To address these challenges, First Solar implemented a system capable of virtual individual wafer tracking, and harnessed that system (along with sound statistical principles, ‘big data’ approaches and a touch of engineering creativity) in its TetraSun silicon solar cell production line.
Schematic process flow for an industrial crystalline silicon solar cell line. 1. The entrance interface is the wafer in a stack. As a first step the wafers are typically inspected for microcracks using infrared transmission.
To validate the industrial compatibility of TSRR structure, we further prepared textured TSRR wafers and performed some key manufacturing processes for mass production of silicon solar cells based on 182 × 182 mm 2 pseudo-square wafers with an original thickness of 150 μm which are generally used in industry.
