Because of its thermal stability, lead-free composition, and nearly ideal optical electronic properties, the orthorhombic CsSnI3 perovskite is considered promising as a light absorber for all-inorganic solar cells. However, susceptibility this three-dimensional toward oxidation in air has limited development cells based on material. Here, we report findings computational study which identifies Rb y Cs1-y Sn(Br x I1-x )3 perovskites cell applications, prepared by substituting cations (Rb Cs)...
We have used 3-D optical modelling to investigate light management concepts based on periodic textures and material optimization for photovoltaic devices Cu(In,Ga)Se2 (CIGS) absorber material. At first, calibration of the software characterization a reference (1500-nm thick) CIGS device was carried out. The effects 1-D 2-D symmetric gratings cell were then investigated, showing significant improvement in anti-reflection effect absorptance active layer, achieved by excitation guided modes...
Hydrogen interaction with ruthenium is of particular importance for the ruthenium-capped multilayer reflectors used in extreme ultraviolet (EUV) lithography. causes blistering, which leads to a loss reflectivity. This problem aggravated by tin. study aims uncover mechanism via tin affects hydrogen uptake, view mitigation. We report here results surface presence using Density Functional Theory and charge density analyses. Our calculations show significant drop energy barrier penetration when...
Hydrogen permeation into mirrors used in extreme ultraviolet lithography results the formation of blisters, which are detrimental to reflectivity. An understanding mechanism via hydrogen ends up at interface between top ruthenium layer and underlying bilayers is necessary mitigate blistering damage. In this study, we use density functional theory examine ways hydrogen, having entered near-surface interstitial voids, can migrate further metal or its surface. We show that with tin adsorbed on...
Ruthenium (Ru) thin films are used as protective caps for the multilayer mirrors in extreme ultraviolet lithography machines. When these exposed to atomic hydrogen (H), it can permeate through Ru, leading formation of hydrogen-filled blisters on mirrors. H has been shown exhibit low solubility bulk but nature diffusion Ru and its contribution mechanisms blistering remain unknown. This work makes use reactive molecular dynamics simulations study influence imperfections a film behavior H. For...
An atomistic description of tin deposition on ruthenium and its effect blistering damage is great interest in extreme ultraviolet (EUV) lithography. In EUV machines, debris from the EUV-emitting plasma may be deposited mirrors optical path. Tin facilitates formation hydrogen-filled blisters under top layer multi-layer mirrors. We have used Density Functional Theory (DFT) to show that a clean surface exhibits film-plus-islands (Stranski-Krastanov) growth mode, with first atomic bonding...
Currently PV modules are positioned to receive the highest amount of incident radiation in a year. Therefore, generation pattern is independent consumption and large storage required compensate for same. This paper studies possibility orienting differently order match more efficiently.
Performance of thin CIGS solar cells on periodic gratings was investigated. Optical simulations delivered the optimal grating dimensions and demonstrated benefits having a MoO3 buffer layer to quench optical losses in molybdenum.
2.25Cr1Mo0.25V is a state-of the-art alloy used in the fabrication of modern hydrogenation reactors.
Ruthenium thin films can serve as protective caps for multi-layer extreme ultraviolet mirrors exposed to atomic hydrogen. Hydrogen permeation through ruthenium is problematic it leads blisters on the mirrors. H has been shown exhibit low solubility in bulk Ru, and rapidly diffuses out of Ru. Therefore, underlying mechanisms blistering effect remains unknown. This work makes use reactive molecular dynamics simulations study influence imperfections a Ru film behaviour H. For Ru/H system,...
