Scientists in the Netherlands have proposed a new testing scheme for recycling silicon from end-of-life photovoltaic panels.Their methodology helps create different wafer categories for recycling silicon, with a focus on gallium-doped wafers for new ingot production.Most of the recycled silicon in the near future will come from p-type products, which may face challenges in a market dominated by n-type modules.Reusing p-type wafers as feedstock for new p-type ingots may not be economically viable, considering the dominance of n-type cell technology.
