A method for manufacturing poly-crystal silicon for solar battery is provided to manufacture the cheap solar battery by using the disposed silicon slurry as the main raw material and to achieve mass production. The disposed water including silicon slurry which is produced in the polishing process of silicon wafer and ingot is passed through the filter including the polyolefin class polymeric composition. The solidified filter layer is formed and then the silicon slurry is filtered. The silicon sludge separated through the filtration process is dried. The dried silicon sludge is melted in the temperature of 1500~1800°C under the inactive state or the vacuum condition. The melted silicon sludge is solidified and purified. |
