Making a solar cell from a CD is not as hard as it may seem. It can be a fun and rewarding project for anyone interested in learning more about solar energy.
This guide will walk you through the entire process, from start to finish, with frequently asked questions (FAQs) included along the way. Let’s get started.

How to Make a Solar Cell From CD
Fortunately, making a solar cell from a CD isn’t too complicated and can be broken down into 4 simple steps.
1. Gather materials
Here’s everything you need to make a solar cell from a CD:
- 1 CD
- 1 Knife or razor blade
- 1 Black sharpie
- 1 Roll of tape
- 2 Alligator clip wires
2. Preparing the CD
Start by taking your CD and using the knife or razor blade to carefully scratch the surface of the CD. Be sure to make scratches that are evenly spaced apart and go in a straight line.
Once you’ve finished scratching the CD, use the black sharpie to color in the scratches. This will help absorb more light and make the solar cell more efficient.
3. Making the Connections
Use the alligator clip wires to connect the positive (red) wire to the scratched and blackened side of the CD, and the negative (black) wire to the non-scratched side of the CD.
Then, use the tape to secure the alligator clip wires in place.
4. Testing the Solar Cell
To test if your solar cell is working, hold it up to a light source (like a lamp or the sun) and see if the wire connected to the blackened side of the CD starts to glow. If it does, congrats! You’ve just made a working solar cell.
How Can I Make a Solar Cell at Home?
Most solar cells you see are made of silicon, but you can also make a solar cell at home using copper oxide and other materials. Here’s what you’ll need:
- Copper oxide (CuO)
- One sheet of conductive glass
- One sheet of fluorine-doped tin oxide (FTO)
- Power source (like a battery or solar panel)
- Silver paint
To start, mix the copper oxide and silver paint together. Then, apply this mixture to the FTO glass. Next, take the conductive glass and apply a thin layer of indium tin oxide (ITO) to it.
Once that’s done, you’ll need to put the two pieces of glass together so that the silver paint is sandwiched between them. Finally, use the voltmeter to measure the voltage between the two pieces of glass.
If everything has been done correctly, you should see a voltage reading on the voltmeter.
How Does Solar Energy Generate From a CD?
CDs are often used to store music or other data, but did you know that they can also be used to generate solar energy? This process begins with the solar cells on the CD.
Solar cells are made of a material that absorbs sunlight and converts it into electrical energy. When the solar cells on the CD absorb sunlight, they generate an electrical current.
This current is then passed through a thin wire that runs along the edge of the CD. The wire is connected to a photovoltaic cell, which converts the electrical energy into solar power. This solar power can then be used to run small devices or to recharge batteries.
Why is Solar Power the Best Energy Source?
Solar power is the best energy source because it’s renewable, meaning we won’t run out of it, and it doesn’t pollute the air like other energy sources.
Solar power is captured with photovoltaic cells and turned into electricity. The electricity can be used to power our homes and businesses, and it can also be stored in batteries for later use.
And because solar power comes from the sun, it’s free once you’ve installed the photovoltaic cells. That means solar power is not only good for the environment, but it’s also good for your savings.
What Other Household Items Can You Make a Solar Panel With?
Solar power is the best energy source because it is clean, renewable, and free. Solar power does not produce any harmful emissions, so it is good for the environment. Additionally, solar power can be used to generate electricity, heat water, or even cook food.
In addition to CDs, you can also make a solar panel with items like aluminum cans, plastic bottles, and even egg cartons. These materials can be used to create a solar cell, which can then be used to generate electricity.
Frequently Asked Questions (FAQs)
Here are some frequently asked questions when it comes to making a solar CD.
What if my solar cell doesn’t work?
There are a few things you can try if your solar cell isn’t working:
- Make sure the CD is scratched evenly and in a straight line.
- Check to see if the CD is blackened in the scratched areas. Make sure the alligator clip wires are connected to the right sides of the CD (red to blackened, black to non-blackened).
- Ensure that the alligator clip wires are securely taped in place.
Can I use a different type of CD?
Yes, you can use a different type of CD, but keep in mind that not all CDs are created equal. Some types of CDs may work better than others.
What is the best way to store my solar cell?
When not in use, it’s best to store your solar cell in a cool, dry place.
What are some other uses for a solar cell?
Solar cells can be used to power small electronic devices, like calculators or watches. They can also be used to light up a dark space, like a closet or shed.
Do I need to buy anything else to make a solar cell?
All you need is a CD, a knife or razor blade, a black sharpie, some tape, and two alligator clip wires.
If you’re looking for a fun and easy science project, why not try making a solar cell from a CD? It’s a great way to learn about solar energy and how it works. Plus, it’s a great way to reuse an old CD that you would otherwise throw away.
Once your solar cell is complete, place it in direct sunlight and watch as it generates electricity. You can use this electricity to power a small fan or even a light bulb.
Go ahead and give it a try – you may be surprised at how much power your little solar cell can generate.
