Making More Solar Cells from Silicon

Silicon wafers are the conventional solar cells–they’re what absorbs sunlight and generates electrons. Yet the way wafers are currently manufactured wastes half of the expensive, ultra-pure crystalline silicon they’re made from. When large ingots of silicon are cut into hair-thin wafers, waste silicon is lost as sawdust. The new process–details of which remain secret–produces wafers directly from molten silicon without any sawing. This saves material and reduces the number of steps needed to make solar cells, both of which bring down costs.

How to Grow "Silicon" Crystals to Make Solar Cells

In industry, silicon crystals are grown to form a uniform cylinder of silicon which is used as the base material for crystalline solar cells. There is plenty of silicon about on the earth, in fact, as mentioned previously, after oxygen it is the second most abundant element. When you think that sand and quartz all contain silicon and then imagine the amount of sand in the world, you begin to realize that we are not going to run out of silicon in a hurry!

The problem with sand is that it also contains oxygen in the form of silicon dioxide, which must be removed.

The industrial process used to produce silicon requires temperatures of around 3270oF (which is about 1800oC). Obviously we can't experiment with these3 sorts of temperatures at home - but we can recreate the process!

You are going to need a saturated sugar solution; this will sit in the lid of your coffee jar. Now, take a large crystal of sugar, often sold as "rock sugar" and "glue" it to the end of the skewer. Next, drill a hole the same diameter as the skewer, and poke the skewer through the bottom of the coffee jar. Stand it on a windowsill and lower the crystal into the saturated sugar solution. Over some time, crystals should start to grow - pull the skewer up slowly, bit by bit, so that the growing crystal is still in contact with the sugar solution. This is just like the way that silicon is grown. The silicon is drawn up slowly from a bath of molten hot silicon (which is analogous to our saturated sugar solution).

Once this large crystal of silicon has been manufactured, it must be cut into slices to manufacture the solar cells.

Q:What information can I get from the Internet about the solar cell modules? Such as what it is? How it is made?
A solar cell module has a chamber and includes a solar cell device, a gel /fluid, and a light-focusing unit. The solar cell modules are basically a group of solar cells used a specific function.
Q:What is the working principle of a solar cell?
A solar cell is a solid-state electrical device (p-n junction) that converts the energy of light directly into electricity (DC) using the photovoltaic effect.
Q:Is A grade better than the B grade when we buy the poly solar cells.
The poly solar cell with A grade means the sustainabilty and quality of the poly solar cells are better than the others.
Q:How can the huge solar cells be applied into the market?
If you are just using power supply for daily usage, such as a family of 6, you don’t need the huge solar cells.
Q:I studied very hard at school, but I just can not figure out how solar cells work, anybody can help me with that?
The principle of solar cells is quite difficult to understand.
Q:What is 3d solar cell? And anybody know any manufacturers?
3D’s solar cell is designed from the ground up to optimally reduce all primary losses to achieve the highest conversion efficiency.
Q:Are bulk solar cells better than the normal solar cells?
Bulk solar cells are not absolutely better than normal solar cells, it is decided by what kind of material.
Q:I am a purchasing manager for a EPC engineering company, and we are planning to purchasing some 4bb solar cells for one of our project in Taiwan, can I get a quotation online?
We are a professional company selling solar cells. Tomi Fuji is dedicated to provide high quality solar products, ranging from Photovoltaic (PV) cells, PV modules to PV power systems. You can trust us to get the best quality product with the best price.
Q:My son is very interested in solar cells recently, and keeps asking me about the structure of a solar cell. Can anybody help me answer that question?
As a newly-developed power generation technology, solar cells are considered to be an evironmental-protecting green energy
Q:What is a monocrystalline Silicon Solar Cells?
Compared to the other kinds of solar cells made in the world, the Monocrystalline Silicon Solar Cells are much more efficient and less cost-saving than the other kinds of solar cells.
