Abstract:
PURPOSE: An apparatus for manufacturing a silicon substrate using a spin casting process and a method for manufacturing the silicon substrate using the same are provided to easily control the thickness and the shaft of the silicon substrate without a separate shaping unit. CONSTITUTION: A chamber(110) arranges a sealed space. A storing container(122) is arranged in the chamber, and a raw silicon material is introduced in the storing container. A discharging hole is formed at the bottom side of the storing container. A melting part(120) is arranged around the storing container and includes a heater melting the raw silicon material. A casting part(140) spin-casts the melted silicon from the discharging hole. A cooling part(160) cools the spin-cased silicon. A temperature measuring part(180) measures the temperature of the melting part.
Abstract:
PURPOSE: A silicon substrate for the solar battery and the manufacturing method thereof which is manufactured by directly using the manufacturing device, and this the silicon substrate for the solar battery using the continuous casting method keeps the high - liquid interface formed into the substrate growth direction and vertical direction. CONSTITUTION: The melt region(310) forms the molten silicon. The heating portion(312) heats the melt region. A space of casting part(320) casts the fused silicon to the silicon substrate of the plate type. The transport unit(330) horizontally transfers the solidified silicon substrate.
