The present invention relates to an organized assembly of adjacent silicon single crystals for the directional solidification of an ingot along a solidification direction, the oriented single crystals of which, observed over a section perpendicular to the solidification direction Z are such that the disorientation of an oriented single crystal with an adjacent single crystal is greater than 8°, the smallest angle between a normal to the joint separating the single crystal from an adjacent oriented single crystal and the directions <111> of said adjacent single crystal is greater than 4°, the smallest angle between the direction Z and the directions <100> of said single crystal is less than 25° and /or the smallest of the angles between the direction Z and the directions <111> of the single crystal is less than 10°, and the projection distance in a plane perpendicular to the direction Z, of the largest dimension of said single crystal, measured among the planes {111} and along the directions <110>, is less than 40 mm. |
