Abstract High work function vanadium oxide (V 2 O X , < 5) is expected to induce strong upward band bending at crystalline silicon ( c ‐Si) surface thus selectively collect photogenerated hole‐carriers. However, the performance of ‐Si solar cells employing V ‐based hole‐selective contacts still under expectation. Herein, we improve hole‐selectivity in combination with NiO . The innovative /NiO stack shows reduced contact resistivity but deteriorated minority carrier lifetime due undesired...
Designing effective carrier-selective contact is a prerequisite for high-efficiency crystalline silicon (c-Si) solar cells. Compared to doped thin films, wide-band-gap transition metal oxides (TMOs) feature low parasitic absorption, but their carrier selectivity and passivation being poor leads mediocre cell efficiency. Herein, we introduce NiOx/MoOx bilayer as an efficient hole-selective in c-Si A power conversion efficiency (PCE) of 21.31% achieved using bilayer, outperforming cells with...
Dopant-free carrier-selective contacts based on metal compounds have attracted considerable attention for high-efficiency crystalline silicon solar cells. In this work, the feasibility of using molybdenum oxynitride (MoOxNy) as an electron-selective contact layer in n-type (n-Si) cells has been demonstrated. With increase N2:Ar ratio during sputtering process, work function a MoOxNy film decreases from 4.57 to 4.26 eV, which is advantageous be electron transport layer. An efficiency 18.0%...
Despite the widespread use of metal oxides as electron selective contacts (ESCs) in dopant-free passivating contact crystalline silicon (c-Si) solar cells, their stability and performance improvements still encounter bottlenecks. Herein, we investigated potential zinc sulfide (ZnS) ESC for n-type c-Si (n-Si) cells. The ZnS-based n-Si cells has been optimized by deploying low work function Mg/Ag stack electrode a SiOx passivation interlayer with forming gas annealing (FGA) treatment. An...
Ni–W alloys have received considerable interest as a promising structural material for microelectromechanical systems (MEMS) due to their exceptional properties, including hardness, ductility, corrosion resistance, and thermal stability. However, the electrodeposition of in MEMS fabrication process achieve intact structures with thickness several tens micrometers is challenging occurrence cracking caused by side reactions internal stresses during process. To address this issue, our focus was...
Graphite industry wastewater is extremely acidic with high levels of toxic ions, and there no efficient economical way to treat it. In this paper, the graphite was treated by a synergistic process NaOH neutralization, Ca(OH)2 mid-stage coagulation, compound agent flocculation. This treatment used reduce amount sedimentation quality during flocculation improve fluoride removal efficiency. The results showed that when pH = 2 adjusted continued 8 Ca(OH)2, precipitation produced 62% lower than...
