6 Frequently Asked Questions about “Specifications and dimensions of photovoltaic silicon wafers”
What is the prevailing growth in silicon wafer size?
3.2 Analysis of silicon wafer size According to ITRPV 2019, both multi-crystalline silicon wafers and mono-crystalline silicon wafers are predicted to feature prevailing growth in wafer size. It is predicted that the 90% world market share (2018) of M2 (156.75*156.75 mm2)
What are the different types of silicon wafers?
These wafers are known as type M0. With wafer manufacturers pushing the size of the silicon ingots, 2 different types of wafers were produced, M1 and M2. With only a marginal increase in side length being 156.75 mm, their differences lie in the ingots they were cut from.
What are the different types of silicon wafer sizes in 2022?
According to CPIA statistics, in 2022, there are various types of silicon wafer sizes on the market, including 156.75mm, 157mm, 158.75mm, 166mm, 182mm, 210mm, etc., and each occupies a certain market share. In 2022, the combined market share of large-size silicon wafers represented by 182mm (M10) and 210mm (G12) has exceeded 80%.
What is the diameter of a silicon wafer?
The diameter of the silicon wafers are specifi ed either in inches or mm. Although an inch is 25.4 mm, the diameters of wafers in inches are usually multiples of 25.0 mm (e.g. 4 inches = 100 mm), which should be clarifi ed beforehand with the supplier.
What do m and G stand for in solar wafer size?
What do "M" and "G" stand for in solar wafer size? It begins with the letter "G", which means that the solar silicon wafer is full square Beginning with the letter "M", it means that the solar silicon wafer is Pseudo-square and has chamfer.
What is a 156 mm wafer?
Traditionally, mono-crystalline wafer sizes of 156 mm side length cut from a 200 mm diameter ingots have been used for over a decade. These wafers are known as type M0. With wafer manufacturers pushing the size of the silicon ingots, 2 different types of wafers were produced, M1 and M2.
