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:Where and how can we find the best solar cells suppliers?
I used to be a solar cells business dealer in the European market for over ten years, and I did not only use the internet to find the supplier, but also go to a lot solar cells industrial exhibition fairs.
Q:Can the solar powered cells really work better than the normal cells?
There is no doubt that the solar powered cells work better than the normal cells, the only disadvantage is the cost of making it.
Q:Can solar panels be charged with light?
Since the output power of solar modules depends on factors such as solar irradiance and solar cell temperature, it is not recommended to use light charging, efficiency is not only very low, and also meaningless.
Q:How many years should I spend in the solar cell industry to be a good solar cells sales person?
Experience matter, but not the years. As long as you are learning the solar cells knowledge everyday, you can be a good solar cells sales in just one year.
Q:How long does it take to make a solar cell?
If you decide to make it by yourself, it will take you very long.
Q:What diode does the solar panel use?
Species, then the impact of ordinary diode voltage drop will be relatively large, but if the voltage is relatively high, then 0.3V gap relative impact is relatively small.
Q:What is the window material in the solar cell? what's the effect?
The meaning of the window layer with his Chinese meaning is the same, referring to the first solar cells to accept the light.
Q:What is the solar cell production process
Solar cells are the core devices in the PV power generation system. Energy saving is a kind of device that uses the principle of photoelectric conversion to convert the radiated light of the sun into electrical energy through the semiconductor material. This photoelectric conversion process is usually called "photovoltaic effect", so the sun
Q:What is a High-efficiency electric solar cell panel?
A highly efficient electrical solar cell should meet such requirements: High-efficiency silicon battery guarantee steady and persistent output power.
Q:Is the Photovoltaic Cells cheap to buy?
Photovoltaic Cells is cheaper than some kinds of solar cells because of the material that made of the Photovoltaic Cells is low cost one.
