Do photovoltaic panels need lead
In this review, we summarize the latest progress on investigating the lead safety issue on photovoltaics, especially lead halide perovskite solar cells, and the corresponding solutions. We also outlook the future development towards solving the lead safety issues from different aspects.

Lead in PV In spite of this, a typical 60-cell crystalline silicon solar module produced today contains up to 12 grams of lead. This lead is primarily found within the ribbon coating and.
In this review, we put forward a different perspective, focusing on concepts such as cost, availability, sustainability and eco-friendliness required to justify the large-scale use of lead alternatives in the PV industry.
Perovskite photovoltaics has become more competitive against silicon counterpart in reducing cost of solar energy, yet the management of toxic lead hampers it application. Here, the authors.
Lead is present in around 33% of the thin coating on top of copper conductors in PV modules, and concerns about lead leaching from solar panels are widespread.
6 FAQs about [Do photovoltaic panels need lead ]
Should photovoltaic panels use lead?
It is argued that the advantages of using lead in photovoltaic panels, when including proper encapsulation and recycling, outweigh the risks associated with its manufacturing. Finally,...
Are fixed PV panels exempt from the lead regulation?
It is worth noting that fixed PV panels are exempt from this regulation as it only applies to portable PV panels. The evaluated lead concentration is 344 ± 4 mg/kg and 22,400 ± 100 mg/kg for perovskite thin films on glass and flexible polyethylene terephthalate (PET) substrates, respectively, as shown in Fig. 2b.
Can PV products cause lead pollution?
Given the relatively small amounts of lead used by the PV industry, and the fact that the lead is enclosed entirely within the module materials, it is unlikely that PV products by themselves would be the cause of major lead pollution, even in a worst-case scenario with a large percentage of panels ending up in landfill.
Are solar panels leaching lead from solder joints?
There are fears around lead leaching from solder joints in solar panels and the potential presence of per- and polyfluoroalkyl substances (PFAS), also known as ‘forever chemicals’, in module back sheets.
Are photovoltaic panels regulated by EU legislation?
EU legislation limits the content of lead in ‘homogeneous materials’ to 0.1% by weight. With that said, photovoltaic panels, “intended to be used in a system that is designed, assembled and installed by professionals for permanent use at a defined location”, are already exempt from this limitation 69.
Are perovskite photovoltaics dangerous?
Lead in perovskite photovoltaics poses potential risks to human health and ecosystem. Water-soluble and bioavailable lead that leaks from damaged PSCs is dangerous. Fail-safe encapsulation and safe device configuration are developed for lead leakage. End-of-life PSCs as hazardous wastes should be taken into account before commercialization.
