Antimony selenide (Sb2Se3) has a one-dimensional (1D) crystal structure comprising of covalently bonded (Sb4Se6)n ribbons stacking together through van der Waals force. This special results in anisotropic optical and electrical properties. Currently, the photovoltaic device performance is dominated by grain orientation Sb2Se3 thin film absorbers. Effective approaches to enhance carrier collection overall power-conversion efficiency are urgently required. Here, we report construction solar...
Binary Sb2 Se3 semiconductors are promising as the absorber materials in inorganic chalcogenide compound photovoltaics due to their attractive anisotropic optoelectronic properties. However, solar cells suffer from complex and unconventional intrinsic defects low symmetry of quasi-1D crystal structure resulting a considerable voltage deficit, which limits ultimate power conversion efficiency (PCE). In this work, creation compact films with strong [00l] orientation, high crystallinity,...
Energy band alignment plays an important role in heterojunction thin-film solar cells. In this work, we report the application of ternary CdxZn1–xS buffer layers antimony selenide (Sb2Se3) The results our study revealed that Cd/Zn element ratios not only affected optical gap buffers but also modified at junction interface. A Sb2Se3 cell with optimal conduction-band offset value (0.34 eV) exhibited efficiency 6.71%, which represents a relative 32.1% enhancement as compared to reference...
Abstract Although a widely used option in contemporary anticancer treatment, surgery still causes serious issues, including post‐operation recurrence and the development of metastases. Immunotherapy, often following surgical resection tumor, has demonstrated benefits improving therapeutical outcomes surgery. However, antigen generation presentation play an essential role reversing limited T‐cell responses or immunological resistance. Thus, gelatin‐tannic acid gel (GelTA) crosslinked...
ABSTRACT A novel low‐cost SiO 2 /Polyvinylchloride (PVC) membrane with different nano‐SiO particles loading (0–4 wt %) was prepared by the phase‐inversion process. The optimum dosage determined as 1.5 % based on casting solution compositions, membranes' mechanical properties and hydrophilicities, pure water fluxes, microstructures, absorption of protein. Compared bare membrane, addition presented better capabilities against protein bacterial attachment, antifouling performance, higher flux...

Scanning electron microscopy (SEM) images showed that additional modified growth process surface morphology films. X-ray diffraction (XRD) patterns confirmed enhanced beneficiary preferred orientations, capacitance–voltage ( C – V ) measurement carrier concentration absorber increased with evaporation Se. Accordingly, efficiency devices...
In order to address the present difficulty in experimentally generating relativistic Laguerre-Gaussian laser, primarily due damage caused optical modulators, a high-reflectivity phase mirror is applied femtosecond petawatt laser system generate hollow at highest intensity of 6.3×10^{19} W/cm^{2} for first time. A simple model used verify that vortex may be generated this new scheme; using such plasma drill and acceleration are achieved proven by particle-in-cell simulations. With development...
Leber's hereditary optic neuropathy (LHON) is a maternally inherited eye disease. X-linked nuclear modifiers were proposed to modify the phenotypic manifestation of LHON-associated mitochondrial DNA (mtDNA) mutations. By whole-exome sequencing, we identified LHON modifier (c.157C>T, p.Arg53Trp) in PRICKLE3 encoding protein linked biogenesis ATPase 3 Chinese families. All affected individuals carried both ND4 11778G>A and p.Arg53Trp mutations, while subjects bearing only single mutation...
Abstract Deep‐level defects in semiconductor materials usually induce carrier trapping and non‐radiative recombination.

The analysis of deep‐level transient spectra reveals that an increase...
Antimony selenide (Sb2 Se3 ) nanorod arrays along the [001] orientation are known to transfer photogenerated carriers rapidly due strongly anisotropic one-dimensional crystal structure. With advanced light-trapping structures, Sb2 array-based solar cells have excellent broad spectral response properties, and higher short-circuit current density than conventional planar structured thin film cells. However, interface engineering for cell is more crucial increase performance, because it...
