Overview of the Process

It’s quite a journey to make a solar cell at home. First, you take titanium dioxide out of powdered donuts. Then, you mix it to make a solution, and put it on conductive glass. Finally, you put everything together to make a solar cell. Doing this is a hands-on way to learn about renewable energy. It’s a fulfilling project for those who love the idea of living sustainably.

Gathering Materials

To make a solar cell at home, start with a few important materials. The first thing you’ll need is powdered donuts. They have a chemical, titanium dioxide (TiO2), that’s key for the solar cell.

Powdered Donuts as a Source of Titanium Dioxide

Powdered donuts might surprise you as a good source of titanium dioxide. This compound is important for the solar cell’s job of trapping light. By using the TiO2 from these treats, you can make a solar cell inexpensively.

Ethanol or Vodka for Solvent

For the powdered donuts, you also need a solvent to mix with the titanium dioxide. Ethanol or vodka works well for this job. They are affordable options for many people to use at home.

Conductive Glass or Indium Tin Oxide Coating

Lastly, you need conductive glass or glass coated with indium tin oxide (ITO). This layer is the foundation of the solar cell. It helps capture and use the electricity it produces.

Using these materials, your homemade solar cell can power devices. It’s a step towards a greener future.

Extracting Titanium Dioxide

Titanium dioxide in powdered donuts isn’t pure. It’s mixed with sugars and fats. To get the titanium dioxide, dissolve the sugar first.

Stir the powder into warm water. Then, pour it through a filter, like a coffee filter. The sugar will dissolve and flow through the filter. What’s left is the titanium dioxide and fats.

Dissolving and Filtering Sugar

Put the powdered donut mix in a glass of warm water. Mix it well until the sugar is gone. Now, pour this mix through a coffee filter.

The sugar-rich liquid will go through, but the titanium dioxide and fats stay. You are now ready to get the pure titanium dioxide.

Removing Fats through Baking

After separating the sugar, the fats need to go. Spread the mix on a baking sheet. Then, heat it in an oven at 200°C (400°F) for 30 minutes.

This baking step will remove the fats. What’s left is the titanium dioxide. It’s pure and ready to go into your solar cell.

Preparing the Titanium Dioxide Solution

First, mix the titanium dioxide powder with ethanol or vodka. Use a glass beaker for this. Add the powder to the beaker, then pour in the ethanol. Use 1 milliliter of ethanol for each donut. Finally, stir or shake the mix well.

Mixing Titanium Dioxide with Ethanol

After you get the titanium dioxide from the donuts, it’s time to make the coating solution. This mixture will help coat the glass used in making solar cells. To make it, just mix the powder with a liquid like ethanol or vodka.

Put the titanium dioxide in a clean beaker or container. For every donut worth of powder, add 1 milliliter of ethanol or vodka. Then, mix everything up really well to evenly spread the powder in the liquid.

Now you have the titanium dioxide solution. This solution is crucial for the next step, covering the glass. This creates the layer that turns sunlight into electricity in the solar cell.

Coating the Conductive Glass

To coat conductive glass, follow these key steps. Start by taping three sides of the glass. This ensures the coating is applied evenly. Then, use a dropper to add a bit of titanium dioxide solution.

Layering the Titanium Dioxide Solution

Once the glass has the solution, scrape off extra liquid with a microscope slide. Do this carefully ten times to form ten thin layers. This way, you create a smooth and solid coating on the glass.

Heating and Cooking the Cell

Next, heat up the coated glass to make the solution stick well. Put it in an oven set to 450°F (230°C) for 30 minutes. Watch closely to avoid harming the glass or its coating.

how to create solar cell at home

Enhancing the solar cell’s light-capturing ability is easy. Just stain it with tea. Teas contain anthocyanins that are great at catching light. Use a cup of hibiscus tea and soak the cell in it for a few hours. The anthocyanins will stick to the cell’s surface. This lets the cell catch more light, including the visible kind, not just UV light.

Staining the Cell with Tea

Soaking the solar cell in tea is a simple yet effective step. Teas have anthocyanins, which catch light in the visible range. A cup of hibiscus tea can work well for this. Just leave the cell in the tea for a while. The anthocyanins will attach to the cell, helping it catch more light.

Creating the Counter-Electrode with Graphite

For the counter-electrode, you’ll need graphite. Graphite helps pass the solar cell’s electrons to the outside circuit. You can use a pencil lead or get graphite powder. Put a thin layer of graphite on one side of the conductive glass. This glass is for the counter-electrode.

Assembling the Solar Cell

First, create a spacer between two glass pieces. You can use a thin plastic spacer or put tape around the edges on the clean side of each glass. This keeps the plates apart a bit.

Spacing the Glass Plates

The spacer avoids direct contact of the glass plates. This lets you add the electrolyte solution between them. The space is important for the cell to work right. It helps with the electron flow and making an electrical current.

Adding the Electrolyte Solution

Once the glass plates have a space, add the electrolyte solution. This solution helps with the electron transfer. Pour it carefully between the glass plates. Make sure it covers the whole surface.

Pressing and Securing the Cell

Press the glass plates gently together. This makes the electrolyte solution spread evenly. Next, use clamps or adhesive on the edges. This stops leaks and keeps the solar cell strong.
