Polycrystalline Materials – Definition - Material Properties
网页What is Polycrystalline Structure – Polycrystalline Materials – Definition. Not all solids are single crystals. When a metal starts with crystallization, the phase change begins with small crystals that grow until they fuse, forming a polycrystalline structure.
Polycrystalline silicon - Wikipedia
网页Polycrystalline silicon, or multicrystalline silicon, also called polysilicon, poly-Si, or mc-Si, is a high purity, polycrystalline form of silicon, used as a raw material by the solar photovoltaic and electronics industry.

Polycrystalline Material - an overview | ScienceDirect Topics
网页Polycrystalline materials are solids that consist of many small crystals (the “grains”). The grains are separated by grain boundaries and normally have random crystallographic orientations. The size of the grains may vary from nanometers to millimeters.
Polycrystal | Grain Boundaries, Microstructure & Crystallinity
网页Polycrystal, any solid object composed of randomly oriented crystalline regions, called crystallites, especially as distinguished from a single crystal (q.v.). Polycrystalline materials result when a substance solidifies rapidly; crystallization commences at many sites (see nucleation), and the.
Monocrystalline vs. Polycrystalline Solar Panels - EnergySage
网页2023年1月9日 · The main difference between the two technologies is the type of silicon solar cell they use: monocrystalline solar panels have solar cells made from a single silicon crystal. In contrast, polycrystalline solar panels have solar cells made from many silicon fragments melted together.
Polycrystalline silicon: applications, and properties - Solar energy
网页2018年10月26日 · Polycrystalline silicon is a material made of misaligned (polycrystalline) silicon crystal. It occupies an intermediate position between amorphous silicon, in which there is no long-range order, and monocrystalline silicon. Polycrystalline silicon has an impurity level of 1 part per billion or less.
Polycrystalline Material - an overview | ScienceDirect Topics
网页Polycrystalline materials, including nano-crystalline materials are made of an ensemble of single crystallites that are assembled through various ways, such as nucleation and growth, mechanical deformation, or inert-gas condensation [1–3]. The unique feature of polycrystalline materials is the so-called microstructure that consists of a set ...
Polycrystalline - an overview | ScienceDirect Topics
网页The term “polycrystalline” refers to a form of a secondary particle with a diameter of ∼20 μm formed by the aggregation of hundreds of nano-sized primary particles, whereas “single-crystalline” refers to a single particle with a diameter of 2–5 μm.
