6 FAQs about [Hot knife method for photovoltaic panels]

Does hot knife technology separate c-Si photovoltaic module front glass from backsheet?

The objective of this study is to complete a life cycle assessment (LCA) of a novel technology that separates the crystalline silicon (c-Si) photovoltaic (PV) module front glass from the backsheet using hot knife technology.

Can a hot knife be used to recycle PV modules?

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.

What is the hot knife delamination process of c-Si PV modules?

The hot knife delamination process of c-Si PV modules is automated in a PV module disassembly line that consists of a junction box (J-box) separator, a frame separator, and a glass separator (hot knife technology), and it involves the following three steps: – Removal of the J-box, after which cables are removed from the separated J-box

What is the hot knife method?

As we strive to build a cleaner, greener future, embracing PV recycling emerges as a fundamental pillar in the transition towards a sustainable energy landscape. As proven by the Task 12 report, the Hot Knife method represents an innovative approach to address the challenges of PV module recycling in an environmentally efficient way.

Does hot knife treatment affect a slanted C-Si PV system?

We find that the hot knife treatment of decommissioned c-Si PV modules causes a very small share of the life cycle environmental impacts of a 3-kWp PV system mounted on a slanted roof in Europe, according to the analysed environmental indicators.

Can PV modules be recycled?

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.
