    Multicrystalline silicon brick

    Multicrystalline silicon brick

    Multicrystalline silicon brick is made by directional silicon solidification.JY makes full uses of the industry's mainstream crystal growth methods,equipped with advanced manufacturing facilities, and furnished with its advantages in independent ingot technology.All these make JY’s multi brick is of low impurities,low defects, and high&stable efficiency. Brick size in 156.75mm and 157mm are the mainstream products currently.Meanwhile, we can produce various non-conventional size according to custom requirements.
