3 Types of Photovoltaic Solar Panels - What are the Differences?
The are 3 basic types of construction of Photovoltaic solar panels although all of these use silicon.
Monocrystalline cells are cut from a single crystal of silicon. They are basically a slice of crystal. This makes them very smooth in texture and you will can see the thickness of the slice. Monocrystalline cells are the most efficient, but also the most expensive to produce. They are completely rigid and must be mounted in a rigid frame for protection.
Polycrystalline (or Multicrystalline) cells are made from a slice cut from a block of silicon, but whereas Monocrystalline cells are from a single crystal, these cells consist of a large number of crystals. This gives them a speckled reflective appearance but, once again you can you see the thickness of the slice. Photovoltaic solar panels made from these types of cell are slightly less efficient but also slightly cheaper than monocrystalline cells. They also need to be mounted in a rigid frame.
Finally, amorphous cells are manufactured by placing a thin film of amorphous (non crystalline) silicon onto a wide range of surfaces. These create the least efficient type of Photovoltaic solar panels but also the cheapest. Due to the amorphous nature of the thin layer it is flexible, and if manufactured on a flexible surface, the whole photovoltaic solar panel can be flexible. One problem with amorphous cells, however, is that their power output reduces over time, particularly during the first few months, after which time they are basically stable. The quoted output of an amorphous panel should be that produced after this period.

What publicly traded companies only manufacture silicon, the basic material used to make photovoltaic solar modules?-
ANSWER:
Not to be a nitpicker, but silicon isn't manufactured by any company. It is a naturally occuring basic element with an atomic number of 14. Check the periodic table.Silicon is usually acquired in mass from commercial mining operations, then sent to, for instance, semiconductor companies that make the kind of modules you're interested in. You could conceivably look to invest either in the mining companies or in semiconductors. Before you do either, you should definitely educate yourself about both, and probably about the manufacturing chain between raw silicon and finished product. Here's a link to silicon on Wikipedia.

QUESTION:
Can I make my own Photovoltaic Solar Cell?
Others have asked if they can buy solar cells and build their own system, but I am interested in actually making the photovoltaic layer. Efficiency is not as important as simplicity; size is not particularly important either but I would like to light a bulb or turn a small motor. With a pane of glass, polyester film and some other basis ingredients, I sure would appreciate some help!-
ANSWER:
You can make your own cells but the efficiency is so horribly low you'll be lucky to register it on a voltmeter. Most people won't have the facilities to make and process silicon so you have to find some other materials.
