There are  a variety of numerous technologies which you can use to make devices which  convert light into electricity, and we're going to explore these subsequently.  There's always an account balance to become struck between how good something  works, and how much it costs to produce, along with the same goes for solar  energy.
We take cells, and that we combine them into larger units generally  known as "modules," these modules," these modules can again get in touch  together to make arrays. Thus we could see that there's a hierarchy, the  location where the solar panel may be the smallest part.
Why don't we look  into the structure and properties of solar "cells," but bear in mind, when  combined into modules and arrays, the solar "cells" here are mechanically backed  up by other materials-aluminum, glass, and plastic.
One of many materials  that solar cells can be created from is silicon-this will be the material which  you find inside integrated circuits and transistors. You will find great reasons  for utilizing silicon; it's the next most abundant element on this planet after  oxygen. If you think about that sand is silicon dioxide (SiO2), it becomes clear  that there's a lot than it out there!
Silicon can be utilized in many  different ways to produce solar cells. The most beneficial solar panel  technology is that of "monocrystalline cells," these are generally slices of  silicon extracted from just one, large silicon crystal. As it is an individual  crystal it has a very regular structure no boundaries between crystal grains and  so it performs perfectly. Stop identity a monocrystalline solar cell, since it  definitely seems to be round or even a square with rounded corners.

Among the caveats with this type of method, since you will see  later, is that whenever a silicon crystal is "grown," it makes a round  cross-section solar cell, which will not fit well with making solar panel  systems, as round cells take time and effort to set up efficiently. Another type  of solar panel we are taking a look at also made from silicon, is slightly  different, it's a "polycrystalline" solar cell. Polycrystalline cells continue  to be made out of solid silicon; however, the procedure accustomed to make the  silicon from where cellular matrix are cut is slightly different. This brings  about "square" solar panels. However, there are many "crystals" inside a  polycrystalline cell, in order that they perform slightly less efficiently, even  though they are cheaper to create with less wastage.Now, the challenge with  silicon solar cells, as we might find over the following experiment, is that  they are common effectively "batch produced" which means these are produced 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,  this means they are very costly.
Now, there is certainly another type of  solar panels, so-called "thin-film" solar cells. The real difference between  these and crystalline cells is the fact that instead of using crystalline  silicon, these use substances to semiconduct. The chemical compounds are  deposited together with a "substrate," in other words a base to the solar cell.  There are many formulations that will not require silicon in any way, such as  Copper indium diselenide (CIS) and cadmium telluride. However, there's also a  process called "amorphous silicon," where silicon is deposited over a substrate,  however, not in a uniform crystal structure, but because a skinny film.  Furthermore, instead of being slow to produce, thin-film solar panels can be  achieved using a continuous process, making them much cheaper.
However, the  disadvantage is the fact that when they are cheaper, thin-film cells are less  efficient than their crystalline counterparts.
