An asymmetrical shaped capillary die made exclusively of graphite is used to grow silicon ribbon which is capable of being made into solar cells that are more efficient than cells produced from ribbon made using a symmetrically shaped die.

Displaced capillary dies

A solar cell having a periodic front surface electrode is provided with a transparent cover chosen and configured to provide refractive discontinuities of the same spatial frequency as and aligned with the conductive grid. The refractive discontinuities are so controlled, through selection of the shape, disposition, and refractive index of the cover, as to cause a ray initially normal to the surface of the cell which would otherwise be intercepted by the electrode to miss the electrode and fall on the photosensitive material.
