As of 2007,
* commercial amorphous Si solar cells convert about 8% of the solar energy that strikes them into electrical energy.
* multicrystalline Si solar cells convert around 16% of the solar energy that strikes them into electrical energy
* commercial single crystal Si solar cells convert about 22% of the solar energy that strikes them into electrical energy.
So single crystal Si solar cells have the highest energy conversion efficiency.
However, amorphous Si solar cells require less energy to produce and are less expensive than multicrystalline Si solar cells, which in turn require less energy to produce and are less expensive than single crystal Si solar cells.
In some cases amorphous Si solar cells are more economically efficient (produce more power for the same initial price or initial investment in energy to produce).

What is the most common material used for a photovolatic solar cell?
The most command material used in photovoltaic solar cells is crystalline silicon.
What are the differences between crystalline and amorphous compounds or elements?
Elements themselves are not crystalline or amorphous. Instead this describes the structure of certain elements and compounds in the solid state. For instance, a single element can be found in both a crystalline form as well as an amorphous form. A crystalline solid is one in which there is a regular repeating pattern in the structure, or in other words, there is long-range order. In fact, you can completely describe the entire crystal by describing the single "repeat unit." For instance, as a simple example, if I have the pattern ABCABCABCABCABC... (that repeats infinitely) I can completely describe it by just saying it is "ABC" over and over again. In a 3-dimensional crystal, this repeat unit is called the "unit cell." Some crystalline solids are diamond, table salt, and many types of minerals found in the earth. An amorphous solid is one which does not have long-range order. In other words, there is no repeat unit. To contrast the example above, it would now be: ABCBCABBCACBACBAC... where there is no way to figure out what will be the next letter. Some examples of amorphous solids are glass (in windows, for example), wax, and plastics. If a liquid cools very quickly, the molecules will not have time to arrange themselves in the most favorable pattern (which will almost always be crystalline), and so they are locked into a disordered solid. Silicon is a common solid that can be found in both amorphous and crystalline forms, depending on how it is manufactured. Crystalline silicon is much harder to grow, but it is what is used in computer chips. Amorphous silicon is much cheaper and easier to grow, and is commonly used in solar panels.
What are the ways of making a solar cell?
Solar cells are typically made using crystalline silicon, which involves growing, slicing, and doping silicon wafers into photovoltaic cells. Another method is thin-film solar cell production, which involves depositing layers of semiconductor materials onto a substrate. Both methods require precise manufacturing processes to create efficient solar cells for converting sunlight into electricity.
What are the most efficient solar panels?
The most powerful solar panel is the Sunpower Turnkey Solar Solution. If you are thinking of getting this, think again. This effiecient Solar Panel is only built for busieness and Government buildings.
Materials of solar power?
In a crystalline solar electric panel, the light of the sun interacts with a semiconductor material (usually silicon) in the PV cell to free electrons and produce an electric current.
How are solar panels made?
Solar panels are made by cutting crystalline silicon into thin disks. Then dopants and metal conductors are spread across the surface. These disks are aligned on a solar panel making them ready for use.
Why is Silicon used in solar cell?
silicon(crystalline) is a semiconducting material that enables photoelectric effect to occur within the cell.it converts solar energy to electricity at a high speed.hence it is more efficient than any other material and produces large amount of electrical energy.

What does the solar cell do in space?
The function of solar cell is to convert the energy from the sun into electricity. This is commonly referred to as a photovoltaic cell.
How do you make a solar cell on little alchemy?
metal + human = tool tool + sun = solar cell sun + solar cell = electricity
What does copper used in solar panels?
Copper is an extremely efficient conductor of electricity with very low resistance. It virtually eliminates the loss of voltage/amperage when the electricity from the solar cell is being transferred to a battery or the power grid.
What is a solar cell?
A solar cell is an electronic device that converts sunlight into electricity. An array of them is called a solar panel.
