How are solar cells made?

The production of solar cells typically follows these key steps:

1. Sourcing materials: The primary material for solar cells is silicon, which is abundant and effective for converting sunlight. Materials like cadmium telluride and copper indium gallium selenide are also used.
2. Purifying silicon: The silicon used in solar cells must be extremely pure. This involves a refining process that removes impurities.
3. Casting the silicon: After purification, the silicon is melted and cast into ingots, which are then sliced into thin wafers.
4. Doping the wafers: To make the silicon cells conductive, a process called doping is applied, adding small amounts of other materials to alter its electrical properties.
5. Applying coatings: A thin layer of anti-reflective coating is added to enhance light absorption.
6. Connecting cells: Multiple solar cells are then connected to create a solar panel, ensuring that they can work together to produce electricity.
