fundamentally alter the traditional concept of archives.

description: Building integrated photovoltaics (PV) is among the major PV technologies being pursued to align with the energy efficiency buildings and net-zero emission policies. Semi-transparent solar cells could be key components to achieve these targets and efforts are underway to develop novel PV absorbers and devices with the priority of materials’ abundance, cost and stability. Sb2S3 thin films are promising PV absorbers owing to their superior optoelectronic properties, stability and availability of raw materials. However, the conventional expensive hole conductors like P3HT and Spiro-OMeTAD coupled with their post-processing needs and stability issues could be obstacles for Sb2S3 solar cells. In this study, cost-effective and transparent fluorene and thiophene-based hole transport materials (HTM) are explored in Sb2S3 solar cells. HTMs are spin coated to fabricate solar cells in the superstrate configuration (Glass/FTO/TiO2/Sb2S3/HTM/Au) wherein TiO2 and Sb2S3 are ultrasonic spray deposited. Solar cells with new HTMs have yielded similar power conversion efficiencies (3.8-3.9 %) compared to P3HT-based cells (3.7%) while exhibiting 20-25 % enhanced average visible transmittance (400-800 nm) in the device stack without the metal contact. Optical properties and band energetics of individual layers demonstrate that the new cost-effective HTMs exhibit favourable band off-set for application in semi-transparent Sb2S3 solar cells.

description: Epitaxial semiconductor-superconductor hybrid materials are an excellent basis for studying mesoscopic and topological superconductivity, as the semiconductor inherits a hard superconducting gap while retaining tunable carrier density. Here, we investigate double-quantum-dot devices made from InAs nanowires with a patterned epitaxial Al two-facet shell that proximitizes two gate-defined segments along the nanowire. We follow the evolution of mesoscopic superconductivity and charging energy in this system as a function of magnetic field and voltage-tuned barriers. Inter-dot coupling is varied from strong to weak using side gates, and the ground state is varied between normal, superconducting, and topological regimes by applying a magnetic field. We identify the topological transition by tracking the spacing between successive cotunneling peaks as a function of axial magnetic field and show that the individual dots host weakly hybridized Majorana modes.

description: One of the most accurate primary calibration methods for solar cells is the direct sunlight method (DSM), using the direct light of the sun as light source. We present a measurement device that scales the DSM method to the size of PV modules. The setup provides a light field of the size of 2.5 x 2.5 m² and is therefore capable of measuring large-sized PV modules based solar cells with an area of 210 mm x 210 mm. Technically, the setup consists of a rectangular tube with a size of 4 m x 4 m x 7.2 m, capable of tracking the sun. In addition, the PV module holder inside the tube can be tilted relative to the sun, enabling us to perform an angle of incidence measurement of the device under test. We present our first angular measurements of a half-cut solar module and a power measurement as first step towards a primary calibration of the same module to showcase the capabilities of our new setup.

description: Multi-omic studies ranging from genomics, transcriptomics (e.g., gene expression) to proteomics data exploration have been widely applied to interpret findings from genome wide association studies (GWAS) of Alzheimer's disease (AD). However, previous studies examine each -omics data type individually and the functional interactions between genetic variations, genes and proteins are only used after discovery to interpret the findings, but not beforehand. In this case, multi-omic findings are likely not functionally related and therefore it is challenging for result interpretation. To handle this challenge, we present new modularity constrained least absolute shrinkage and selection operator (M-LASSO), new modularity constrained logistic regression (M-Logistic), new interpretable multi-omic graph fusion neural network model (MoFNet) and new transfer learning framework integrated graph fusion neural network model (TransFuse) to integrate prior biological knowledge to model the functional interactions of multi-omic data. These approaches aim to identify functional connected sub-networks predictive of AD. In this thesis, the intrepretable model MoFNet and TransFuse incorporate prior biological connected multi-omics network, and for the first time model the dynamic information flow from deoxyribonucleic acid (DNA) to ribonucleic acid (RNA) and proteins. While applying the proposed models on multi-omic data from the religious orders study/memory and aging project (ROS/MAP) cohort, MoFNet and TransFuse outperformed all other state-of-art classifiers. Instead of targeting individual markers, the proposed methods identified multi-omic sub-networks associated with AD. MoFNet and TransFuse, produced sub-network and pathway findings that were robustly validated in another independent cohort. These identified gene/protein networks highlight potential pathways involved in AD pathogenesis and could offer systematic overview for understanding the molecular mechanisms of the disease. Investigating these identified pathways in more detail could help uncover the mechanisms causing synaptic dysfunction in AD and guide future research into potential therapeutic targets.

description: This paper proposes a robust fast multi-band image fusion method to merge a high-spatial low-spectral resolution image and a low-spatial high-spectral resolution image. Following the method recently developed in [1], the generalized Sylvester matrix equation associated with the multi-band image fusion problem is solved in a more robust and efficient way by exploiting the Woodbury formula, avoiding any permutation operation in the frequency domain as well as the blurring kernel invertibility assumption required in [1]. Thanks to this improvement, the proposed algorithm requires fewer computational operations and is also more robust with respect to the blurring kernel compared with the one in [1]. The proposed new algorithm is tested with different priors considered in [1]. Our conclusion is that the proposed fusion algorithm is more robust than the one in [1] with a reduced computational cost.

A simple scheme to implement a nonlocal turbulent convection model for the convective overshoot mixing

Publisher: name: arXiv
Year: 2016
Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)

description: The classical 'ballistic' overshoot models show some contradictions and are not consistence with numerical simulations and asteroseismic studies. Asteroseismic studies imply that overshoot is a weak mixing process. Diffusion model is suitable to deal with it. The form of diffusion coefficient in a diffusion model is crucial. Because the overshoot mixing is related to the convective heat transport (i.e., entropy mixing), there should be a similarity between them. A recent overshoot mixing model shows consistence between composition mixing and entropy mixing in overshoot region. A prerequisite to apply the model is to know the dissipation rate of turbulent kinetic energy. The dissipation rate can be worked out by solving turbulent convection models (TCMs). But it is difficult to apply TCMs because of some numerical problems and the enormous time cost. In order to find a convenient way, we have used the asymptotical solution and simplified the TCM to be a single linear equation for turbulent kinetic energy. This linear model is easy to be implemented in the calculations of stellar evolution with ignorable extra time cost. We have tested the linear model in stellar evolution, and have found that the linear model can well reproduce the turbulent kinetic energy profile of full TCM, as well as the diffusion coefficient, abundance profile and the stellar evolutionary tracks. We have also studied the effects of different values of the model parameters and have found that the effect due to the modification of temperature gradient in the overshoot region is slight.

PV Module Performance – Modelling, Testing, Standards

description: 8th World Conference on Photovoltaic Energy Conversion; 477-479
description: A major component in the growth of developing PV markets around the world is the reliability and longevity of photovoltaic (PV) modules. The polymeric encapsulation materials' chemical and physical stability directly affects reliability. Ultraviolet Fluorescence (UVF) imaging is a technique that can detect the impacts of the polymeric encapsulant's aging directly on site at a PV plant. This research focuses on advanced imaging analysis of UVF pictures and the subsequent correlation to electrical characteristics of PV modules that have undergone longterm, accelerated aging processes particular to a certain climate. For establishing a correlation, a so called UVF area ratio was established, resulting from the typical fluorescence patterns of the encapsulant material, which arise due to stress impact (e.g.: water vapor ingress, elevated temperature, irradiation) and aging/degradation processes. The results of the data analysis demonstrate a distinct correlation between the electrical parameters and the UVF area ratio with increasing aging time. Long-term test series with different climate-specific aging processes confirm UVF area ratio correlations with power and series resistance. Hence, calculating the UVF area ratio can be used to predict the service life and electrical power dissipation of individual PV modules within a PV array, under the assumptions of the utilization of the same kind of polymeric encapsulation and backsheet materials and a similar climate.

description: Extant literature shows the way of communication and the information contained in the advertising is not strong and pertinent enough to attract the attention of the consumers. Advertising must be consistent enough so that it can be accepted and bring an effect on consumers' buying behavior when judged against information previously processed and held. This study aimed at examining the influence of demographic and socio-cultural factors, advertisement media choice used on consumers' buying behavior in selected Ethiopian private banks. We used bank age to stratify population in out attempt to capture heterogeneous behavior. Sample banks were randomly selected from each stratum while top three big branches of these banks were included purposefully. Finally grab sampling was used to capture perceptions of384 customers of which 362 (94%) were valid for farther analysis. The study used descriptive statistics, Chi-square, ANNOVA and linear regression to analyze differences among groups and effect of input variables on the outcome variable. Results indicate education and advertisement objective influence consumer buying behavior. Likewise, only broadcast media of the four media the sector uses significantly and positively influence buying behavior. Accordingly, the study concludes demographic factors, media selection and advertisement objective influencing consumer buying behavior in the Ethiopian private banking sector. Finally, we recommend private banks to focus on using broadcast media than others, persuasion advertisement objective to be more on persuasion, content attractive enough for educated, youth and middle age customers.

description: The one-bit compressed sensing framework aims to reconstruct a sparse signal by only using the sign information of its linear measurements. To compensate for the loss of scale information, past studies in the area have proposed recovering the signal by imposing an additional constraint on the L2-norm of the signal. Recently, an alternative strategy that captures scale information by introducing a threshold parameter to the quantization process was advanced. In this paper, we analyze the typical behavior of the thresholding 1-bit compressed sensing utilizing the replica method of statistical mechanics, so as to gain an insight for properly setting the threshold value. Our result shows that, fixing the threshold at a constant value yields better performance than varying it randomly when the constant is optimally tuned, statistically. Unfortunately, the optimal threshold value depends on the statistical properties of the target signal, which may not be known in advance. In order to handle this inconvenience, we develop a heuristic that adaptively tunes the threshold parameter based on the frequency of positive (or negative) values in the binary outputs. Numerical experiments show that the heuristic exhibits satisfactory performance while incurring low computational cost.

description: This study aims to validate theoretical modelling of Plasmonic Luminescent Solar Concentrators(PLSC) software so that it can be used to optimize the PLSC fabrication process. The model will also be used to optimize the overall PLSC output in terms of solar power conversion, optical efficiency, dye concentration and device configuration. The two-stage process involves initially validating the LSC simulations by matching the modelling results with experimentally observed outputs, before moving onto subsequent PLSC model validation which requires further additional inputs, the metal nanoparticle extinction spectra, and the photon density enhancement factor (PDEF). The metal nanoparticle extinction spectra were measured experimentally and as the PDEF was the final remaining variable, it was taken from the literature and altered until it fit the particles being used in this study. The results of these simulations were then compared with the indoor and outdoor experimental characterizations and after noting that the trends and key data points correlated between the two methods of testing, the model was deemed to be validated.

description: In the last 18 years PV solar power has increased from 0 to 500 GWp approximately as indicated by International Energy Agency Photovoltaic Power Systems Program IEA PVPS [13]. However, an issue that has been left aside is the maintenance of the constituent elements of a solar PV plant, this mainly because the elements are still under warranty. In particular, one of the fundamental players in a solar PV plant is the Photo Voltaic Solar Module PVSM, which usually has a guarantee of around 20 years. However, it has been proven that in practice a large number of modules have presented unexpected failures, e.g., power degradation faster than what the manufacturer considered when defining the warranty. Considering an average annual degradation of 1%, it would be expected that within the first 10 years, the PV modules of a PV plant present a 10% degradation in their performance. In this work it is carried out a characterization of the electrical behavior of a bifacial photovoltaic solar module obtained through static and transient analyses operating under no-fault and fault conditions at controlled conditions using the Flasher IV A+A+A+ Solar Simulator of Eternalsun. Later, the response of photovoltaic solar modules, for their healthy and faulty operation, were studied. As a result, it is obtained a characterization of the electrical behavior of bifacial photovoltaic solar module under nofault and fault conditions at controlled level.

description: Recently, it has been suggested in [JHEP 12(2015)003] that the Brown-York mechanism can be used to measure the quasilocal energy in Lovelock gravity. We have used this method in a system of M0-branes and show that the Brown-York energy evolves in the process of birth and growth of Lovelock gravity. This can help us to predict phenomenological events which are emerged as due to dynamical structure of Lovelock gravity in our universe. In this model, first, M0-branes join to each other and form an M3-brane and an anti-M3-branes connected by an M2-brane. This system is named BIon. Universes and anti-universes live on M3-branes and M2 plays the role of wormhole between them. By passing time, M2 dissolves in M3's and nonlinear massive gravities, like Lovelock massive gravity, emerges and grows. By closing M3-branes, BIon evolves and wormhole between branes makes a transition to black hole. During this stage, Brown-York energy increases and shrinks to large values at the colliding points of branes. By approaching M3-branes towards each other, the square energy of their system becomes negative and some tachyonic states are produced. To remove these states, M3-branes compact, the sign of compacted gravity changes, anti-gravity is created which leads to getting away of branes from each other. Also, the Lovelock gravity disappears and it's energy forms a new M2 between M3-branes. By getting away of branes from each other, Brown-York energy decreases and shrinks to zero.

description: Topological invariants such as characteristic classes are an important tool to aid in understanding and categorizing the structure and properties of algebraic varieties. In this note we consider the problem of computing a particular characteristic class, the Chern-Schwartz-MacPherson class, of a complete simplicial toric variety X defined by a fan from the combinatorial data contained in the fan. Specifically, we give an effective combinatorial algorithm to compute the Chern-Schwartz-MacPherson class of X, in the Chow ring (or rational Chow ring) of X. This method is formulated by combining, and when necessary modifying, several known results from the literature and is implemented in Macaulay2 for test purposes.

description: Experimental vignette methodology was utilized to investigate the relationships between leader group prototypicality, identity denial, and three leader outcomes (i.e., charisma, trust, and endorsement). Participants were randomly assigned to one of three experimental conditions: general advocacy (control), ingroup advocacy, and ingroup anti-advocacy. We hypothesized that a Black, male target displaying ingroup advocacy behaviors would be perceived most favorably while a Black, male target displaying ingroup anti-advocacy behaviors would be perceived most poorly. Furthermore, we predicted that identity denial, measured via perceived racial identification, would serve as a mediator. Overall, we found support for our hypotheses, with the exception being that there were no significant differences in leader outcome ratings when comparing the general advocacy condition to the ingroup advocacy condition, even despite the significant mediation throughout all conditions. In summary, Black Americans on average do not expect a Black, male leader to help other Black employees, but he is expected to not devalue or trivialize his Black identity. Doing so would lead to identity denial and less positive evaluations. In contrast, standing in solidarity with the ingroup increases the leader’s perceived racial identification the most and this in turn helps to bolster leader outcomes. Although future research should test climate change as a valid control condition, our pattern of findings suggests that environmental sustainability should be a safe topic for a Black, male leader to advocate for if he wishes to remain more neutral on matters pertaining to race.

description: We formulate a generic concept model for the deformation of a locally disordered, macroscopically homogeneous material which undergoes irreversible strain softening during plastic deformation. We investigate the influence of the degree of microstructural heterogeneity and disorder on the concomitant strain localization process (formation of a macroscopic shear band). It is shown that increased microstructural heterogeneity delays strain localization and leads to an increase of the plastic regime in the macroscopic stress-strain curves. The evolving strain localization patterns are characterized and compared to models of shear band formation published in the literature.

description: Atomically precise superlattices involving transition metal oxides provide a unique opportunity to engineer correlated electron physics using strain (modulated by choice of substate) and quantum confinement (controlled by layer thickness). Here we use the combination of density functional theory and dynamical mean field theory (DFT+DMFT) to study Ni E$_g$ $d$-orbital polarization in strained LaNiO$_3$/LaAlO$_3$ superlattices consisting of four layers of nominally metallic NiO$_2$ and four layers of insulating AlO$_2$ separated by LaO layers. The layer-resolved orbital polarization is calculated as a function of strain and analyzed in terms of structural, quantum confinement, and correlation effects. The effect of strain is determined from the dependence of the results on the Ni-O bond-length ratio and the octahedral rotation angles; quantum confinement is studied by comparison to bulk calculations with similar degrees of strain; correlation effects are inferred by varying interaction parameters within our DFT+DMFT calculations. The calculated dependence of orbital polarization on strain in superlattices is qualitatively consistent with recent X-ray absorption spectroscopy and resonant reflectometry data. However, interesting differences of detail are found between theory and experiment. Under tensile strain, the two inequivalent Ni ions display orbital polarization similar to that calculated for strained bulk LaNiO$_3$ and observed in experiment. Compressive strain produces a larger dependence of orbital polarization on Ni position and even the inner Ni layer exhibits orbital polarization different from that calculated for strained bulk LaNiO$_3$.

description: We present consistent results for molecular conduction using two central-complementary approaches: the non-equilibrium Green's function technique and the quantum master equation method. Our model describes electronic conduction in a donor-acceptor junction in which electron transfer is coupled to nuclear motion, modeled by a harmonic vibrational mode. This primary mode is further coupled to secondary phonon modes, a thermal bath. Assuming weak electron-phonon coupling but arbitrary large molecule-metal hybridization, we compute several non-equilibrium transport quantities: the mean phonon number of the primary mode, charge current statistics. We further present scaling relations for the cumulants valid in the large voltage regime. Our analysis illustrates that the non-equilibrium Green's function technique and the quantum master equation method can be worked out consistently, when taking into account corresponding scattering processes.

description: The measured I-V hysteresis is complicated by the vast array of different materials, lighting sources, and device architectures. In our study, we used the RTOS method, is shown call asymmetrical method, for I-V then the results showed better accuracy by eliminating in real-time the acceptance effect. We also used this method to compare emerging PV cells with the latter cells that exhibited promising power conversion efficiency and no hysteresis behavior under an indoor lighting simulator. In this study, we defined a performance ratio to compare indoor lighting and solar and the results will be shown different performance trends for the different types of PV in indoor/outdoor, which depends on the device. That will be shown what’s the type of PV that has energy harvesting for the indoor lighting measurement system.

description: This paper presents a method to increase the dynamic range of the EL signal for diagnostics of defective areas in PV modules. It applies a computational method for reconstructing a high dynamic range radiance map from a stack of standard dynamic range images at multiple exposure times designed by Debevec and Malik for visible light cameras (RGB). Increasing the precision of the EL signal has two interests: more quantitative information is then available for automatic analysis, and better visual quality is available for visual inspection in case of a small amplitude EL signal, such as acquired in an outdoor daylight setup using lock-in EL. Both are demonstrated via two experiments during which a PV module is electrically biased and imaged at 8 different exposure times with an InGaAs camera: one indoor and one outdoor in daylight. The exposure times are combined to reconstruct an EL image of higher precision. To measure the increased precision, the number of unique pixel values is used: it increases by a factor larger than 2.5 for the indoor case and a factor higher than 100 in the outdoor case. In the outdoor case the improvement towards visual inspection is also clearly apparent.
A survey of ab-initio calculations shows that segregation-induced grain boundary embrittlement is predicted by bond-breaking arguments

description: The segregation of solute atoms to grain boundaries can have a large influence on the mechanical behavior of polycrystals, particularly in metallic alloys. An overview of 400 calculations of solute-induced changes in grain boundary cohesion from 77 separate studies quantitatively demonstrates that the majority of the variation in solute-induced changes in boundary cohesion is explained by simple bond-breaking arguments. This trend is robust to changes in crystal structure and computational methods. The secondary contributions to embrittlement from other mechanisms, such as atomic size effects and charge transfer, are quantified and discussed as well.

description: The most common equivalent electrical circuit of a real solar cell is probably the one-diode model. Throughout the years, numerous research have focused on the extraction of model parameters from measurements done in standard test conditions (STC) with the goal of replicating the current-voltage characteristics (I-V). The equation that describes the I-V characteristics is highly nonlinear, and also an implicit equation. There are many attempts to write an explicit equation, achieving only limited success. This study proposes an explicit Shockley equation for the five-parameter solar cell model. The form of the equation is new, consisting of the ideal Shockley equation and an additive term. The results confirm the feasibility of the proposed approach, indicating a promising way to a simpleexplicit five-parameter solar cell model.
