PV Gap

What equipment is needed to make a solar cell?

We Answered:

If you search the internet, you'll certainly find ways to make very low power solar cells from common materials, but I'll assume that you want to make one with significant output.

If you can somehow obtain solar grade wafers (or maybe you could just use the back of a regular semiconductor wafer if you can get one that's clean), then all you would need is a screen printer, the right chemicals, and a diffusion furnace. If you're at a university, and they have a semiconductor process lab, they may have all the stuff you need, already. A corporate lab (for example, at Agilent) would have this kind of stuff, too. If you wanted to do it at home, the cost would be prohibitive, and some dangerous materials would be involved.

How to make solar cell?

Here are instructions to make two different types of photovoltaic cells (“solar cells”),

Using conductive glass and Titanium Dioxide,

Using Copper,

In order to generate a significant amount of power, one will need to build very large versions of each of these cells. They will likely be impractical for large scale application, but they will work for demonstration purposes to show that yes you can successfully build a working solar cell.
