摘要： A method for producing a silicon ingot, provided with symmetrical grain boundaries, including at least steps made of: (i) providing crucible with longitudinal axis, bottom of which includes a paving formed from monocrystalline cuboid silicon seeds with a square or rectangular base and arranged contiguously, the paving, when viewed according to axis, being in shape of a grid of orthogonal directions (x) and (y) parallel to edges of seeds; and (ii) proceeding with controlled solidification of silicon by growth on seeds in a growth direction collinear to axis; wherein paving in step (i) is produced from identical silicon seeds, with two seeds contiguous in direction (x) being images of each other by turning axis (y) and two seeds contiguous in direction (y) being images of each other by turning axis (x), and misorientation 2θ between crystalline arrays of two contiguous seeds being greater than 4°.
