How Are Solar Cells Made?
In one of my recent home projects, I’ve been making my own solar panels. I buy the cells by the hundreds, and yet they still come in a small package. I use the 3 x 6 inch cells that are thinner than a credit card, and I wondered to myself how they make these solar cells? I decided to do some research and came up with “how solar cells are made.”
A solar cell is a device that collects energy from the sun and converts it into electricity. She used to be called multiple solar panels and solar panels. Sometimes referred to as a solar cell photovoltaic cell. They were discovered by Alexander Bequerel 1839.
- Photo cells can be made from three different types Crystals- Three types of cells are now used to create contemporary photovoltaic cell; mono-crystalline, polycrystalline and amorphous. They are all based on silicon, which is a widely used semi-conductor, plus one of the most common elements of the earth. Processing of silicone does not have any impact on the environment in any way.
- In the making of a cell is “doping” referred to as – Doping is a term used to describe the addition of a chemical element that, when added can be either a positive charge (p) or negative (n) cost to produce. When these two layers are combined, an n-semiconductor layer and a p-semiconductor layer, is now what is known as a pn junction. Is then added to silver so that it can be electrically connected.
- The solar cells are manufactured- The most cost effective process includes type polycrystalline cell. This process is done by pouring liquid silicone into blocks or desired form, after hardening, cut into thin layers called plates. A monocrystalline producing cell type, is used a pure semiconductor silicon. Of the molten silicon, rods are formed, and then cut into thin sheets. This process usually has the highest efficiency of production. A thin layered cell referred to as amorphous; by depositing either on glass or another stronger material, the thickness thereof, the thickness of a human hair. This is a very low efficiency cell does to the loss of material during the manufacturing process. These are usually used in low-end applications, such as watches, calculators, and kids toys.
- New ontwikkelingen- With new production, solar cells are now part of a gravel roof or in a roll. These solar cells at the moment are quite expensive, but if demand increases, I am convinced that the cost factor will also change.
With the demand for solar cells on the rise, new developments will continue. Keep abreast of what is happening with the production of solar cells, and how you can build your own solar panels to keep, to visit Earth Power Energy Systems. Feel free to leave us comments or questions and I will try to answer.
