6 FAQs about [Metal element content standard of photovoltaic panels]

What metals are used in PV modules?

Among the RCRA 8 metals, lead is typically found in the solder bonds of copper ribbon interconnects, which connect cells and cell strings within silicon-based PV modules. To reduce the use of lead, some new PV modules are adopting lead-free ribbon technology for cell and string interconnections.

What are solar panels made of?

Solar panels are composed of all the components necessary to convert light into usable electricity. This includes the structure, cell material, and protective coating. The most common type of solar cell material is crystalline silicon, which is used in both polycrystalline and monocrystalline solar cells.

What is a photovoltaic (PV) cell?

The photovoltaic (PV) cell is the heart of the solar panel and consists of two layers made up of semiconductor materials such as monocrystalline silicon or polycrystalline silicon. A thin anti reflective layer is applied to the top of these layers to prevent light reflection and further increase efficiency.
