Photovoltaic panel silicon wafer specifications and dimensions

How big is a silicon solar wafer?

Even if silicon solar wafers have been growing ever since, for quite a long period of time wafers have remained at a length of 156.75 mm, the so called generation M2. In the last 2 years the photovoltaics industry is undergoing a rapid change from the M2 standard to larger wafer sizes.

How big is a PV wafer?

Counting the iterative trajectory of PV wafer size, from 125mm to 166mm, from 182mm to 210mm, even though the size is getting bigger and bigger, but the shape has always been square, which has almost become a thinking stereotype in the PV industry.

What size is a monocrystalline silicon wafer?

Before 2010, monocrystalline silicon wafers were dominated by 125mm x 125mm width (165mm silicon ingot diameter) and only a small number at 156mm x 156mm (200mm silicon ingot diameter). After 2010, 156mm x 156mm wafers increasingly became the popular choice (lower cost per-watt) for p-Type monocrystalline and multicrystalline wafer sizes.

What is a solar wafer?

The “wafer” is the starting material for the production of crystalline solar cells, which is only about 200 µm thick. Although there have been many adjustments over the years, the continuity has unfortunately disappeared. In recent months, countless new wafer sizes have appeared on the market. Something the PV industry has never experienced before.

Which type of monocrystalline silicon solar wafers will be launched in 2020?

Time to 2019, M6 (166mm x 166mm) p-Type mono wafers (223mm diameter silicon ingot) was lauched. The 6” format M2 (156.75mm x 156.75mm) was expected to be placed by G1 and M6. In the same period of 2019, M12 (G12) M10 M9 were launched and would be industralized in year 2020. 1 Type Of Monocrystalline Silicon Solar wafer Note: L= length; D=Diameter

What is a standard wafer size?

This was followed by the dimension of 156 mm, which has been defined as a standard for more than 10 years. For this module size, the term “M0” wafer size has established itself over the years. Eventually it was successively replaced by the introduction of the M2 variant with 156.75 mm.
