description: In this paper, we report ENN’s results in R&D and mass production of high efficiency silicon
heterojunction solar cells. Using large-size industrial equipment and mass production compatible processes, ENN has
developed hybrid silicon technology (HST) and achieved 23.4% heterojunction solar cell efficiency. We have
successfully developed a low-cost approach to mass production, i.e., converting existing Gen8.5 (5.7m2) thin film solar
line to high efficiency HST fab by upgrading and modification of key equipment and line automation. We have achieved
average cell efficiency of 21.6% in pilot production and demonstrated 317 Wp power output using standard 60-cell (156
mm) modules. ENN’s unique technology route to mass production of high efficiency heterojunction solar cells has
comprehensive competition advantages such as low capital cost, high production capacity, proven equipment
performance & reliability, and fast ramp-up, etc. This provides a viable path for more manufacturers to penetrate into this
area, quickly commercialize low-cost heterojunction technology, and further increase its competitiveness.

description: We assess the accuracy of finite-temperature mean-field theory using as a standard the Hamiltonian and model space of the shell model Monte Carlo calculations. Two examples are considered: the nucleus $^{162}$Dy, representing a heavy deformed nucleus, and $^{148}$Sm, representing a nearby heavy spherical nucleus with strong pairing correlations. The errors inherent in the finite-temperature Hartree-Fock and Hartree-Fock-Bogoliubov approximations are analyzed by comparing the entropies of the grand canonical and canonical ensembles, as well as the level density at the neutron resonance threshold, with shell model Monte Carlo (SMMC) calculations, which are accurate up to well-controlled statistical errors. The main weak points in the mean-field treatments are seen to be: (i) the extraction of number-projected densities from the grand canonical ensembles, and (ii) the symmetry breaking by deformation or by the pairing condensate. In the absence of a pairing condensate, we confirm that the usual saddle-point approximation to extract the number-projected densities is not a significant source of error compared to other errors inherent to the mean-field theory. We also present an alternative formulation of the saddle-point approximation that makes direct use of an approximate particle-number projection and avoids computing the usual three-dimensional Jacobian of the saddle-point integration. We find that the pairing condensate is less amenable to approximate particle-number projection methods due to the explicit violation of particle-number conservation in the pairing condensate. Nevertheless, the Hartree-Fock-Bogoliubov theory is accurate to less than one unit of entropy for $^{148}$Sm at the neutron threshold energy, which is above the pairing phase transition.

description: Passivated Emitter and Rear Cells (PERC) are currently being introduced into mass-production. The conversion efficiency of industrial p-type PERC cells is limited by the emitter saturation current density of around 90 fA/cm2 of conventional homogeneously POCl3 diffused emitters. In this paper we investigate two alternative emitter formation technologies. The first approach named in-situ oxidation inserts a short thermal oxidation in-between the phosphorus silicate glass deposition and the drive-in of a conventional homogeneous POCl3 diffusion thereby reducing the phosphorus surface concentration. The second approach named Gas Phase Etch Back (GEB) selectively removes around 40 nm of the highly doped surface of the POCl3 diffused emitter by the reactive gas phase of the wet chemical rear polishing bath. Whereas the conventional POCl3 emitter exhibits a phosphorus surface doping concentration of 3×1020 cm-3, the in-situ oxidation and the GEB process reduce the doping concentration to 7×1019 cm-3 and 4×1019 cm-3, respectively. Accordingly, the emitter saturation current density is reduced to values of 22 fA/cm2 (in-situ oxidation) and 28 fA/cm2 (GEB). This compares with 89 fA/cm2 for the reference POCl3 diffusion. Whereas the reference POCl3 emitter limits the PERC conversion efficiency  to 21.1% and the open circuit voltage Voc to 655 mV, the in-situ oxidation improves the PERC IV parameters up to 21.5% and 669 mV. The highest efficiency of 21.6% is obtained with the selective GEB emitter. When solving series resistance issues with the most advanced GEB emitter, the measured Voc and Jsc values allow for PERC conversion efficiencies of up to 21.9%.

description: Passivated Emitter and Rear Contact (PERC) is gaining acceptance in solar cell manufacturing due to its
potential for high efficiency for p-type wafers and easy integration into existing lines. For p-type mono
solar cells, the cell efficiency gain arrives 0.6~1.0%, while for multi solar cell is 0.5~0.8%, which is very
attractive to the industry. We report the batch cell efficiency of 19.0% for multi PERC, and 20.70% for
mono PERC solar cells in pilot run.
As for PERC mass production, the effective and reliable AlOx deposition tool is the most important issue
we have to consider. Nowadays, ALD and inline PECVD AlOx tools are the only two choices in the market.
Here we compare the passivation effect and cell efficiency of both tools, to find little difference, but the
former seems a little bit better. High-deposition rate PECVD AlOx shows the advantage of higher
throughput and uptime, which is more acceptable by customers.
Boron-oxygen complex is the origin of the light induced degradation (LID) of the solar cells. LID is the cell
efficiency bottleneck because of the bulk recombination even if the silicon surface is well passivated. In
this paper, we report the LID regeneration evaluation test by thermal and light illumination. Cell level
tests reveal the relative degradation is around 2.0% for mono-PERC and 1.1% for mc-PERC, by means of
LID regeneration, which is acceptable.
The combination of cell efficiency, AlOx tool choice and LID regeneration gives a direction to
industrialization the PERC technology.

description: Commonly, a two-dimensional topological insulator is characterized by non-zero Chern numbers associated with its band structure. In our work, we present the experimental demonstration of an anomalous topological insulator, for which the Chern numbers are always zero, and the winding number is the appropriate quantity describing the topological character of the system. We probe the robustness of the chiral edge states in such anomalous topological insulators and analyze the phase transition between topological and trivial phase.

description: Alzheimer’s disease (AD) is one of the most common causes of neurodegenerative dementia affecting more than 50 million people worldwide each year. Emerging evidence suggests that alterations in gut microbiota composition can impact AD pathology and may contribute to cognitive impairment. AD is associated with key pathologies such as depositions of neurotoxic amyloid-beta plaques, neurofibrillary tangles formed by hyperphosphorylation of Tau proteins, and neuroinflammation. Recent studies have found that alterations in gut microbiota via a bidirectional pathway known as the gut microbiome-brain axis can also impact neuroinflammation. Neuroinflammation in the brain, mediated by astrocytes and microglial cells, is elevated in AD. To understand the effects of the gut microbiota on the gut microbiome-axis and AD pathologies, we evaluated the gene expression levels of six proinflammatory cytokines: IL12𝛽, VIM, ARG1, and GFAP in triple transgenic (3x-Tg-AD) mice and their wildtype genetic backgrounds (controls). The gut microbiota of these mice had previously been characterized. We hypothesized that 3x-Tg-AD mice would have higher levels of gene expression for both proinflammatory and anti-inflammatory cytokines after 52 weeks of age. Quantitative reverse transcription PCR (RT-qPCR) was performed on colon and hippocampus tissue samples collected post-mortem at 8, 24, and 52 weeks of age. We found that gene expression levels of IL12𝛽, VIM, and GFAP were significantly different after 52 weeks of age in 3x-Tg-AD mice as compared to their wildtype (p < 0.05, Mann Whitney). Integrated analysis with gut microbiome diversity may determine if neuroinflammation is influenced by alterations in the gut microbiota.

description: Layer transfer process based on a porous silicon template is one of the promising replacements for the conventional wafer sawing technologies. For the process to be cost-effective, one challenge is the multiple recycling of the Si substrate used as a template for epitaxial growth. The Si substrate after detachment has different types of defects. Therefore, reusing the substrate without surface reconditioning induces low detachment yields and generates low quality epitaxial Si-foils. The current work presents the first steps taken into the realization of successful substrate re-use. Firstly, possible defects and undesirable features on the surface after the detachment process are identified. Secondly, a wet-chemical reconditioning process is developed. Finally, the effectiveness of this reconditioning process is evaluated by monitoring the evolution of the foil quality through different generations. Until now, 5 generations of epitaxial foils have been demonstrated at imec.

description: In this work we are aiming at the goal of fabricating a cost-effective HIP-MWT module exceeding 300W. In order to accomplish this goal HIP-MWT (high-performance metal wrap through) silicon solar cells [1, 2] are fabricated on industrial PERC (passivated emitter and rear cell) precursors. Simulation of the optimal metallization layout for MWT based on measured parameters show cell efficiencies up to 21.5%. The consequentially fabricated HIP-MWT solar cells reach maximum efficiencies of 21.4%. The in parallel processed H-pattern reference cells reach maximum efficiencies of 21.2%. The cell efficiencies show a reduced advantage for MWT than in similar experiments, which is due to the tapered busbars of the reference cells allowing nearly the same short circuit currents. Anyhow, combined with a module interconnection based on back contact foils a cell-to-module (CTM) loss of 2 % is demonstrated which allows module power over 300 WP. Due to a power advantage of about 15W in comparison to H-pattern modules the cost of ownership calculation shows a cost advantage of the HIP-MWT module of 3.2 %. Simulation, experimental results and cost calculation show an advantage for HIP-MWT technology over the H-pattern reference leading to the conclusion that MWT is a more cost-effective concept.

description: Optical lattice clocks are at the forefront of frequency metrology. Both the instability and systematic uncertainty of these clocks have been reported to be two orders of magnitude smaller than the best microwave clocks. For this reason, a redefinition of the SI second based on optical clocks seems possible in the near future. However, the operation of optical lattice clocks has not yet reached the reliability that microwave clocks have achieved so far. In this paper, we report on the operation of a strontium optical lattice clock that spans several weeks, with more than 80% uptime. We make use of this long integration time to demonstrate a reproducible measurement of frequency ratios between the strontium clock transition and microwave Cs primary and Rb secondary frequency standards.

description: We investigate the impact of high-temperature processes on phosphorus-doped n-type Czochralski-grown silicon (Cz-Si) wafers. Wafers from five ingots are subjected to high-temperature process sequences with different temperatures, times, and gas atmospheres. The process sequences are specifically chosen to represent different routes for the fabrication of high-efficiency n-type Cz-Si solar cells. As POCl3 diffusion is known for its effective gettering of metal impurities, it is preferably used as the last high-temperature step. However, our results show that other process sequences, e.g. with BBr3 diffusion as last high-temperature step, enable high charge carrier lifetimes in the range of a few milliseconds as well. For some materials and process sequences, ring-shaped defect structures are observed while for others increased charge carrier lifetimes by a factor up to 2.6 are found compared to their initial values prior to high temperature processing.

description: Controlling ultrafast material transformations with atomic precision is essential for future nanotechnology. Pulsed laser annealing (LA), inducing extremely rapid and localized phase transitions, is a powerful way to achieve this, but it requires careful optimization together with the appropriate system design. We present a multiscale LA computational framework able to simulate atom-by-atom the highly out-of-equilibrium kinetics of a material as it interacts with the laser, including effects of structural disorder. By seamlessly coupling a macroscale continuum solver to a nanoscale super-lattice Kinetic Monte Carlo code, this method overcomes the limits of state-of-the-art continuum-based tools. We exploit it to investigate nontrivial changes in composition, morphology and quality of laser-annealed SiGe alloys. Validations against experiments and phase-field simulations, as well as advanced applications to strained, defected, nanostructured and confined SiGe are presented, highlighting the importance of a multiscale atomistic-continuum approach. Current applicability and potential generalization routes are finally discussed.

description: The Ch-type asteroid (130) Elektra is orbited by three moons, making it the first quadruple system in the main asteroid belt. We aim to characterise the irregular shape of Elektra and construct a complete orbital model of its unique moon system. We applied the All-Data Asteroid Modelling (ADAM) algorithm to 60 light curves of Elektra, including our new measurements, 46 adaptive-optics (AO) images obtained by the VLT/SPHERE and Keck/Nirc2 instruments, and two stellar occultation profiles. For the orbital model, we used an advanced $N$-body integrator, which includes a multipole expansion of the central body (with terms up to the order $\ell = 6$), mutual perturbations, internal tides, as well as the external tide of the Sun acting on the orbits. We fitted the astrometry measured with respect to the central body and also relatively, with respect to the moons themselves. We obtained a revised shape model of Elektra with the volume-equivalent diameter $(201\pm 2)\,{\rm km}$. Out of two pole solutions, $(λ, β) = (189; -88)\,{\rm deg}$ is preferred, because the other one leads to an incorrect orbital evolution of the moons. We also identified the true orbital period of the third moon S/2014 (130) 2 as $P_2 = (1.642112 \pm 0.000400)\,{\rm d}$, which is in between the other periods, $P_1 \simeq 1.212\,{\rm d}$, $P_3 \simeq 5.300\,{\rm d}$, of S/2014 (130) 1 and S/2003 (130) 1, respectively. The resulting mass of Elektra, $(6.606 \substack{+0.007 \\ -0.013}) \times 10^{18}\,{\rm kg}$, is precisely constrained by all three orbits. Its bulk density is then $(1.536 \pm 0.038)\,{\rm g\,cm}^{-3}$. The expansion with the assumption of homogeneous interior leads to the oblateness $J_2 = -C_{20} \simeq 0.16$. However, the best-fit precession rates indicate a slightly higher value, ${\simeq}\,0.18$.

description: We present building blocks for double-side contacted cells with poly-Si on passivating interfacial oxides (POLO) junctions for both polarities, fabricated by a lean process flow. For this purpose, we evaluate p+ and n+ POLO junctions utilizing ~1.7 nm thin wet chemically grown (ozone diluted in di-ionized water) and ozone grown interfacial oxides on different surface morphologies. We achieve excellent passivation quality on damaged etched (100) surfaces with record low J0 values of 0.6 fA/cm2 (implied open circuit voltage Voc,impl 748 mV) for n+ POLO junctions and of 5 fA/cm2 (Voc,impl 729 mV) for p+ POLO junctions. However, on alkaline textured surfaces, ~6 times higher J0 values are obtained. We compare ex-situ-doped poly-Si (intrinsically deposited and subsequently ion implanted) with in-situ-doped poly-Si layers. For POLO junctions formed on textured surfaces by utilizing wet chemical oxides and low-pressure chemical vapor deposition (LP-CVD) of 20 nm in-situ n+-doped poly-Si, we obtain J0 values down to 2.4 fA/cm2. Also with plasma-enhanced chemical vapor deposition (PE-CVD) of in-situ-doped amorphous Si and subsequent crystallization, we obtain comparable results. A transparent conductive oxide (TCO), preferably temperature stable, seems to be required to support the limited lateral conductivity of POLO junctions with poly-Si layer thicknesses ≤ 20 nm. We find that the conductivity of indium tin oxide (ITO) strongly decreases upon firing, while the initial conductivity can be maintained even for firing temperatures of 800°C when capping the ITO with a thin SiNx layer. Our recent cell precursors (156 mm  156 mm Cz n-type wafers with an n+ POLO junction on an alkaline textured front-side and a p+ POLO junction on a damage-etched rear-side) exhibit a promising Voc,impl value of 732 mV, and a total J0 value of the doped surfaces of 12 fA/cm2. In combination with the high pseudo fill factor of 85.3 % and with a short-circuit current density of 40 mA/cm2 as calculated by ray tracing simulations, the corresponding pseudo efficiency is 25.0 %.

description: We report on radio timing and multiwavelength observations of the 4.66 ms redback pulsar J1048+2339, which was discovered in an Arecibo search targeting the Fermi-LAT source 3FGLJ1048.6+2338. Two years of timing allowed us to derive precise astrometric and orbital parameters for the pulsar. PSR J1048+2339 is in a 6-hour binary, and exhibits radio eclipses over half the orbital period and rapid orbital period variations. The companion has a minimum mass of 0.3 solar masses, and we have identified a $V \sim 20$ variable optical counterpart in data from several surveys. The phasing of its $\sim 1$~mag modulation at the orbital period suggests highly efficient and asymmetric heating by the pulsar wind, which may be due to an intrabinary shock that is distorted near the companion, or to the companion's magnetic field channeling the pulsar wind to specific locations on its surface. We also present gamma-ray spectral analysis of the source and preliminary results from searches for gamma-ray pulsations using the radio ephemeris.

description: Gyrochronology, the empirical relation between rotation and age, can provide important leverage on important astrophysical questions ranging from basic stellar evolution models, to the timescale for the development of habitable planets, to the structural and chemical history of the Galaxy. Key to gyrochronology’s usefulness is the determination of reliable rotation rates. We present the rotational characteristics of a sample of several thousand main sequence pairs observed by NASA’s Transiting Earth Survey Satellite (TESS) and the Kepler K2 extended missions. Essentially open clusters with only two components, such pairs may help break the degeneracies in the rotation-activity-metallicity vs. age relations for main sequence stars.

description: The recently proposed theoretical concept of a Hund's metal is regarded as a key to explain the exotic magnetic and electronic behavior occuring in the strongly correlated electron systems of multiorbital metallic materials. However, a tuning of the abundance of parameters, that determine these systems, is experimentally challenging. Here, we investigate the smallest possible realization of a Hund's metal, a Hund's impurity, realized by a single magnetic impurity strongly hybridized to a metallic substrate. We experimentally control all relevant parameters including magnetic anisotropy and hybridization by hydrogenation with the tip of a scanning tunneling microscope and thereby tune it through a regime from emergent magnetic moments into a multi-orbital Kondo state. Our comparison of the measured temperature and magnetic field dependent spectral functions to advanced many-body theories will give relevant input for their application to non-Fermi liquid transport, complex magnetic order, or unconventional superconductivity.

description: Diamond wire-saw is widely using in single-crystalline silicon wafer slicing process. The vantages of
diamond wire technology are low cost and high production speed. However, the diamond-wire saw is not applied on
multi-crystalline wafer slicing process. The reason is the saw mark on the surface of multi-crystalline wafer caused
by slicing will affect the texturing process. Therefore, a surface treatment for the diamond wire sawn multicrystalline
wafer is necessary. In this study, the grinding and sandblasting process was used for surface treatment of
diamond wire sawn multi-crystalline wafer. The wafer quality and the solar cell efficiency were used to evaluate the
effect of surface treatment process. The experimental results reveal significantly improved the energy conversion
efficiency. With surface treatment process, the saw mark on the wafer surface could be removed. The reforming
surface can have better texturing structure and enhance the solar cell characteristics. The energy conversion
efficiency is 18.4% with surface treatment, which is comparable with the slurry sawn solar cell (18.3%). The cost of
the surface treatment is lower than the traditional slurry wire technology.

description: Formamide (NH$_2$CHO) has previously been detected in several star-forming regions and is thought to be a precursor for different prebiotic molecules. Its formation mechanism is still debated, however. Observations of formamide, related species and their isopotologues may provide useful clues to the chemical pathways leading to their formation. The Protostellar Interferometric Line Survey (PILS) represents an unbiased high angular resolution and sensitivity spectral survey of the low-mass protostellar binary IRAS 16293-2422 with the Atacama Large Millimeter/submillimeter Array (ALMA). We detect for the first time the three singly deuterated forms of NH$_2$CHO (NH$_2$CDO, cis- and trans-NHDCHO) as well as DNCO towards the component B of this binary source. The images reveal that the different isotopologues are all present in the same region. Based on observations of the $^{13}$C isotopologues of formamide and a standard $^{12}$C/$^{13}$C ratio, the deuterium fractionation is found to be similar for the three different forms with a value of about 2%. The DNCO/HNCO ratio is also comparable to the D/H ratio of formamide ($\sim$1%). These results are in agreement with the hypothesis that NH$_2$CHO and HNCO are chemically related through grain surface formation.

Silicon Solar Cells Improvements and Innovation

description: In imec’s i2-module concept, silicon heterojunction interdigitated back-contacted (SHJ-IBC) solar cells are fabricated on monocrystalline foils bonded to glass. The proposed technology allows for cell processing on thin wafers mechanically supported by the glass, increasing the yield of processing such thin wafers. A process sequence for SHJ-IBC cell fabrication that can be applied to bonded thin foils is described. We investigated and optimized individual process steps on thick wafers. Then the developed steps were integrated into a process flow to fabricate solar cells on wafers with different thicknesses and bonding agents. On wafers with a thickness of 190 μm, functional cells with efficiencies of 22.6% and 21.7% were made on freestanding and silicone bonded wafers, respectively. On thin wafers of 57 μm, our best SHJ-IBC cell on an EVA bonded wafer exhibits excellent Voc of 740 mV and efficiency of 20.0%, which demonstrates the high potential of the i2-module concept.

description: The placebo effect is a fascinating phenomenon that has advanced beyond the medical field into the field of sport and exercise psychology. Preliminary evidence suggests the importance of expectations on the effects of exercise, but the current literature is lacking a strong expectation manipulation and the investigation of cognitive benefits following exercise. To address this gap, 77 young adults (Mage= 29.84, SD = 9.83) were asked to rate the expected cognitive, psychological, and physical benefits of a stretching program, and to elaborate on their ratings via an online survey. Participants were randomly allocated to three expectation conditions: expectation-benefit, expectation-no benefit, or no expectation control. All participants were evaluating the same stretching program, but read fictitious testimonies and watched videos that were aimed at manipulating their expectations. Analyses revealed that the expectation-benefit group expected higher cognitive benefits from the stretching program than the expectation-no benefits group (p= .01). No significant differences emerged on the expectation to receive psychological well-being or physical benefits across all three groups. The thematic analysis of participants’ rationale for their ratings revealed that beliefs about benefits were modified through the testimonies and videos provided to them. Participants also relied on their previous knowledge or experience about stretching to inform their predictions about the expected benefits of the stretching program. Results from this study expand the knowledge on expectations manipulation in exercise settings, and provide exercise professionals with strategies to maximize the benefits participants can receive from exercise.
On the Parameters That Impact the Performance of Diamond Wire in the Production of Silicon Wafers

description: During the production of silicon wafers with diamond wire the wire is moved regularly back and forth with a small fresh wire supply. As a consequence diamond wire is used very intensively and passes several times the wire web, contrary to the single pass during the slurry-based process with unidirectional wire movement. This results in a nonuniform wear and subsequently performance reduction of the diamond wire along the wire web that becomes visible in a complex wire bow behavior. Particularly designed diamond wire cuts and measurements of wire bow reveal that besides the uniformly increasing wire abrasion due to sawing of silicon, the wire is additionally damaged during the first contact with silicon, the winding on and off the wire spools and the sawing of beam material. It is shown that different diamond wires are more or less sensitive to damage during the first contact with silicon and that different beam materials result in more or less wire wear. At last, a cut without winding the wire on and off the wire spools suggests that a stable wire tension force has a major impact on diamond wire performance.

description: To reduce the amount of silicon used and increase the efficiency achievable by photovoltaic wafers, manufacturers have pursued methods of reducing wafer thickness. While wire sawing can be used to produce wafers thinner than the standard 180-200 micron thickness, these thin wafers have reduced mechanical integrity and break during cell fabrication, electrical interconnection and encapsulation in modules. As such, standard industry wafer thickness has remained between 180-200 microns. 1366 Technologies’ Direct Wafer® process can meet the industry’s anticipated need for thinner wafers without compromising wafer strength. The process, which forms a wafer directly from molten silicon, has certain advantages over wire-sawn wafers, including the ability to locally-control wafer thickness. This local control can create a thick border where the perimeter of each wafer is of greater thickness than the remainder of the wafer, resulting in a strong, thin wafer able to withstand typical manufacturing stresses. This elegant solution can be delivered at a cost below

description: We demonstrate a source of correlated photon pairs which will have applications in future integrated quantum photonic circuits. The source utilizes spontaneous four-wave mixing (SFWM) in a dispersion-engineered nanowaveguide made of AlGaAs, which has merits of negligible two-photon absorption and low spontaneous Raman scattering (SpRS). We observe a coincidence-to-accidental (CAR) ratio up to 177, mainly limited by propagation losses. Experimental results agree well with theoretical predictions of the SFWM photon pair generation and the SpRS noise photon generation. We also study the effects from the SpRS, propagation losses, and waveguide lengths on the quality of our source.
