A solar wafer is a thin slice of a cubic silicon ingot. It is further processed and fabricated into a solar cell, which forms the basic unit of a solar power system. The surface of a multicrystalline solar cell shows multiple crystal grains of random shapes and sizes in random positions and orientations.
Solar equipment makers are in a fierce competition to cut wafer prices, providing some relief for China’s efforts to install a massive amount of renewable power and reach ambitious climate targets. Falling solar material prices have driven down costs along the supply chain in recent weeks, with silicon wafers seeing the largest discount.
The ingot and wafering production steps are power hungry and produce waste in the form of kerf slurry – the residue ingot material from between the sliced wafers. Those are the PV production steps most highly concentrated in China.
Tellingly, Norsun is now trying to establish a 5 GW ingot and wafer production facility in the United States. In August 2023, it announced it had raised NOK90 million ($8.5 million) in capital in pursuit of the plan, alongside the €53.6 million ($58 million) it was awarded by the European Union Innovation Fund. Potential in United States
The NexWafe approach is described as epitaxial and involves gases being deposited onto a seed substrate from which it can be separated and fashioned into a cell. Both approaches can be described as “kerfless” wafer production as they do away with wafer cutting and the waste kerf it produces.
On Jan. 27, 2024, the European Solar Manufacturing Council (ESMC) issued a “plea for survival” to European policymakers. It argued that foreign PV module manufacturers were dumping modules, or selling below cost.
