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.
