6 FAQs about [Wafer and photovoltaic bracket installation process]

Can wire sawing produce crystalline wafers for solar cells?

Wire sawing will remain the dominant method of producing crystalline wafers for solar cells, at least for the near future. Recent research efforts have kept their focus on reducing the wafer thickness and kerf, with both approaches aiming to produce the same amount of solar cells with less silicon material usage.

Why do solar cells need wafer etching?

Finally, the wafering process step, in combination with the material quality, defines the mechanical properties of the final solar cell, as the wafering process can damage the wafer’s surface. This damage has to be etched not only to increase the mechanical stability but also to obtain good cell efficiencies.

How are photovoltaic absorbers made?

The manufacturing typically starts with float glass coated with a transparent conductive layer, onto which the photovoltaic absorber material is deposited in a process called close-spaced sublimation. Laser scribing is used to pattern cell strips and to form an interconnect pathway between adjacent cells.

How are thin film PV modules made?

Thin film PV modules are typically processed as a single unit from beginning to end, where all steps occur in one facility. The manufacturing typically starts with float glass coated with a transparent conductive layer, onto which the photovoltaic absorber material is deposited in a process called close-spaced sublimation.

How to optimize the wire saw wafering process?

The wire saw wafering process is determined by a variety of factors. In order to optimize the wafering process, a large number of tests are necessary; Those presented in this paper illustrate that multi-crystalline wafers can be cut with a thickness down to 70μm while maintaining high quality.

How much kerf can be reduced in photovoltaics?

Wire thickness is the most obvious option for kerf reduction. A wire thickness of 160μm was standard in the photovoltaics industry until 2007. In order to reduce the cost for silicon photovoltaics, this thickness has since been decreased to 100μm. This represents a kerf reduction of about 37%, which is equivalent to about 13kg of silicon Figure 8.
