It’s a common question I get from the inquisitive: “How do solar panels work?” It’s a hard question to answer in limited time, but I’ll do my best here.
Typically a 250w solar panel is made up of 60 cells, each cell measures about 150mm. The working of these individual cells is the basic explanation of how a solar panel works.
The PV cells consist of Silicon, which is a semiconductor. Silicon itself does not create electricity, so a bunch of Chemists and Physicists came up with an ingenious idea. They cut the silicon into two thin layers and “doped” the silicone with impurities. They added the element Phosphorous one layer and Boron into the other. When doped with Phosphorous, the resulting silicon is called N-type (“n” for negative) because of the abundance of free electrons. The other piece of Silicon, doped with the Boron, becomes a P-type Silicon (“p” for positive). Instead of ha
