【Abstract】 In this paper, the advantage of polycrystalline silicon ingot using by the technique of derectional solidification growing for solar cell was described. Because of this process having the advantage of less raw material consumption, high utilization rate of ingot, big cross section of ingot, short production period, high volume of production, low investiment, low energy consumption, it would be promising to reduce cost apparently. Comparing to the technique of regrowing single crystal, it is concluded that the cost could reduce by 4% to 20%.更多还原
