Abstract

Abstract: Using multicrystalline silicon miscellaneous materials for ingot casting, optimizing the ingot casting process and charging formula, the utilization rate of silicon material is 66.15%, effectively improving the utilization of multicrystalline silicon miscellaneous materials. The minority carrier lifetime of the silicon block is 5.02us, which meets the requirements of solar cell products. The other electrical properties of the silicon block meet the needs of the product, and the miscellaneous ingots realize the reuse of resources, greatly reducing production costs and improving benefits.
