Photovoltaic panel hot knife

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.

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 a quick hot knife separate glass from solar cells?

Latunussa et al. (2016) developed a quick hot knife method, funded by the EU Life program, to efficiently separate glass from solar cells within 50 s while preserving the integrity of the glass.

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.

What is the functional unit of a hot knife analysis?

The functional unit of this analysis is the delamination of 1 kg of used framed c-Si PV modules at the place of installation. A questionnaire was sent to the manufacturer of the hot knife technology. The manufacturer was asked to provide information on their energy and material consumption and the amount and quality of the recovered materials.
