WebAug 25, 2024 · We first report PSi Schottky-type heterojunction solar cells by employing graphene transparent conductive electrodes doped with silver nanowires (Ag NWs). The PSi is formed based on metal-assisted chemical etching process, and its porosity is controlled by varying the deposition time (td) of Ag nanoparticles used for the etching. WebAug 25, 2024 · Here, we first successfully fabricate graphene/PSi heterostructure solar cells in a typical Schottky diode configuration, where PSi acts as a photoexcitation layer that exhibits large absorption and high efficiency in the generation of electron-hole pairs in the near-UV range, compared to bulk Si. porter memorial library blandford ma

WebTensile Modulus - or Young's Modulus alt. Modulus of Elasticity - is a measure of stiffness of an elastic material. It is used to describe the elastic properties of objects like wires, rods or columns when they are stretched … WebUsing state-of-the-art first-principles calculations, we propose a new two-dimensional (2D) carbon allotrope constructed by polymerizing the carbon skeletons of s-indacenes, … Graphene is the strongest material ever tested, with an intrinsic tensile strength of 130 GPa (19,000,000 psi) (with representative engineering tensile strength ~50-60 GPa for stretching large-area freestanding graphene) and a Young's modulus (stiffness) close to 1 TPa (150,000,000 psi). See more Graphene is an allotrope of carbon consisting of a single layer of atoms arranged in a hexagonal lattice nanostructure. The name is derived from "graphite" and the suffix -ene, reflecting the fact that the See more Electronic Graphene is a zero-gap semiconductor, because its conduction and valence bands meet at the Dirac points. The Dirac points are six locations in See more A rapidly increasing list of production techniques have been developed to enable graphene's use in commercial applications. Isolated 2D crystals … See more In addition to experimental investigation of graphene and graphene-based devices, their numerical modeling and simulation have been an important research topic. The Kubo formula provides an analytic expression for the graphene's conductivity and shows that it is … See more Structure of graphite and its intercalation compounds In 1859, Benjamin Brodie noted the highly lamellar structure … See more Graphene is a single layer (monolayer) of carbon atoms, tightly bound in a hexagonal honeycomb lattice. It is an allotrope of carbon in the form of a plane of sp2-bonded … See more Monolayer sheets In 2013 a group of Polish scientists presented a production unit that allows the manufacture of continuous monolayer sheets. The process is based on graphene growth on a liquid metal matrix. The product of this … See more porter media chest
