At LDK Solar, we produce large monocrystalline and multicrystalline ingots. This innovation enables us to increase our yield of ingots and increase the utilization rates of our facilities thus reducing costs by achieving economies of scale. Larger ingots will increase throughput production efficiencies by reducing manufacturing bottlenecks. For example, LDK Solar produced the world's first and largest multicrystalline ingot weighing 800kg. Our ingot manufacturing facilities are located in Xinyu City in Jiangxi province, China.

An ingot is a semiconductor material (e.g. Silicon) that is melted and cast into a shape suitable for further processing. We use our high-purity polysilicon as well as purchased and recycled polysilicon to manufacture our ingots. We test and categorize recycled silicon raw materials based on their technical properties. These recycled silicon raw materials then undergo mechanical grinding and chemical cleaning before they are mixed using our proprietary formula. Our ability to mix the materials in the right proportion is critical to the production of high-quality silicon ingots.
