It has been suggested that the use of a crucible cover can reduce the carbon impurity of multicrystalline silicon in a unidirectional solidification furnace. The material of the cover has an obvious effect on the impurity concentration. If the cover is made from an inertia material, such as tungsten

The solidification rate of multicrystalline silicon made by directional solidification has been determined by in situ measurements of the solid/liquid interface position in a pilot-scale furnace. Two experiments were conducted where silicon was solidified vertically from the bottom with a nearly pla
The subject of the present paper is to design the technique of laser texturization for solar cells made of multicrystalline silicon and improve understanding of the interaction between laser light and workpiece. We explore how different transverse modes influence laser surface treatment and examine
