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 is the difference between polysilicon and monocrystalline silicon photovoltaic cells?
Monocrystalline silicon cells with high battery conversion efficiency, good stability, but the higher cost. Polycrystalline silicon cells are less costly and slightly lower in conversion efficiency than straight-drawn monocrystalline silicon solar cells, with various defects in materials such as grain boundaries, dislocations, microdefections, and impurity carbon and oxygen in materials, as well as tarnished during process Transition metal.
Q:I studied very hard at school, but I just can not figure out how solar cells work, anybody can help me with that?
It's not a easy job.
Q:What diode does the solar panel use?
Or part of the shadow to the battery in the anti-output and power consumption according to the known solar modules suitable for the voltage range. Are in the Schottky diode conduction
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?
This is what I search online from Wikipedia, solar cell is an electrical device that converts the energy of light directly into electricity by the photovoltaic effect.
Q:Where can I help my company to buy the 3 Busbar Solar Cell for our project?
We are a solar cell company based in China, and we are actually promoting our product on alibaba, where you can find the TP-125M 6.5''x6.5'' 3-busbar solar cell be your choice.
Q:Where can I buy solar cells on sale but still good quality ?
Sometimes you can find a good deal with the local manufacturers, where they sell some good quality solar cells at a pretty good price.
Q:Does the solar cell generate electricity in the absence of the sun, only in the case of strong lights or lasers? If you can achieve how much, and the same day?
One of the directions for the development of modern solar cells is to maximize the frequency range of the light waves that can be energized (to the low frequency direction) to increase the power generation efficiency of solar cells.
Q:What is the pollution of solar cells?
the city warehouse classification storage; 5, centralized custody, waiting for the introduction of domestic waste battery recycling technology; 6, increase the size of the battery recycling; 2, regular hand-site acquisition; 3, battery classification (ordinary battery, button batteries)
Q:Where can I get the most accurate information about solar cells?
Don't trust whatever you search online, trust the book.
Q:Where can I buy solar cells?
Actually you can rent one, no need to buy one.
