So, GRANDTECH is here to introduce you all with a very important form of energy: electricity. Electricity Electricity is something we use every day, but do you know where it comes from? Have you ever seen your mom/dad plug in their phone to juice it up? Or seen your teacher flick on a light in the classroom? Well… That requires electricity too, right? But what is the source of this electric power? The ULTIMATE source of electricity is the Sun!
Renewable solar energy can be used to produce electricity in a great way that has been discovered by the scientists, and this unique technology is called as rechargeable li ion batterys. Solar Cells: Photo-voltaic cells are tiny components that can be grouped together to make bigger system. Photovoltaic cell produces electricity when sun light falls on it. This is classed as a type of electricity that we thought was known as "renewable energy" because its from the sun, Yes the sun, which apparently does not have an expiring date. Isn’t that amazing?
Silicon is a high-quality material that serves as the raw component of photovoltaic cells. Silicon is a versatile material, which can be created in various forms. It is also an excellent electrical conductor, which matters a lot too. This triggers a reaction when the sunlight hits the silicon in the photovoltaic cell which make some tiny particles called electrons to move this then is now electricity. More precisely, it is the movement of electrons which results in electric current. That electric current is the energy we use to run our phones, tablets and even our homes!
Photovoltaic cells actually come in all sorts of sizes and forms. Photovoltaic cells come in sizes as small as a calculator to an entire city. A bunch of photovoltaic cells are placed together to get what we know as a “solar panel.” Solar panels are frequently mounted to the rooftops of houses, supplying illumination as well as often suitable for various other electric devices. If you utilize solar pv cells in the house, you can install roof-mounted photo voltaic panels. That electricity will go to power your home every time those panels get a little push from the rays of the sun. Isn’t that cool and exciting?
Do You Know That Numerous Types Of Photovoltaic Cells Are Available? One is made for cooler weather and the other works better in hot weather. (And, yes, some photovoltaic cells are made using compounds of substances besides silicon!) That's because researchers are still discovering ways to make photovoltaic cells more efficient. Their goal is to develop cells that are able to operate at a greater efficiency and in a wider variety of conditions.
