Products Description
The difference between Monocrystalline and Polycrystalline
Solar photovoltaic cells, or PV cells are made using silicon crystalline wafers which are similar to the wafers used to make computer processors. The silicon wafers can be either polycrystalline or monocrystalline and are produced using several different manufacturing method. The most efficient type is (mono) which are manufactured using the well known Czochralski process. This process is more energy intensive compared to polycrystalline (poly) and therefore more expensive to produce.
Solar cell
1.silicon is extracted from sand, but not just any sand. The sand used, known as silica sand or silicon dioxide, is usually made from crushed quartz rock.
2.The silica sand must then be purified using a process called Carbon Arc Welding (CAW) which extracts the unwanted oxygen and results in 99% pure silica. The silica is then further processed to become as close to 100% pure silicon.
3.The end result is very pure polycrystalline silicon which can be doped with trace amounts of either boron or phosphorous to become either P-type or N-type silicon.
4.At this stage the polycrystalline silicon can be melted and cast into a large rectangular blocks and thinly sliced using a diamond wire cutting method to produce the polycrystalline or multicrystalline wafers.
