Gathering the Required Materials

Do you want to make a homemade solar cell? Start by getting a few key items. The first one might surprise you – it’s powdered donuts. The powder in donuts has a chemical called titanium dioxide. This chemical is important for making the solar cell.

Powdered Donuts

The donuts’ powder provides titanium dioxide for the solar cell. This chemical helps the cell turn sunlight into energy.

Ethanol

Besides donuts, you need ethanol. The purest kind is best. Lab-grade two hundred proof ethanol is perfect. But, if you can’t find it, you can use strong alcohol like vodka. This ethanol is for the solution that goes on the glass.

Hotplate

A hotplate is crucial for this project. It’s used after the solution is on the glass. The hotplate will help cook the solar cell. This process removes what’s not needed and finishes the cell.

Conductive Glass

Also, you’ll need conductive glass. It has a special coating, such as indium tin oxide. This glass lets electricity pass through. Without it, the solar cell can’t work.

Now you have what you need to start. Get ready to make your solar cell. Fenice Energy can help with solar, backup systems, and EV charging. They have over 20 years of experience.

Extracting Titanium Dioxide from Powdered Donuts

Titanium dioxide from powdered donuts mixes with sugar and fats. To get rid of the sugar, add the powder to warm water. Then, pour it through a filter, like a coffee filter. Sugar dissolves in the water, going through the filter. This leaves titanium dioxide and fats behind.

Dissolving the Sugar

Add the powder to warm water and pour it through a coffee filter. The sugar dissolves in the water and passes through. What remains is a mix of titanium dioxide and fats.

Removing the Fat

Fats don’t dissolve in water, staying with the titanium dioxide. To take out the fats, bake the powder at 500°F (260°C) for about three hours. This step vaporizes the fats, giving us pure titanium dioxide powder.

Creating the Titanium Dioxide Solution

To make the titanium dioxide solution, mix the pure powder with ethanol in a glass beaker. Use about one milliliter of ethanol for each donut. Stir the mixture well. This titanium dioxide solution is crucial for coating the conductive glass.

We mix and stir to spread the titanium dioxide particles evenly in the ethanol. This creates a smooth solution. It’s the first step in making the solar cell. This prepares us for the rest of the DIY project.

First, the titanium dioxide solution is used to coat conductive glass. Drop a small bit of the solution on the glass with a dropper. Then, use a microscope slide to remove extra liquid. You’ll repeat this step at least ten times to add more layers.

Cooking the Solar Cell

Next, put the coated glass in a clear and heatproof beaker or dish. Place it on a hotplate. Cook it for 10-20 minutes until it changes from brown back to white. This shows the organic solvents have burned off and it’s done heating.

Staining with Tea

Now, let’s add some color. Teas have a compound called anthocyanins that capture light well. Submerge the solar cell in herbal tea, like hibiscus, for a few hours. This stains the cell and helps it catch more visible light along with UV light.

Assembling the Solar Cell Components

To make a homemade silicon solar cell, we need to set up the counter-electrode and put all the parts together. Conductive glass, graphite, an iodine-based electrolyte solution, and a few tools are needed. These items help in making the solar cell.

Preparing the Counter-Electrode

Start with a conductive glass, like indium tin oxide (ITO) or fluoride-doped tin oxide (FTO) coated glass. Use a regular graphite pencil to put a layer of graphite on the glass. This coated glass becomes the solar cell’s counter-electrode.

Adding the Electrolyte Solution

Mix iodine with alcohol in a 3:1 ratio to make the electrolyte solution. This solution lets the electrons move from one electrode to another. After mixing it, drop one to two drops of the solution between the glass pieces. Make sure it spreads out evenly.

Connecting the Electrodes

Press the two glass pieces, with the titanium dioxide-coated slide and the graphite-coated slide, together. Do this before the electrolyte dries. To keep everything in place, secure them with alligator clips. This action completes the solar cell.

Conclusion

This DIY guide has shown you how to make a solar cell at home with simple steps. You can do it using items that are easy to find. You start by taking titanium dioxide from powdered donuts and making a special mixture. Then, you put this mixture on glass and add some other parts. This project is a fun way to learn about new energy and to be creative with sustainable ideas.

FAQ

What materials are needed to make a silicon solar cell at home?

You will need powdered donuts, ethanol, a hotplate, and conductive glass. The glass should be coated with indium tin oxide (ITO) or fluoride-doped tin oxide (FTO).

How do you extract titanium dioxide from the powdered donuts?

First, mix the powdered donuts with warm water. Then, pour the mixture through a filter like a coffee filter. The sugar will dissolve in the water. This leaves just the titanium dioxide and fats. Next, bake the powder at 500°F (260°C) for about three hours to remove the fats.

How do you create the titanium dioxide solution?

Mix the pure titanium dioxide powder with ethanol in a glass beaker. Stir it well. Use about one milliliter of ethanol per donut.

How do you coat the conductive glass with the titanium dioxide solution?

Drop the titanium dioxide solution onto the conductive glass. You can use a dropper or pipette for this. Then, use a microscope slide to remove any extra liquid. This leaves a thin coating. Repeat this step ten times to make many layers of titanium dioxide on the glass.

How do you assemble the complete solar cell?

Coat another piece of conductive glass with graphite using a regular graphite pencil. This piece will be the counter-electrode. Use an iodine solution as the electrolyte. Then, press the two glass pieces together before the electrolyte dries. You can use alligator clips to keep them in place. This creates your full solar cell.
