A solar cell is a device which produces electricity from light through photovoltaic effect. This solar cell is the term especially used in the case of capturing light from sunlight and the term photovoltaic cell is mostly used when you capture light from any other device. Both involve converting the light energy into electricity. These solar cells can be converted into solar panels, solar modules or photovoltaic arrays by the assembly of solar cells. This produces an energy which is called as solar energy.
Even though the idea of solar energy production from light was from earlier days, the modern age of solar power technology started in 1954. From that time onwards many advances were made and many types of solar cells have been introduced. Solar cells are hitting the market frequently with various modifications and advancement in technologies. There are many different solar cells for sale.
You can find solar cells for sales in many places both online and offline. The costs of these solar cells are established according to cost-per-watt. In the case of infrared capable photovoltaic cells cost depends on the cost-per-watt in 24 hours. As the cost is too high it is not within the price range of many people. Hence, university of Utah engineers planned to design a new way solar cell with thin wafers of the chemical element germanium; this reduces the cost by a massive amount.
The use of solar cells in your house will reduce your electricity bill by a huge amount of money. As the use of this kind of cell increases, the production of any kind of renewable energy can be pumped back into the grid earning you some extra money. An average household requires a power system that produces 3 to 5 KW but if used properly then 1 KW unit is enough for all lights, running of TV, DVD, microwave and other ordinary household things.
When looking for solar cells for sale for your household it will probably work out to be around $5 per watt. So any household requirements needs an investment of $ 15,000 to $25,000 whereas the PV i.e., photovoltaic panel this will cost around $9,000 to $15,000.
Cheap solar cells are everyone’s goal. Right now the cost of installing enough solar panels and batteries in your house to power all of your electronic devices is in the neighborhood of $32,000. Of course, the solar cells themselves will last approximately twenty years and even the batteries should have a life of about five years, but even so, this is a high enough cost that most people would have to take out a loan to pay off the cost of installing solar energy in their house. If your current electricity bills are $100 per month, it will still take twenty six years before your solar energy system has paid for itself. Therefore, the hunt for cheap solar cells is still in progress.
Currently the country who has figured out how to manufacture the cheapest solar cells is China. This is in part because there is a ready supply of cheap and skilled labor, especially in China’s southern and eastern provinces. But it is also because China is willing to try new practices to see if they will work before many Western companies are willing to take the chance. For instance, Suntech is currently manufacturing cheap solar cells that have a sixteen to seventeen percent conversion rate, but for a much cheaper cost than the same cells in the EU or the United States.
Cheap labor and innovative business models aren’t the be all end all for cheap solar cells. New technology must also be used to make cheap solar cells. The news is currently full of potential breakthroughs in solar cell technology. For instance, a British student has pioneered a theory that artificially manufacturing melanin, a chemical found in human hair and skin that absorbs the sun’s rays, and spraying it on solar panels could increase their efficiency rate and therefore lower their cost. Other dye ideas are still in the works.
Currently, the cheapest solar cells are thin film cells, made from light and flexible pieces of silicon. However, they are not too efficient and so you need acres of them to create enough power for city. Whether the material (silicon) these cells is made more efficient or whether an entirely new process for harnessing the sun’s power comes about is hard to tell. Currently one the only ways to make solar power competitive with utility generated power is through government subsidies. However, if the economy of scale could kick in we might just yet have cheap solar cells.
Thinking about a homemade solar cell? As long as the earth has been around there has been sunlight beaming down on our planet. Thanks to technology the sun is no becoming a more popular source of power.
Fossil fuels are quickly being eating away and there is a finite amount that is available to be used. This is where solar energy is starting to come to the fore. The biggest reason to use this energy is that the power that it provides is more than enough to meet the energy requirements of every one on earth. The supply is unlimited and the energy generation itself is very clean. There are no emissions being cast into the atmosphere with a solar energy source. This is a big plus for “greenies” and those who are interested in saving our planet.
Now, if you want to make your own homemade solar cell so you can start to help save the planet then follow these instructions below.
1.
Silicon is a vital factor so let’s start with that.
You extract silicon from silicon dioxide.
You need to firstly remove any impurities and to do this you simply heat it in the oven at a very high temperature.
You need to keep repeating this process until you finish up with at least 99.5% pure silicon.
This is the very least you need to begin making your homemade solar cell.
2.
Our next step is to crystallize the solution.
To achieve crystallization you heat up the silicon until it melts then once it does you add boron.
The addition of boron creates and electrical foundation.
This then gets charged with a positive charge.
3.
You should now have you silicon in the shape of metal blocks.
Next step is to cut them into thin sheets.
For the homemade solar cells these need to be in the range of 200-300 micrometers
4.
The sheets of silicon are now dipped in water with chemical additives so that they can collect a negative charge.
Anti-reflection material is now added.
This gives the homemade solar cells black appearance; this is to help get the most from the sun’s rays.
5.
Lastly, connections are bonded to the photovoltaic cell (either silver or aluminum) to carry the electric current to your batteries or household.
Voila, you have no created your own homemade solar cell.
If you are looking for solar power information then you have come to the right place. As we all know electricity prices are getting more expensive by the day and they don’t look like they will be coming down anytime soon. This is simply for a couple of reasons. One is our ever increasing demand for energy and two is the dwindling resources we have to create this energy.
There are a number of things that you can do to help alleviate that situation I plan to do just that.
Renewal energy is all the go now and it is becoming very popular amongst the young and old. Solar power is once such source of renewable energy. In today’s world where there are limited energy supplies, we need to find and use those alternate sources if we are to survive into the future. You should really think about how you can reduce your own household energy usage. With the right solar power information your can start to produce your own free renewable energy without too much hassle or cost.
You probably are already aware that solar power works by taking the energy from the sun and converting it to electricity that anyone can use. This is accomplished by using solar cells or photovoltaic. You generally need more than a single solar cell to harness enough energy. Generally the more solar cells you have exposed to the sun, the more energy that you can generate. These solar cells are usually placed on a roof or up high so that they receive maximum exposure to the sun.
This energy that is harness will be converted into electric current which is then stored in deep recycle batteries. Your solar array (amount of solar panels) size will depend on the needs of your household and how much energy you would use. Although this is very general solar cell information it is very important if you really are considering using an alternate source of energy.
While the whole solar cell scenario can sound complicated, this isn’t necessarily the case. You can find many online plans so you can do it yourself or you can opt for a professional who will do it for you.
The goal of having a solar cell array is to save you money and to help save the environment at the same time. There are many online courses that show you how you can make your own solar power array for less than $300.If you have good DIY skills then it is entirely possible that you can do it all yourself, thus saving you even more money.
