If Physics amuses you, you must be knowing that photovoltaic (PV) cells are a phenomenal creation by man that have immensely contributed to saving global resources. In simple terms, photovoltaic cells are nothing but a cluster of cells put together, forming a solar panel, converting sunlight into electricity. Energy is created when the photons present in the sunlight take up electrons into a rather higher level of energy. Photovoltaic cells were first developed at the Bell Labs in mid-21st century, solely for applications associated with space. However, today, it is being used by all the leading science organizations, and even commoners who live in areas where sunlight is quite adequate for them to make effective usage of solar energy for homes. So, what are photovoltaic cells made of? How much is the Photovoltaic cells cost? What are the benefits of photovoltaic cells? How do solar panels work? The following cluster of words will give you all the answers. Keep reading!
Photovoltaic Cells: What are They Made of?
Photovoltaic cells are made up of layered materials that are inclusive of two types of silicon; crystalline or amorphous. It is essential to modify silicon with other materials in order to make a long-lasting photovoltaic cell. Hence, for this reason, elements such as phosphorus and boron are fused with silicon. Interestingly, silicon, when modified with phosphorus, is a good combination for the fact that phosphorus is in possession of one electron in its outermost shell, that can easily be tossed off by the sunlight energy.
Photovoltaic cells are inclusive of one or more electric fields which create a certain kind of path for the tossed-off electrons in the form of a current. It is because of this current that charging certain gadgets or electronic devices is easier, as this current can be brought into external use. Many buildings have photovoltaic shingles, which not only save them large amounts of energy, but also enhance the look of their buildings.
Photovoltaic Cells: Different types
Today, with technology surmounting everyday, numerous ways have been introduced to gain maximum efficacy at minimal cost. One such way is the usage of concentrated photovoltaic cells. Strikingly, this system of soaking up the solar energy is one of the most common methods. In large plants, these solar power systems bring into use giant mirrors and lenses to focus on an, undoubtedly, wide spectrum of sunlight into a small area. When more sunlight is absorbed, more electricity is produced.
These days, photovoltaic cells and solar panels for electricity generation are produced in two forms, viz., organic and inorganic. While inorganic PV cells are costly because of the materials used to make them, organic photovoltaic cells are highly cost-efficient due to a number of reasons. Organic PV cells make use of a graphene substrate that is printed on a thermo plastic, thus making it highly cost-effective, light-weight, and portable.
Many companies dedicated to science and technology have put up a wide variety of photovoltaic cells for sale, both for personal use and professional usage. The cost of photovoltaic cells is highly dependent on the infrastructure used to make them. A basic photovoltaic arrangement comprising a 50-watt solar panel costs approximately $700 - $800. It is portable, and has a rather high efficiency. On the other hand, a photovoltaic solar panel system that is created to produce up to 600 watts of energy may go up to $8000 - $10000. However, with new products, technologies, and implementations being introduced in the market everyday, the prices of photovoltaic cells tend to decrease with a much lesser harm to the environment.
Photovoltaic cells are no less than a boon to the global society. They require no fuel, and no worrisome functionalities. Instead, they soak up one of the most abundant resources available on earth; sunlight. This has made solar cells one of the most sought-after resource saving systems across the globe, thereby, keeping the environment safe and sound.
