Advancing circular economy in photovoltaics: The Hot Knife PV module recycling method
Recycling is of significant importance in a circular economy, yet some challenges have to be faced when recycling PV modules. The novel Hot Knife method to separate the crystalline silicon photovoltaic module front glass from the backsheet contributes only a few permill to the life cycle related potential environmental impacts of PV electricity.

Recycling has emerged as a pivotal element in forging a circular economy within the photovoltaic (PV) industry, enabling a sustainable and resource-efficient future. While the durability of PV modules presents a challenge for recycling efforts, a novel solution has surfaced in the form of the Hot Knife method. Collaborating with a leading technology manufacturer, Task 12 of the International Energy Agency’s Photovoltaic Power Systems Programme (IEA PVPS) has released a new report, offering a comprehensive environmental life cycle assessment of this innovative PV recycling technique.
