ABSTRACT OF THE DISCLOSURE A method is provided for producing solar cells employ- ing slightly curved or nearly flat monocrystalline silicon ribbons. The ribbons are formed by cutting or slicing monocrystalline hollow tubes along their lengths. The tubes may be provided initially by growing the latter from the melt according to the EFG Process. As is well known in the art, in the EFG Process, monocrystalline hollow tubes may be grown from a thin film of melt which is supported on the upper end surface of a suitably shaped die member that has one or more capillaries for feeding melt to its upper end surface from a reservoir pool so as to automatically replenish the film.
