What materials do solar panels contain?

Solar panels contain several different materials, which together form a functioning photovoltaic system. The most commonly used materials in solar panels are:

• Silicon chip: The most important part of solar panels is the silicon chip, which converts sunlight into electricity. A silicon chip can be either polycrystalline or made with thin film technology.
• Glass panel: The glass panel on top of the solar panel protects the solar panel and collects sunlight efficiently.
• Metallic electrodes: Metallic electrodes carry electricity out of the solar panel.
• Backsheet: The backsheet behind the solar panel protects the solar panel from moisture and other external factors.

These materials together form a solar panel that can convert sunlight into electricity. It is important that solar panels are made of high-quality and durable materials so that they last a long time and produce as much electricity as possible.
