Summary edit

Description
English: A picture of grain boundaries for polysilicon. Each grain is crystalline over the width of the grain. The grain boundary separates the grains where the adjoining grain is at a different orientation than its neighbor. The grain boundary separates regions of different crystal structure thus serving as a center for recombination. 'd' here is a characteristic grain size, which should be maximized for maximum solar cell efficiency. Typical values of d are about 1 micron.

This diagram image could be re-created using vector graphics as an SVG file. This has several advantages; see Commons:Media for cleanup for more information. If an SVG form of this image is available, please upload it and afterwards replace this template with {{vector version available|new image name}}.


It is recommended to name the SVG file “Grain boundary diagram.svg”—then the template Vector version available (or Vva) does not need the new image name parameter.
