🧠 What are Solar Cells Made Of?

 Solar cells, the building blocks of solar panels, are primarily made of silicon, a semiconductor material. Silicon is the most commonly used material in solar cells due to its efficient ability to convert sunlight into electricity.

Key Components of Solar Cells:

1. Silicon:

   • Most solar cells are made from crystalline silicon, which comes in two forms: monocrystalline and polycrystalline.

2. Phosphorus and Boron:

   • These materials are added to silicon to create n-type and p-type layers that enable the photovoltaic effect.

3. Metal Contacts:

   • Metal contacts allow electricity to flow from the cell into the external circuit.

4. Anti-Reflective Coating:

   • A layer is added to reduce light reflection and ensure maximum sunlight absorption.
