Crystalline ingot

WebAs soon as the crystal ingot is obtained using the above processes, the extreme top and bottom portions of the ingot are cut off and the ingot surface is grounded to produce a constant and exact diameter. The normal diameter is usually 100,125, or 150 mm. A crystallographic orientation flat is also ground along the length of the ingot. WebJul 13, 2024 · Monocrystalline solar cell ingots are made using the Czochralski method [ 3 ]. The Czochralksi method is a process of obtaining a single crystal of semiconductor. This process was discovered by a Polish scientist named Jan Czochralski. He discovered by luck while he was investigating the crystallization rates of metals.
