Nowadays fossil fuels like coal, petroleum and natural gas are being used up to fulfill many human needs. As the result of that usage all of them are now becoming only available in a very limited supply. As a result we must look to solar power as an alternative source of energy. In fact, many people have begun to build their own homemade solar cells and have even started using these solar cells to produce electricity for their homes and increasingly their workplaces. Homemade solar cell systems are also ideal to use on farms where electricity from a power company is not readily available.
Solar cells generated energy is a type of renewable energy. Compared to the other type of energy it is more abundant and there is no reason for it to be run out. Solar energy also will never produce pollution to our environment. Pollution may lead to the occurrence of global warming which means that by using solar cells may help us to take care of our environment and our earth will not be in danger.
With a combination of a few or more solar cells, we will be able to produce our own solar power. There is an uncomplicated method that can be used to create the cells. In order to create a solar cell what we need to do is to obtain silicon from a type of chemical called silicon dioxide. We need to ensure the silicon that we want to use free from any impurities. By placing it in a very hot furnace and heating it up, we will be able to get 99% pure silicon where we need it to create our own homemade solar cell.
Secondly what we need to do is to make crystallization to the silicon. As a step for crystallization the 99% pure silicon that we obtain before must be reheated up until the melting point reaches then boron is mixed up together. The combination of that crystallized silicon and boron will change the silicon to the positive charges material.
The positively charged silicon can now be cut into a few sheets which is every sheet size are around 200 to 300 microns. To make the silicon sheet become negatively charged they are all dipped thoroughly into chemical water. Then a layer called a ‘layer of anti reflection’ need to be put in order to make t he cells become dark.
The final step of developing homemade solar cells is to install the conductors. Either aluminum or silver can be used to ensure the cell able to conduct electricity. As for a solar panel we need to group all the solar cells. By grouping all of them together we are now have a solar powered energy device that can be used to generate to us electrical energy.
There are so many people are now build their own homemade solar cells. This lead most of them to produce their solar generated energy. Through the usage of solar generated electrical energy, they can save their money, people also may now able to conserve the diminishing supply of fossil fuels.
