How are solar panels made?

Silicon is one of the most important materials used in solar panels, making up the semiconductors that create electricity from solar energy. However, the materials used to manufacture the cells for solar panels are only one part of the solar panel itself. The manufacturing process combines six components to create a functioning solar panel.

Should solar panels be mined?

The US solar industry aims to supply 30% of US energy generation by 2030. But manufacturing the solar panels necessary for such a huge increase in solar power production will require a surge in the mining of raw materials. There are myriad problems that exist with the mining of silicon, silver, aluminum, and copper needed to make solar panels.

What are the raw materials and parts of a solar panel?

The table below outlines the raw materials and parts comprising a solar panel. Silicon is the basic material for conductive electrical components. Before it can be used, it must undergo a treatment process that removes impurities and converts it to pure silicon, or polysilicon.

How do solar panels produce electricity?

When sunlight hits the solar cells, it excites the electrons within the material, causing them to move. This movement generates electricity that can be used to power homes, buildings, and even entire power grids. 2. The Raw Materials: The Foundation of Solar Panel Production

Why are solar panels made of silicon?

This is the main reason why most solar panel production focuses on silicon panels. 90% of solar PV panels in production on the market are silicon. Busbars are thin, conductive strips, typically made of copper or aluminum, that collect and distribute electric current generated by individual solar cells within a module.

What is a solar cell made of?

A solar cell is made from a thin wafer of silicon. Each cell is connected to the other cells in the module by thin wires known as busbars. Solar cells are the most expensive part of a solar panel. The quality of solar cells varies depending on the material it is made from. Silicon cells are generally more expensive than thin-film cells.
