Nowadays, a stack of heavily doped polysilicon ( poly ‐Si) and tunnel oxide (SiO x ) is widely employed to improve the passivation performance in n ‐type passivated contact (TOPCon) silicon solar cells. In this case, it critical develop an in‐line advanced fabrication process capable producing high‐quality SiO . Herein, ozone‐gas oxidation (OGO) prepare proposed be applied TOPCon cell fabrication, which has obtained better compared with previously reported plasma‐assisted N 2 O (PANO)...
We put forward the existence of localized necklace solitons and ring in a defocusing cubic nonlinear medium with an imprinted Bessel optical lattice. Novel families are found their unique properties, including multistable states revealed. show that both could reside on any lattices. They dynamically stable provided lattice is modulated deep enough. The uncovered phenomena may open new way for soliton control manipulation.
During the fabrication process of erbium (Er)-doped Si-based light-emitting devices (LEDs), it is well known that high-temperature annealing necessary for activation Er3+ ions and its diffusion in dielectric layer inevitable this process. However, whether will contaminate interface deteriorate device during postanneal remains unclear. This work sheds light on detailed electrical properties between silicon oxynitride (SiNxOy) crystal (c-Si) before after Er doping. We found activated bring...
The influence on electrical characteristics of interface states by using nitrogen (N) and phosphorus (P) co-doped polysilicon (poly-Si) in tunnel oxide passivation contact silicon solar cells has been investigated. We find that the introduction N co-doping P heavily doped poly-Si decreases its own work function; thus, built-in potential (n+)/tunnel SiOx/c-Si (p) junction is notably enhanced. at have investigated current/capacitance–voltage deconvolution. measured results suggest state...
We introduced a kind of novel perfect optical vortex beam, which we termed herein as helical Mathieu (PHMV) beams. The theoretical mechanism regarding the construction PHMV beams was divided into two parts: generation (HM) using stationary phase method and then Fourier transform HM Accordingly, experimental system for generating built follows. Based on complex amplitude modulation method, different orders ellipticity were generated an amplitude–type spatial light modulator (SLM)...
A high sensitive temperature sensor based on photosensitive optical fiber is proposed in order to detect the special environment real time. After cutting end faces of a single-mode and (PF) into flat, put them fusion machine for manual discharging. Because tension effect surface, an face will be fused microsphere at moment discharging, then two microspheres peanut structure through The has same functions as beam splitter combiner interferometer. Considering that refractive index core...
The study proposed a temperature sensor based on distilled water cladding of the coupling region in loop-fiber coupler, which was formed by folding single-mode fiber, melting taper with an H <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> flame, and using two adjacent fibers to obtain interference coupling. Based thermo-optical effect response principle, increasing ambient temperature, refractive index decreased, spectrum drifted....
Abstract As an underlying computer vision task, blind image quality assessment plays important role in evaluation. According to the Human Vision System (HVS), when observing image, people's visual attention will be more sensitive region of their concern, which shows that mechanism is very helpful for assessment. Therefore, assessment, many mechanisms were used extract features concerned regions. However, most existing methods only cascaded multiple features, greatly weakened effect fusion...
Abstract Super-resolution Reconstruction (SR) refers to the process of obtaining high resolution (HR) images from low (LR) images. In recent years, with vigorous development deep learning, SR technology has been more widely applied, especially those based on convolution neural network (CNN). Although some existing methods use multi-scale for feature extraction, most them improve performance by deepening depth, often ignoring intrinsic correlation between different hierarchic features. As is...
