description: In the present work a simple boundary layer model for the oxygen transport during Cz silicon crystal growth is revisited and extended by introducing classical scaling laws for the thicknesses of the different boundary layers at the crucible wall, at the free melt surface and at the solid-liquid interface. This lumped model is used to calculate the influence of crystal and crucible rotation on the oxygen transport during Cz growth of 100kg heavy silicon crystals with 210mm diameter in a 24” hot zone geometry. The results of this reduced order model are compared to results from sophisticated, coupled 2D-3D, global numerical simulations of the whole Cz puller. It is found that at a first glance the accuracy of the boundary layer model can be sufficient for certain coarse case studies. However, the boundary layer model hits quickly the wall, when a precise analysis of the oxygen transport is required. The root cause is believed to be the complex flow structure, which results from the combination of crystal and crucible rotation in the vicinity of the solid-liquid interface. For an accurate analysis of oxygen transport sophisticated simulations are indispensable.

description: A sequence search method was developed to search regular frequency spacing in delta Scuti stars by visual inspection and algorithmic search. We searched for sequences of quasi-equally spaced frequencies, containing at least four members per sequence, in 90 delta Scuti stars observed by CoRoT. We found an unexpectedly large number of independent series of regular frequency spacing in 77 delta Scuti stars (from 1 to 8 sequences) in the non-asymptotic regime. We introduce the sequence search method presenting the sequences and echelle diagram of CoRoT 102675756 and the structure of the algorithmic search. Four sequences (echelle ridges) were found in the 5-21 d^{-1} region, where the pairs of the sequences are shifted (between 0.5-0.59 d^{-1}) by twice the value of the estimated rotational splitting frequency (0.269 d^{-1}). The general conclusions for the whole sample are also presented in this paper. The statistics of the spacings derived by the sequence search method, by FT and that of the shifts are also compared. In many stars, more than one almost equally valid spacing appeared. The model frequencies of FG Vir and their rotationally split components were used to reveal a possible explanation that one spacing is the large separation, while the other is a sum of the large separation and the rotational frequency. In CoRoT 102675756, the two spacings (2.249 and 1.977 d^{-1}) agree better with the sum of a possible 1.710 d^{-1} large separation and two or one times, respectively, the value of the rotational frequency.

Low Temperature Route for Si Cells

description: 38th European Photovoltaic Solar Energy Conference and Exhibition; 330-333
description: Silicon heterojunction (HJ) solar cell is one of the leading technologies for single junction photovoltaic devices and it could be successfully integrated into a silicon based multijunction solar device, in conjunction with a large band gap cell. To be used as a bottom cell, the HJ device needs to adapt to the current technology for top cells, which are typically far less mature and characterized by smaller areas. However, if the HJ device is cut from a finished larger cell, the original edge passivation gets lost, causing the introduction of surface recombination paths and an overall decrease of the device performance. In this context, the development of a proper edge passivation procedure to be applied to high quality HJ solar cells becomes of major importance. We tried two different strategies of edge passivation based either on wet processes, such as the mesa etching of the device, or plasma treatment of the vertical edges. The latter consisting in the deposition of 1-10 nm of hydrogenated amorphous Si on the edges. In order to characterize the recombination losses and quantify the effect of different passivations, we did current-voltage measurements in light and dark conditions and quasi- steady-state photoconductivity measurements.

description: Il saggio intende analizzare, dal punto di vista narratologico, alcune trasformazioni che interessano i rapporti di dialogicità interni nel genere della confessione tra Settecento e Ottocento. In particolare, si vuole mostrare come il paradigma giudiziario delle Confessions di Rousseau, che ha fra i suoi modelli un genere assai popolare come quello dei mémoires judiciaires e dentro il quale il narratario viene concepito come l’orizzonte per la costruzione di un’etica condivisa, entri in crisi con lo sviluppo della scienza psicologica ottocentesca, quando in autori come Paul Bourget e Gabriele D’Annunzio l’impossibilità di assumere la ragione come fondamento di un’esperienza intersoggettiva invita a ripensare la presenza e l’assenza del lettore nel testo.

description: In this note, analysis of time delay systems using Lambert W function approach is reassessed. A common canonical form of time delay systems is defined. We extended the recent results of [6] for second order into nth order system. The eigenvalues of a time delay system are either real or complex conjugate pairs and therefore, the whole eigenspectrum can be associated with only two real branches of the Lambert W function. A new class of time delay systems is characterized to extend the applicability of the above said method. A state variable transformation is used to transform the proposed class of systems into the common canonical form. Moreover, this approach has been exploited to design a controller which places a subset of eigenvalues at desired locations. Stability is analyesed by the help of Nyquist plot. The approach is validated through an example.

description: One of the most promising approaches to overcome the drastic channel variations of millimeter wave (mmW) communications is to deploy dual-mode base stations that integrate both mmW and microwave (\muW) frequencies. Reaping the benefits of a dual-mode operation requires scheduling mechanisms that can allocate resources efficiently and jointly at both frequency bands. In this paper, a novel resource allocation framework is proposed that exploits users' context, in terms of user application (UA) delay requirements, to maximize the quality-of-service (QoS) of a dual-mode base station. In particular, such a context-aware approach enables the network to dynamically schedule UAs, instead of users, thus providing more precise delay guarantees and a more efficient exploitation of the mmW resources. The scheduling of UAs is formulated as a one-to-many matching problem between UAs and resources and a novel algorithm is proposed to solve it. The proposed algorithm is shown to converge to a two-sided stable matching between UAs and network resources. Simulation results show that the proposed approach outperforms classical CSI-based scheduling in terms of the per UA QoS, yielding up to 36% improvement. The results also show that exploiting mmW resources provides significant traffic offloads reaching up to 43% from \muW band.

description: Completing our investigations on different melt removal techniques presented at previous PVSEC we installed an appliance in our SCU-G1 furnace for pouring the impurity-enriched silicon melt at the top of the ingot at the end of crystallization. With this method any amount of silicon melt between 0 and 25% (compared to the original mass of the G1 ingot) can be removed completely within a few seconds. Thus, the top surface of the growing crystal can be freed from the impurity enriched melt immediately and completely before the end of the regular crystallization process. This can be detected by optical investigation of the ingot’s top surface. However, in all of our experiments a top red-zone of at least 1.7 cm thickness in the mc-Si ingot remained. Compared to reference ingots, where no melt was removed, no significant thickness reduction was achieved. A deeper analysis of the minority charge carrier lifetime by a diffusion model [9] revealed that, typically, the Fei content in the ingot’s top region was reduced by a factor of about 3 compared to reference ingots. Yet, this seems to be not enough to affect the thickness of the top red zone. We suppose additional contamination of the ingot via the gas phase to be a reason for this behavior.

description: Il contributo analizza i rapporti tra retorica di scuola e teatro classico. Attraverso alcuni esempi di esercizi declamatori che, nelle Declamationes minores dello Pseudo-Quintiliano, richiamano, in maniera più o meno evidente, i paradigmi tragici di Oreste e Antigone, si dimostra che il precedente letterario costituisce un fertile terreno di riflessione, pur in un diverso contesto storico e sociale, relativo al rapporto che intercorre tra l’agire morale e quello legale. Anche all’interno di un’aula scolastica che imita la prassi forense, dunque, è possibile trovare testimonianza dell’attualità di un modello mitico, che costringe lo studente a porre in discussione questioni etiche e relative ai rapporti familiari.

Year: 2016

description: A dry port is a recent phenomenon in the Ethiopian logistics history. The Addis Ababa dry port Kaliti branch is among the youngest dry ports established in Ethiopia. It was officially called a dry port in 2014 to facilitate entry and exit of goods from different ports. Customers using the port, however, complain that the port does not deliver an efficient service to its clients. The focus of this paper is to explore issues that could hinder the efficient service delivery. By employing qualitative approaches, the researcher conducted In-depth Interviews with both employees and clients of the dry port. Moreover, site observation was made to explore the current facilities of the dry port and compare it with other dry ports. Customers indicated that, the human resource of the dry port is not equipped with the necessary dry port knowledge as being the dry port a recent phenomenon in Ethiopia there is shortage of professionals who have the knowledge of logistics activities. Most employees get familiar with their current duties by experience and short term trainings given by the organizations. Though the current facility has enough space, there were no adequate offices for both employees and other stakeholders of the organization and warehouse facilities. Most participants agree that not using modern information technologies has not made the dry port as competitive as other dry ports. There was a difference of opinion on the current governance of the dry port between the study participants that few respondents say that being a public enterprise didn't hinder the dry port to operate efficiently but the study revealed that most facilities are not fulfilled by budget constraints and other related management issues of the dry port. Based on the findings, there is a lot to be done on both in infrastructure and human power so that the dry port would be competitive and deliver a quality service to all its customers

description: Tribunali e questioni giuridiche rappresentano luoghi e temi ampiamenti esplorati nel panorama audiovisivo contemporaneo. In particolare, nell’ambito della produzione seriale, il legal drama risulta uno dei generi più diffusi e di maggior successo. In questo paper si è analizzata la struttura narrativa di quattro serie televisive del prime-time statunitense (Boston Legal, Abc 2004-2008; The Good Wife, Cbs 2009-2016; Suits, Usa Network 2011-2019; For the People, Abc 2018-2019) al fine di comprendere in che modo si siano articolati gli elementi caratterizzanti del genere legal: i tribunali, i casi legali e le dinamiche professionali. Attraverso l’individuazione delle linee narrative che definiscono il genere (professional plot, sentimental plot e legal cases plot), si è applicata la metodologia della quantitative content analysis grazie alla quale sono state codificate quasi 300 ore di video che hanno permesso di delineare tre formule narrative: la formula etico-sociale, la formula antologica e la formula status-centrica.

description: L’articolo analizza il motivo della giustizia nel film Oltre la notte (2017) di Fatih Akin. Il film tematizza la ‘giustizia’ su due livelli: uno, il film crea per la prima volta dopo la serie di omicidi commessi dal Nsu in Germania empatia per le vittime e le loro famiglie, rendendo così giustizia alla sofferenza delle vittime, e due, il film mette in scena i conflitti che nascono in un mondo post-metafisico fra la dimensione della giustizia e l’agency del soggetto moderno. Dato che il film è uscito prima dell’esito del processo reale ai membri del Nsu, può anche essere letto, tramite l’uso degli strumenti del campo di studi del Law and Literature, come contributo al tessuto normativo con il quale si valuta l’esito del processo reale.

High Temperature Route for Si Cells

description: 38th European Photovoltaic Solar Energy Conference and Exhibition; 321-325
description: In this work, we investigate the use of localised laser recrystallisation on full-area amorphous silicon layers to enable an approach for local polysilicon contact formation. We show that laser recrystallisation paired with selective etching of amorphous silicon enables localised polysilicon layers with high aspect ratios. We demonstrate that a 32 wt% potassium hydroxide solution is suitable to achieve selective etching on hydrogenated amorphous silicon with a comparatively higher etch rate of about 100 nm per minute while avoiding significant etching of the polysilicon regions, with a vertical etch rate of up to 50 nm per minute on a <100> c-Si surface. We confirm that a 2 nm interfacial oxide can survive laser processing via its FTIR peak at 1079 cm-1 . We propose a cell process using this method to fabricate selective tunnel-oxide polysilicon contacts.

Giustizia della terra, giustizia del cielo. Modelli e ideologie della corruzione nella Bibbia ebraica
Creators: name: D'Amico, Davide
Publisher: name: Griseldaonline
Year: 2023

description: Lo studio indaga il modo in cui il testo biblico affronta il tema della corruzione giudiziaria. Per un sistema normativo che si auto-concepisce come divinamente ispirato, un fenomeno come la corruzione costituisce un particolare problema. Inficiando l’imparzialità del giudizio, il sistema delle tangenti favorisce il ricco a discapito delle classi più povere. L’analisi dei testi letterari che affrontano il tema della corruzione permette di individuare nella Bibbia due diversi orientamenti ideologici. Il primo orientamento è presente perlopiù nelle sezioni legali e, in parte, nelle invettive profetiche e concepisce la corruzione come un problema sociale e giuridico. Il secondo orientamento riguarda i cosiddetti ‘Scritti’, ovvero l’ultima sezione del canone ebraico. In questi testi emerge con forza la tendenza a teologizzare il problema della giustizia legando, di conseguenza, il tema della corruzione a quello del peccato religiosamente inteso.

description: It is well known that the probability distribution function (PDF) of galaxy density contrast is approximately lognormal; whether the PDF of mass fluctuations derived from weak lensing convergence (kappa_WL) is lognormal is less well established. We derive PDFs of the galaxy and projected matter density distributions via the Counts in Cells (CiC) method. We use maps of galaxies and weak lensing convergence produced from the Dark Energy Survey (DES) Science Verification data over 139 deg^2. We test whether the underlying density contrast is well described by a lognormal distribution for the galaxies, the convergence and their joint PDF. We confirm that the galaxy density contrast distribution is well modeled by a lognormal PDF convolved with Poisson noise at angular scales from 10-40 arcmin (corresponding to physical scales of 3-10 Mpc). We note that as kappa_WL is a weighted sum of the mass fluctuations along the line of sight, its PDF is expected to be only approximately lognormal. We find that the kappa_WL distribution is well modeled by a lognormal PDF convolved with Gaussian shape noise at scales between 10 and 20 arcmin, with a best-fit chi^2/DOF of 1.11 compared to 1.84 for a Gaussian model, corresponding to p-values 0.35 and 0.07 respectively, at a scale of 10 arcmin. Above 20 arcmin a simple Gaussian model is sufficient. The joint PDF is also reasonably fitted by a bivariate lognormal. As a consistency check we compare the variances derived from the lognormal modelling with those directly measured via CiC. Our methods are validated against maps from the MICE Grand Challenge N-body simulation.

description: The quantum transport properties of graphene and monolayer $MoS_2$ superconductor heterostructures has been of considerable importance in the recent few years. Layered nature of molybdenum disulfide permits the superconducting correlation induction. Moreover, peculiar dynamical features of monolayer $MoS_2$, such as valence band spin-splitting in the nondegenerate $K$ and $K'$ valleys originated from strong spin-orbit coupling, and considerable direct band gap can make it potentially a useful material for electronics applications. Using the Dirac-like Hamiltonian of $MoS_2$ with taking into account the related mass asymmetry and topological contributions, we investigate the effect of spin-triplet $p$-wave pairing symmetry on the superconducting excitations, resulting in Andreev reflection process and Andreev bound state in the corresponding normal-superconductor (NS) and superconductor-normal-superconductor (SNS) structures, respectively. We study how the resulting subgap conductance and Josephson current are affected by the particular symmetry of order parameter. The signature of $p_x$-wave symmetry is found to decline the subgap superconducting energy excitations and, consequently, slightly suppress the Andreev reflection in the case of $p$-doped S region. The essential dynamical parameters $λ$ and $β$ of $MoS_2$ have significant effect on the both tunneling conductance and Josephson current. Particularly, the considered $p$-wave symmetry in the superconducting bound energies may feature the zero energy states at the interfaces. The critical current oscillations as a function of length of junction are obtained in the $p$-doped S region.

description: Copper plating metallization is growing in importance to replace silver and to enable growth of photovoltaic to terawatt-scale. Besides better performance of the plated Cu contacts on solar cells, the processing needs to be less complex and more cost effective. The „NOBLE“ metallization responds to cost savings for bifacial silicon heterojunction solar cells. This study shows that the processing with inkjet-printing for patterning of the top Al masking layer is yet mature enough for first tests on industrial pilot. Efficiencies comparable to the Ag screen-printed reference on the same precursors grade are reached. To even improve the patterning throughput a selective laser ablation patterning of the Al/AlOx layer is further investigated. There, laser-induced damaging is avoided by choosing adapted laser settings and first large area SHJ solar cells are manufactured with this method yielding an encouraging 21.4% efficiency.

description: Employing the coset approach we construct component actions for a superparticle moving in AdS$_3$ with $N{=}(2,0)$, $D{=}3$ supersymmetry partially broken to $N{=}2$, $d{=}1$. These actions may contain higher time-derivative terms, which are chosen to possess the same (super)symmetries as the free superparticle. In terms of the nonlinear-realization superfields, the component actions always take a simpler form when written in terms of covariant Cartan forms. We also consider in detail the reduction to the nonrelativistic case and construct the corresponding action a Newton-Hooke superparticle and its higher-derivative generalizations. The structure of these higher time-derivative generalizations is completely fixed by invariance under the supersymmetric Newton-Hooke algebra extended by two central charges.

description: In Ethiopia, one of the social problems that need immediate attention to be addressed with, concerned development sectors and the society as a whole is, physiological, psychological and social problems of Orphan and Vulnerable Children. Even though, there are number of charitable organizations those who are working on wellbeing of OVC in Ethiopia, there is a gap in holistic service provision in relation with solving the problem of OVC. Therefore, the aim of this study is to explore if social innovation approaches can address problem of OVCs. A qualitative research was conducted on selected five charitable organizations, to assess the reason for not hit the problem of OVC. The supports being offered by the non-governmental organizations were insufficient, duplicated and limited to few children in terms of their coverage. There are no coordinated and collaborative approaches utilized among charitable organization to alleviate poverty. Consequently, a number of OVC are still in a difficult situation and seek immediate attention. Thus, strengthening families'/caregivers economic capacity through income generating activities, social and emotional inclusive support programs, inter-organizational coordination, mobilizing resources with in community, study on new approach and try to enforce NGOs to operate new study based profit making approach for wellbeing of orphans and vulnerable children.

High Temperature Route for Si Cells

description: The European SolarEraNet project HEAVENLY has the goal to jointly develop simultaneously contacting novel silver pastes and chemical vapor deposited (CVD) layers which are used for both, surface passivation and formation of emitter and back surface field regions. Within the project, pastes have been produced that contact n + and p+ doped regions simultaneously over a wide f iring-temperature range, achieving contact resistivities below 0.01 mΩcm2 on a 100 Ω/sq n+ emitter. The doped regions are formed by using the high -throughput, cost efficient atmospheric pressure chemical vapor deposition (APCVD) technique which enables the single-sided deposition of doped glass layers, to allow for an efficient co -diffusion step for the formation of both, emitter and back surface field regions. The glass layers remain on the wafer surface after the diffusion process, providing very good sur face passivation (Seff ≤ 2.5 cms-1) and also supporting the contact formation during the subsequent firing process of the Ag pastes. As pastes and passivation layers are developed together, the production of high -efficiency low-cost PERT (Passivated Emitter and Rear Totally diffused) and IBC (interdigitated back contact) solar cells can benefit in three ways from the project’s results: by low contact resistivities, high quality surface passivation, and an efficient processing sequence.

description: he purpose of this research is to assess the challenges and prospects of outsourcing the non- core activities in commercial bank of Ethiopia. The study areas were CBE branches under east Addis district and the outsourcing administrative office. The research is a descriptive study applying both quantitative and qualitative approach in which questioner was collected across a population through simple random sampling and uses descriptive statistics for the data analysis. The finding of the study shows that outsourced service assist commercial bank of Ethiopia to focus more on core functions and strategic areas, to save management time and expand its branch assertively. On the other side, difficult to measure service quality, low employee belongingness and loss of control were the major challenges of the bank due to outsourcing. Finally based on the finding, the researcher recommended that monitoring and evaluation system need to be put in place for timely corrective action before time elapses and rectification becomes so difficult.

description: Passivating contacts based on SiOx/poly-Si enable very high solar cell conversion efficiencies. In this paper, we investigate and optimize the plasma-enhanced chemical vapor deposition (PECVD) of SiOxNy/n-a-Si stacks, their subsequent annealing to SiOxNy/n-poly-Si stacks followed by PECVD SiNx deposition and firing. Whereas the J0 of thermal SiOx/n-poly-Si stacks degrade after firing, PECVD SiOxNy/n-poly-Si stacks exhibit an excellent firing stability with J0 values down to 1.3 fA/cm² after firing which corresponds to an outstanding implied VOC of 744 mV. The application of different hydrogenation processes to the thermal SiOx/n-poly-Si and PECVD SiOxNy/n-poly-Si layers reveals, that both stacks achieve excellent passivation properties with J0 = 1.5 fA/cm² after maximum hydrogenation. However, only the PECVD SiOxNy/n-poly-Si stack maintains this excellent surface passivation after firing possibly due to a superior capability to retain the hydrogen at the c-Si/SiOxNy interface during firing, and thus demonstrates the potential as a future manufacturing process sequence.

description: We investigate the properties of certain elliptic systems leading, a~priori, to solutions that belong to the space of Radon measures. We show that if the problem is equipped with a so-called asymptotic Uhlenbeck structure, then the solution can in fact be understood as a standard weak solution, with one proviso: analogously as in the case of minimal surface equations, the attainment of the boundary value is penalized by a measure supported on (a subset of) the boundary, which, for the class of problems under consideration here, is the part of the boundary where a Neumann boundary condition is imposed.

High Temperature Route for Si Cells

description: 38th European Photovoltaic Solar Energy Conference and Exhibition; 311-316
description: We study the UV stability of lightly doped n- type Si surfaces with a sheet resistance of 154 Ohm/sq, 935 Ohm/sq and 1480 Ohm/sq. These surfaces are passivated by a layer stack consisting of thermal SiO2 and PECVD SiNx and the resulting J0 is in the range of 10 to 40 fA/cm2. We applied these lightly diffused surfaces for the FSFs of IBC cells, and for symmetric n+/n/n+ lifetime samples. We found out that although the 6-inch IBC cells with lighter doped FSFslead to better Voc, they showed more degradation after the UV exposure test (dose of 45 kWh/m2, equivalent to three times of IEC test). The degradation is likely caused by the increase of front surface recombination. Lastly, we summarize several UV degradation test results for both p- and n-type surfaces, based on which it seems that it is advisable to check the UV stability for not only the IBC cells but also other cell concepts which have a lightly doped or even undoped front surface.

description: The r largest order statistics approach is widely used in extreme value analysis because it may use more information from the data than just the block maxima. In practice, the choice of r is critical. If r is too large, bias can occur; if too small, the variance of the estimator can be high. The limiting distribution of the r largest order statistics, denoted by GEVr, extends that of the block maxima. Two specification tests are proposed to select r sequentially. The first is a score test for the GEVr distribution. Due to the special characteristics of the GEVr distribution, the classical chi-square asymptotics cannot be used. The simplest approach is to use the parametric bootstrap, which is straightforward to implement but computationally expensive. An alternative fast weighted bootstrap or multiplier procedure is developed for computational efficiency. The second test uses the difference in estimated entropy between the GEVr and GEV(r-1) models, applied to the r largest order statistics and the r-1 largest order statistics, respectively. The asymptotic distribution of the difference statistic is derived. In a large scale simulation study, both tests held their size and had substantial power to detect various misspecification schemes. A new approach to address the issue of multiple, sequential hypotheses testing is adapted to this setting to control the false discovery rate or familywise error rate. The utility of the procedures is demonstrated with extreme sea level and precipitation data.

description: Ultimately, the magnitude of the energetic particle (EP) forcing signal in the stratosphere may be equivalent to that arising from solar irradiance variations, in particular ultraviolet (UV; Seppälä & Clilverd, 2014). In order to determine whether signals correlating with solar variability are driven by the Sun or dominated by internal variability, we aim to disentangle the two main solar drivers that vary on this quasi-decadal timescale. There are similar concerns due to potential aliasing as reported before (Kuchar et al, 2017). To quantify the relative importance of 11-year SC in terms of UV, EP, and solar proton effects, we use state‐of‐the‐art methods for determining the relative importance of correlated attributes (Bi, 2012), e.g. Lindeman-Gold-Merenda measure (Lindeman et al., 1980) through multiple linear regression. The interpretation of this kind of explanatory approach may shed light on causal structures as well. Finally, new emerging techniques such as the Bayesian approach and explainable AI of nonlinear interactions (Kuchar et al, 2015) will be discussed.

description: We present a reconstruction of the spectral solar irradiance since 1700 using the SATIRE-T2 (Spectral And Total Irradiance REconstructions for the Telescope era version 2) model. This model uses as input magnetograms simulated with a surface flux transport model fed with semi-synthetic records of emerging sunspot groups. We used statistical relationships between the properties of sunspot group emergence, such as the latitude, area, and tilt angle, and the sunspot cycle strength and phase to produce semi-synthetic sunspot group records starting in the year 1700. The semisynthetic records are fed into a surface flux transport model to obtain daily simulated magnetograms that map the distribution of the magnetic flux in active regions (sunspots and faculae) and their decay products on the solar surface. The magnetic flux emerging in ephemeral regions is accounted for separately based on the concept of extended cycles whose length and amplitude are linked to those of the sunspot cycles through the sunspot number. The magnetic flux in each surface component (sunspots, faculae and network, and ephemeral regions) was used to compute the spectral and total solar irradiance between the years 1700 and 2009. This reconstruction is aimed at timescales of months or longer although the model returns daily values. We found that SATIRE-T2, besides reproducing other relevant observations such as the total magnetic flux, reconstructs the total solar irradiance (TSI) on timescales of months or longer in good agreement with the PMOD composite of observations, as well as with the reconstruction starting in 1878 based on the RGO-SOON data. The model predicts an increase in the TSI of 1.2[+0.2, -0.3] Wm-2 between 1700 and the present. The spectral irradiance reconstruction is in good agreement with the UARS/SUSIM measurements as well as the Lyman-alpha composite.

In this work, We design the different solar cell to see the LETID phenomenon, one is using with/without Gallium doped solar cell, another is using 4 different fabricated process by different companies. Using the Gallium doped solar cell reveals an antiresistance for LETID, but form another result show that it still influenced by fabricated process.
