Abstract
A method and apparatus for manufacturing tape-shaped silicon bodies for solar cells wherein a tape-shaped reticulate carrier is passed vertically downwardly through a drawing nozzle including a slot which is full of molten silicon. The drawing nozzle is located above the level of molten silicon in a vat containing such molten silicon, and capillary means are provided to deliver the molten silicon from the vat into the drawing nozzle to fill the same with the molten silicon.
