polycrystalline silicon ingot furnace refers to a device that heats and melts the polycrystalline silicon raw material through a graphite resistance heater under vacuum state and protection of inert gas, and then grows the polycrystalline silicon ingot in a strictly controlled temperature field by directional solidification method.
At present, polycrystalline silicon ingot furnaces are mainly used to prepare silicon ingots for solar photovoltaic cells. Although the crystal silicon material prepared by polycrystalline silicon ingot furnace is relatively low in photoelectric conversion efficiency, compared with the direct pull single crystal technology of single crystal growth furnaces, the method of polycrystalline silicon ingot furnaces using directional solidification technology to produce silicon ingots has obvious advantages in terms of production cost, energy consumption, etc.
The advantages and disadvantages of straight-pull single crystal and polycrystalline ingots are better than

my country's polycrystalline silicon ingot furnace market started late, and in the early stage it was mainly imported, and there were fewer applications. In recent years, with the rapid development of my country's solar photovoltaic industry, the demand for polycrystalline silicon ingot furnace equipment has gradually increased. Especially since 2009, the domestic polycrystalline silicon ingot furnace market has shown a rapid growth momentum. According to statistics from the China Electronics Special Equipment Industry Association, in 2009, the sales volume of domestic polycrystalline silicon ingot furnaces was 102 units, with a sales volume of 255 million yuan; in 2010, the sales volume of domestic polycrystalline silicon ingot furnaces reached 302 units, with a sales volume of 755 million yuan, with a growth rate of nearly 200%.

At present, my country's polysilicon ingot furnace is mainly dominated by foreign suppliers, but the market share of domestic manufacturers is expanding rapidly. Before 2007, the domestic polysilicon ingot furnace market was monopolized by foreign manufacturers such as GT Solar. Since 2008, with the continuous improvement of technology and technology, domestic polycrystalline silicon ingot furnaces have gradually achieved large-scale production and have begun to replace foreign products with higher cost-effectiveness. At present, foreign manufacturers still account for a major share in the domestic polycrystalline silicon ingot furnace market. Against the background of the rapid development of the downstream solar photovoltaic industry and the high market share of foreign manufacturers, there is a lot of room for domestic polycrystalline silicon ingot furnace equipment to replace imports. As the production processes and technologies of domestic manufacturers continue to mature, it is expected that domestic polysilicon ingot furnaces will gradually occupy the main share of the domestic market
