Will manufacturers choose the M6 or M12 format?
The M6 format was recommended by LONGi in June 2019. It would have been selected by this company after numerous tests and analyses. This format is adapted to a good integration in the current production equipment.

There is a trend towards the adoption of larger wafer sizes in 2020.
There is a trend towards the adoption of larger wafer sizes in 2020.
The 156.75 mm (M2) wafer had become the standard size since 2017. However, the improvement in cell efficiency seems to have reached a limit in early 2018, once again making the wafer size a hot topic among manufacturers. In the second half of 2018, the 158.75 mm (G1) format was introduced. It has been increasingly adopted and will be the dominant format in 2020 and 2021.

The size of the inserts has a direct effect on the manufacturer's warranty.
In 2013, the P-type panels had 60 cells and 240 W. Now there are P-type and N-type. The panels have a power of up to 400 W and even 450 W.
After the photovoltaic stock market crash in 2012, the industry has focused on cost reduction and product optimisation. Thus, the panels have gone from 60 cells to 72 cells, and the number of bars from 2 to 5. At that time, buyers were attentive to the financial strength of the manufacturers.

The war of the platelet format
M2 inserts with 156.75 mm sides were the standard until 2018 and accounted for 90% of the market. Manufacturers realised that larger inserts increased the conversion rate and lowered production costs. In 2019, Jinko Solar launched its 158.75mm side format, while others were using the M4 format.

Les études paraissent pour montrer l'intérêt des plus grandes plaquettes (la M6)
Depuis 2018, le débat sur le format des plaquettes est vif. Plusieurs fabricants proposent des tailles de 156,75 mm, 157,0 mm, 157,75 mm, 158,75 mm, 161,7 mm, 166 mm. La diversité des formats a déstabilisé le marché.
En décembre 2013, quelques sociétés PV (dont LONGi) ont annoncé qu'elles adoptaient les plaquettes monosilicium (appelées M1) de 156,75 x 156,75 mm (ayant 205 mm de diamètre) ainsi que des plaquettes dénommées M2 de 156,75 x 156,75 mm de type p (ayant 210 mm de diamètre). Il a fallu six trimestres pour achever la normalisation.
Actuellement, les équipements des producteurs de plaquettes, cellules et panneaux sont conçus pour adopter différentes tailles jusqu'à 166 mm.

Cell format war bounces back with 12-inch (210 mm)
Zhonghuan Semiconductor presents a 12-inch wafer. The manufacturer claims that this wafer improves the efficiency of a panel. If used with a P-type PERC panel, it could have an output power of 610 W with 60 cells, using half-cut solar cells.

The war of wafer sizes is on.
By recommending M6 inserts with 166 mm sides, LONGI started the wafer war. This larger size than the traditional M2 size (156 mm side length) provides a larger light receiving area.

La plaquette va passer de 156 mm à 166 mm
Après avoir vendu 2 GW de panneaux H-MO4 depuis son lancement (ils utilisent des plaquettes M6 de 166 mm), LONGi plaide pour que cette dimension devienne le standard de la profession et que la taille de 156 mm (M2) soit abandonnée. LONGi adaptera toutes ses installations d'ici fin 2020 à cette nouvelle dimension.

Cast inserts come on the market
Moulded monosilicon wafers were at the centre of discussion at the SNEC exhibition. The manufacturing method is more advanced than it was a few years ago. The casting process uses solidification system furnaces to reduce the oxygen content and therefore has a lower LID than monosilicon products. In addition, efficiency and appearance have already improved,
