What is a producer of solar cells from silicon wafers?
Producers of solar cells from silicon wafers, which basically refers to the limited quantity of solar PV module manufacturers with their own wafer-to-cell production equipment to control the quality and price of the solar cells. For the purpose of this article, we will look at 3.) which is the production of quality solar cells from silicon wafers.
How are silicon wafers made?
Silicon wafers come from cutting silicon ingots into thin discs. The ingots start as melted silicon that is cooled and solidified. Special tools, like wire saws, are then used for cutting. This makes the wafers thin and even, which is important for making solar cells later.
