Abstract:
A method for eliminating metal composites from a polycrystalline silicon cell piece, comprising the steps of: injecting current into the polycrystalline silicon cell piece under a certain temperature by means of an electric injection method, thereby eliminating the metal composites from the interior of the polycrystalline silicon cell piece; the present invention discloses a simple process, a short processing-time, a low manufacturing cost, and can easily be scaled for manufacture.

Claim (Index 7):
The method for eliminating metal composites from a polycrystalline silicon cell piece of  claim 6 , wherein the front surface of the polycrystalline silicon cell piece is textured via a wet black silicon texturing method, wherein the front surface of the polycrystalline silicon cell piece is provided with five main gate lines, and is plated with a silicon nitride protective film, wherein the back surface of the polycrystalline silicon cell piece is passivated, and is plated with an aluminum-oxide and silicon-nitride laminated film, wherein the outermost layer of the back surface of the polycrystalline silicon cell piece is provided with printed aluminum paste.
