Kerf-less Wafers – Start-Ups Working On True Revolution For Crystalline Silicon Solar Wafer Manufacturing

Reducing silicon consumption has always been the focus of PV manufacturers – and it still makes a lot of sense. Though silicon is not expensive these days, this core material for most cells is still a significant contributor to module costs - with a share of over 20% for the cost leaders. One way to reduce silicon usage per cell is to decrease the thickness of the wafer. An even more interesting option is to reduce the so-called kerf. As much as close to 50% of the silicon is lost as waste (kerf) during the ingot sawing process to produce wafers. While reducing kerf losses is on the agenda of wafer makers, some companies, especially start-ups, are trying to eliminate kerf losses completely. Their kerf-less solutions not only dramatically save on silicon raw material, if it worked in large-scale manufacturing, it could revolutionize today’s value chain for crystalline silicon modules by eradicating the upstream production processes of ingot growing and wafering, but depending on the process, even polysilicon production. According to one company active in that field, NexWafe, their technology could save up to 60% of silicon lost during sawing, reduce energy consumption during manufacturing by up to 80%, and require 70% less investment cost for its scrap-free wafer production.

We are looking forward to discussing innovate PV technologies, such as kerf-less wafering, at the upcoming 33rd EU PVSEC in Amsterdam, The Netherlands, from 25-29 September 2017. If you are working in the solar research field, please participate in our Call for Papers and provide us with your abstract by 10 February 2017.
