Materials Needed

You’ll need some everyday items to make a model solar cell at home. Most notably, look for powdered donuts. They have titanium dioxide (TiO2) inside, a crucial ingredient. You’ll also need ethanol or vodka to mix with the TiO2. For the electrodes, use conductive glass slides. Plus, a graphite pencil is perfect for the counter-electrode. Finally, add iodine solution to act as the electrolyte. With these materials, you’re all set to create a tiny but functional solar cell.

Donuts and Powdered Sugar

Did you know powdered donuts have titanium dioxide in them? This white powder is perfect for the solar cell’s key component. Just extract the TiO2 from the donuts. Then, use it to cover the glass slides.

Ethanol or Vodka

A solvent like ethanol or vodka is crucial for this process. These alcohols help dissolve the titanium dioxide powder from the donuts. You can then apply this solution to the glass slides.

Conductive Glass Slides

You need two conductive glass slides for the solar cell. They will act as the positive and negative electrodes. Make sure to cover them with the titanium dioxide solution and graphite.

Graphite Pencil

For the counter-electrode, a simple graphite pencil is all you need. Drawing with the pencil on one of the glass slides will do the trick. This drawing helps to complete the circuit.

Iodine Solution

For the final step, add an iodine solution. This will serve as the electrolyte within the solar cell. Add it between the glass slides. This step is vital for the cell to work.

These materials are all you need to start a fun and educational science project. With them, you’ll make a real model solar cell. You’ll also learn about how solar energy works. Fenice Energy is here to provide all your clean energy needs. They have more than 20 years of experience in solar, backup systems, and electric vehicle charging.

Extracting Titanium Dioxide

The first step in making a solar cell is to get the titanium dioxide. We take it from the powdered donuts. This special ingredient is crucial for the photoanode of the DIY solar panel you’re making.

Dissolving Sugar from Donut Powder

Dissolve the sugar in warm water to begin. Then, filter the mix to get rid of the solid part. This way, we separate the titanium dioxide from the fats found in the donut powder.

Removing Fats by Baking

After filtering, bake the powder at 500°F (260°C) for three hours. This step gets rid of the fats. Then, you have a clean titanium dioxide powder ready for the photovoltaic cell in your homemade solar energy project.

Start by mixing titanium dioxide powder with ethanol. Use titanium dioxide from powdered donuts. This mix becomes a solution for the glass.

Coating Glass with Titanium Dioxide Solution

Put 10 even layers of the solution onto a piece of conductive glass. Coating the glass with titanium dioxide is very important. It’s what turns light into power.

Heat Treatment of Coated Glass

After coating, heat the glass to remove solvents. This makes the glass stable and the solar cell more efficient.

Staining with Anthocyanin Dye

Next, stain the glass with anthocyanin dye made from berries. This dye attracts light and makes the solar cell produce more power.

Now, the glass is ready to act as the positive part, the photoanode, of the solar cell.

Assembling the Solar Cell

To make the solar cell, first, prepare the counter-electrode. Then, add the electrolyte solution. Finally, sandwich the electrodes. This creates a solar cell that makes a bit of electrical current from light.

Preparing the Counter Electrode

Coat a piece of conductive glass with graphite from a pencil. This graphite layer becomes the counter-electrode. It helps the solar cell work by connecting with the dyed photoanode.

Adding Electrolyte Solution

After that, add iodide electrolyte drops to the titanium dioxide slide. This electrolyte is key. It lets electrons move between electrodes, making the solar cell produce electricity.

Sandwiching the Electrodes

Sandwich the two electrodes together. Make sure the graphite is against the titanium dioxide. Use binder clips to keep everything tight. This ‘sandwich’ turns light into electric power in your solar cell.

Conclusion

By following simple steps, a working model of a solar cell was created using everyday items. This project helps you learn about photovoltaic technology and solar cell construction.
