A METHOD FOR MANUFACTURING MULTI-CRYSTALLINE SILICON WAFER FOR SOLAR CELL

摘要

The present invention relates to a method for manufacturing a multi-crystalline silicon wafer for a solar cell. More particularly, the present invention relates to a method for manufacturing a multi-crystalline silicon wafer for a solar cell with good quality by a simple and economical method. Doped polysilicon sheet is manufactured by slicing the doped polysilicon rod manufactured by a Simens method. After that, a re-crystallization process is performed.
