Slow crack growth in single-crystal silicon

WebbA comparison of the bonded silicon on a silicon wafer with an unbonded, unbonded, single crystalline silicon shows, for example, that both have so-called "grown defects." … WebbSingle crystalline silicon is usually grown as a large cylindrical ingot producing circular or semi-square solar cells. The semi-square cell started out circular but has had the edges cut off so that a number of cells can be more efficiently packed into a rectangular module. Orientation and Doping
