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:Can solar cells be used to power agricultural irrigation systems?: Yes, solar cells can be used to power agricultural irrigation systems. Solar panels can convert sunlight into electricity, which can be used to power pumps and other equipment necessary for irrigation. This renewable energy source can provide a sustainable and cost-effective solution for powering irrigation systems in remote or off-grid areas.

Q:What do the solar cell suppliers provide once we purchase the order from the solar cells from them.: The good solar cells suppliers do not only sell you the solar cells products, they also give you very useful suggestions to help you install it.

Q:Can solar cells be used in electric fence systems?: Yes, solar cells can be used in electric fence systems. Solar panels can generate electricity from sunlight, which can then be stored in batteries and used to power electric fences. This eliminates the need for a connection to the main power grid and makes electric fence systems more flexible and cost-effective in remote areas.

Q:How does the size of a solar cell affect its performance?: The size of a solar cell directly affects its performance. Generally, larger solar cells can generate more electricity as they have a larger surface area to collect sunlight. This means they can absorb more photons and convert them into electrical energy. Additionally, larger solar cells tend to have lower resistance and better efficiency. However, larger cells also require more materials and are more expensive to produce. Therefore, the optimal size of a solar cell depends on various factors, including the available space, budget, and desired energy output.

Q:Can solar cells be damaged by hail or other weather events?: Yes, solar cells can be damaged by hail or other severe weather events. Hailstones can potentially crack or shatter the surface of the solar panels, affecting their efficiency and functionality. Similarly, extreme weather events like hurricanes or heavy storms can cause physical damage by dislodging or breaking the panels, leading to a decrease in their performance. It is important to ensure proper installation and maintenance to minimize the risk of weather-related damage to solar cells.

Q:Can solar cells be used in indoor applications?: Yes, solar cells can be used in indoor applications. While solar cells primarily generate electricity from sunlight, they can also convert artificial light sources, such as fluorescent or LED lighting, into electricity. This makes them suitable for powering various indoor devices and applications, including calculators, wireless sensors, and even indoor lighting systems.

Q:How does the photovoltaic cells work?: Photovoltaic solar cells fulfill two functions: photogeneration of charge carriers (electrons and holes) in a light-absorbing material, and separation of the charge carriers to a conductive contact that will transmit the electricity.

Q:Can solar cells be used in aircraft applications?: Yes, solar cells can be used in aircraft applications. Solar cells have been integrated into various aircraft designs, including drones and solar-powered airplanes. They are used to capture sunlight and convert it into electricity, which can be used to power the aircraft's electrical systems or recharge its batteries. Solar cells offer a renewable and sustainable source of energy, reducing the reliance on traditional fossil fuels and making aircraft more environmentally friendly.

Q:What is the maintenance required for solar cells?: The maintenance required for solar cells is typically minimal. It involves regular cleaning of the solar panels to remove any dust or debris that may accumulate and potentially reduce their efficiency. Additionally, periodic inspections are recommended to detect any signs of damage or wear, such as cracked glass or loose connections, which should be repaired promptly. Overall, proper maintenance ensures optimal performance and longevity of solar cells.

Q:Can solar cells be used to power refrigeration systems?: Yes, solar cells can be used to power refrigeration systems. Solar cells convert sunlight into electricity, which can then be used to power various appliances, including refrigeration systems. This is particularly useful in off-grid or remote areas where access to conventional power sources may be limited.
