ABSTRACT:
Large surfaced, pore-free silicon bodies useful for processing into solar cells are produced by providing at least two layers formed from at least two distinct silicon materials, each containing different amounts of germanium therein and thus having different melting points. A laminate is formed of such layers and sintered at a temperature at which only one of the silicon materials becomes molten so that the resultant molten layer effectively seals the pores of the other layers and upon cooling a unitary silicon body is attained. In certan embodiments, a molten silicon material is applied as a liquified film onto a solidified layer composed of different silicon material.
