Unified Silicon Wafer Dimensions Spearheaded by Six Photovoltaic Giants in China

In a significant move to streamline the photovoltaic industry, six leading companies have come together to drive the standardization of silicon wafer dimensions, specifically focusing on the new-generation rectangular silicon wafers with a medium size module format (2382x1134mm). This collaborative effort aims to address challenges arising from variations in silicon wafer sizes, such as supply chain complexities and increased material costs, following the unification of the medium-sized module format dimensions.

Representatives from these six photovoltaic enterprises engaged in comprehensive deliberations and evaluations, resulting in a consensus regarding the standardized dimensions for the 191.Xmm rectangular silicon wafers used in the 72-cell module format. The agreed-upon dimensions are as follows:

• Rectangular silicon wafer margins: 182.2mm x 191.6mm
• Rectangular silicon wafer diameter: 262.5mm

The combined efforts of these six prominent photovoltaic companies aim to advocate for and implement the standardized dimensions of rectangular silicon wafers across the industry. This initiative is poised to gain traction and acceptance among more companies within the photovoltaic sector.

List of Collaborating Companies in the Joint Initiative:

• Canadian Solar
• Risen Energy
• Longi Green Energy Technology
• Tongwei
• Yidao New Energy
• Chint Solar

This collaborative move toward standardized silicon wafer dimensions underscores the industry’s commitment to enhancing efficiency, reducing costs, and streamlining the supply chain. As these major players spearhead this initiative, it is expected that other companies will follow suit, ultimately driving greater cohesion and competitiveness within the photovoltaic sector.
