How to make a solar cell?

In order to make your own solar cell, you will need a collection of materials that you can source from basic electronic components stores or online. The primary material for your solar cell is silicon. It’s an abundant, non-toxic element that forms a great base for converting solar energy.

Should you DIY a solar cell?

Going the DIY route in creating your solar cell not only provides practical understanding and skills, it can also make solar power more accessible by bringing down costs, encouraging local enterprise, and fostering a sense of empowerment and accomplishment.

How does a solar cell work?

These wafers form the foundation of your solar cell. Doping involves adding a tiny amount of an element to the silicon to change its properties. Traditionally, boron and phosphorous are incorporated into the silicon to form the P/N junction necessary for a solar cell to function.

How does doping work in a solar cell?

Doping involves adding a tiny amount of an element to the silicon to change its properties. Traditionally, boron and phosphorous are incorporated into the silicon to form the P/N junction necessary for a solar cell to function. This junction is critical in the creation of an electric field within the cell.

How do you protect a solar cell from sunlight?

Put them together with conducting wires attached to positive and negative sides, then cover the cell to protect it from the environment. When sunlight hits your solar cell, it will generate an electric current. If playback doesn't begin shortly, try restarting your device.

Do solar cells need to be purified?

Silicon is a key ingredient in your solar cell, and it needs to be purified before use. This step generally involves heating the silicon in a vessel at high temperatures until impurities are removed. Silicon for solar cells needs to be single crystal, which means all the silicon atoms in the sample are perfectly aligned.
