Creating a solar panel with CDs and copper wire is a simple demonstration of the photovoltaic effect, where certain materials generate electric current when exposed to light. Here's a theoretical explanation of how it works:

1. Materials Needed:
- CDs: These act as the base or substrate for the solar panel. CDs are usually made of polycarbonate plastic, which is transparent and can act as a protective layer for the photovoltaic material.
- Copper Wire: This serves as the conducting material to collect the electric current generated by the photovoltaic material.
- Photovoltaic Material: In this case, we'll use a common household material like cuprous oxide (Cu2O), which can be created by heating copper in a specific environment.

2. Preparation of Photovoltaic Material:
- Cuprous oxide (Cu2O) can be created by heating copper in a low-oxygen environment, such as under a layer of sodium chloride (table salt), which acts as a reducing agent.
- Once the cuprous oxide is formed, it can be carefully applied onto the surface of the CD. This can be done by grinding the cuprous oxide into a fine powder and spreading it evenly over the CD surface.

3. Assembly:
- After the cuprous oxide is applied to the CDs, copper wire is then attached to the cuprous oxide layer using conductive adhesive or soldering. This creates an electrical connection between the photovoltaic material and the copper wire.

4. Functionality:
- When exposed to sunlight, the cuprous oxide layer on the CDs absorbs photons from the sunlight, exciting electrons within the material.
- These excited electrons then move through the material, creating a flow of electric current.
- The copper wire connected to the cuprous oxide layer acts as a conductor, allowing the electric current to flow through it.
- By connecting multiple CDs with copper wire in series or parallel configurations, you can increase the voltage or current output of the solar panel, respectively.

5. Output:
- The electric current generated by the CDs can be used to power small devices or charge batteries, demonstrating the conversion of solar energy into electrical energy.
