There are a variety of different technologies you can use to generate devices which convert light into electricity, and we are gonna explore these subsequently. There is always an equilibrium being struck between just how well something works, and how much it is to produce, along with the same goes for solar panel technology.
We take cells, and we combine them into larger units known as "modules," these modules," these modules can again link together to form arrays. Thus we can easily note that there’s a hierarchy, the place that the solar panel could be the smallest part.
Why don’t we check out the structure and properties of solar "cells," but remember, when combined into modules and arrays, the solar "cells" here are mechanically based on other materials-aluminum, glass, and plastic.
One of several materials that cells can be created from is silicon-this will be the material which you find inside integrated circuits and transistors. You’ll find great reasons for using silicon; it is the next most abundant element on this planet after oxygen. Considering that sand is silicon dioxide (SiO2), you realize that there is lots of it around!
Silicon can be utilized in many different ways to produce pv cells. The best solar panel technology belongs to "monocrystalline solar cells," they are slices of silicon obtained from an individual, large silicon crystal. As it is a single crystal it features a very regular structure with no boundaries between crystal grains so it performs adequately. Stop identity a monocrystalline solar panel, since it definitely seems to be round or possibly a square with rounded corners.
One of many caveats with this type of method, because you will see later, is every time a silicon crystal is "grown," it produces a round cross-section solar panel, which will not fit well with making solar panel systems, as round cells are hard to prepare efficiently. The following kind of solar cell i will be investigating also made out of silicon, is slightly different, it’s a "polycrystalline" solar panel. Polycrystalline cells are still made out of solid silicon; however, the task accustomed to make the silicon from where the cells are cut is slightly different. This ends in "square" solar panels. However, there are numerous "crystals" in the polycrystalline cell, so that they perform slightly less efficiently, although they are less costly to generate with less wastage.
Now, the situation with silicon cells, even as we will discover next experiment, is because they are all effectively "batch produced" which suggests they’re stated in small quantities, and are fairly expensive to manufacture. Also, as many of these cells are formed from "slices" of silicon, they’ll use a lot of material, meaning they’re fairly dear.
Now, there is a different type of solar panels, so-called "thin-film" solar panels. The difference between these and crystalline cells is the fact that as an alternative to using crystalline silicon, these use chemical substances to semiconduct. The chemical compounds are deposited along with a "substrate," frankly a base for the solar cell. There are many formulations that won’t require silicon at all, for example Copper indium diselenide (CIS) and cadmium telluride. However, there is also a process called "amorphous silicon," where silicon is deposited on a substrate, however, not within a uniform crystal structure, but because a skinny film. In addition, instead of being slow to generate, thin-film solar panels can be done using a continuous process, causing them to be much cheaper.
However, the disadvantage is the fact that when they are cheaper, thin-film solar cells are less capable than their crystalline counterparts.
