WebGrains are volumes, inside crystalline materials, with a specific orientation. Particles can be polycrystalline, single crystal or amorphous. A 100 nanometer particle of gold, for instance, can... Grain boundaries are interfaces where crystals of different orientations meet. A grain boundary is a single-phase interface, with crystals on each side of the boundary being identical except in orientation. The term "crystallite boundary" is sometimes, though rarely, used. Grain boundary areas contain those atoms that have been perturbed from their original lattice sites, dislocations, and impurities that have migrated to the lower energy grain boundary.

WebPolycrystalline structures 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 … WebIt used to be thought that large grain crystals were the most suitable for multicrystalline silicon solar cells since larger crystals meant fewer grain boundaries. However, in recent years it was found that smaller grains gave lower stress at the ground boundaries so they were less electrically active (lower recombination).
