How to Make Solar Cell From Copper Sheet

Today, I’m going to write a post on How to Make Solar Cell from Copper sheet. This project is an old one, I did when I was in 10th standard. Since I’m planning to build a serious blog content, it is extremely useful if I share my experiences here. Then, why waste time.

You need two pieces of copper sheets. Similar in size. 4-6 inch in width. Then clean both surfaces of both copper plates throughly.

Steps to Make Solar Cell

Step 1: Firstly, You need two pieces of copper sheets. Similar in size. 4-6 inch in width. Then clean both surfaces of both copper plates throughly.

Step 2

Secondly place one of the copper plates on a hot plate. I suggest you to use a hot plate instead of gas stove to get perfect oxide layer on both surfaces of the copper plate.

Step 3

Thirdly, As the copper heats up you can see varying shades of red, pink, purple, and possibly other colors. This is a sign that oxidation is taking place. Oh Great! But, be very careful with it.

Step 4: When you finish cooking the copper, turn the burner off. Leave the copper on the burner to cool. This allows the copper to cool very slowly. The semiconductor is ready.

Step 5: Prepare An effective electrolyte solution from 1:3 salt to water ratio. Now, place the two copper plates into the container. One is oxidized and other is clean copper. Place the container in sunlight and connect alligator clips to each copper sheets.

Step 6 : Finally, Connect the copper sheet with cuprous oxide layer to the clip that will lead to the positive terminal of the multimeter. And the clean copper sheet should be connected to the negative terminal.

Step 7: In conclusion, When the sunlight hits the cuprous oxide layer, it causes electrons to be released. The cuprous oxide is not conductive, but the electrons are able to move through the salt water to the conductive copper plate. This plate transfers the electrons to the wires. Most importantly Don’t forget to Set your meter to read microamps. Now you can see A very small amount of current flowing through the multimeter.
