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 are the different types of silicon wafer growth methods?

This Specification allows growth methods that include Czochralski (Cz) method, Floating Zone (FZ) method for single crystal silicon wafers, and casting method with and without seed for cast silicon wafer. The specified cast silicon wafer includes cast silicon category I wafer and cast silicon category II wafer.

Should silicon wafers be square?

The wide range of innovative rectangular sizes has taken the industry by surprise. When Trina Solar launched its new silicon wafer product “210R” in April 2022, the rectangular silicon wafer was made public for the first time, and the decades-old thinking in the PV industry that silicon wafers should be square was completely dismantled.

Why are wafer dimensions standardized?

To permit common processing equipment to be used in multiple fabrication lines, it is essential for the wafer dimensions to be standardized. This Specification provides standardized dimensional and certain other common characteristics of silicon wafers based on currently widely used sizes for photovoltaic applications.

What is a cast silicon wafer?

The specified cast silicon wafer includes cast silicon category I wafer and cast silicon category II wafer. A complete purchase specification requires that various physical properties be specified along with test methods suitable for determining their magnitude.
