Companies involved in manufacturing less common types of solar ingot materials.42 manufacturers of these types of solar ingot materials are listed below.
The process of melting polysilicon into ingots and subsequently cutting them into wafers is wedged between polysilicon production and cell manufacturing. It is a distinct process that does not require physical proximity to upstream or downstream processing. Consequently, some companies specialise in just doing that.
Gleaming crystalline silicon ingots emerge from towering pullers to be sliced by diamond wire saws into iridescent, black square, or rectangular, monocrystalline wafers. The ingot and wafering production steps are power hungry and produce waste in the form of kerf slurry – the residue ingot material from between the sliced wafers.

As the process and output of ingot growing and wafer cutting are fairly standardised, it is realtively easy for polysilicon producers to forward-integrate into wafer cutting, thus becoming direct competitors to established wafer cutters.
The fabrication of polysilicon begins with a carbothermic reduction of SiO 2. Quartzite, the source of SiO 2, is mixed with carbon—sourced from materials such as coal, coke (fuel), graphite or wood—in a submerged-arc electric furnace.
