If the silicon and the phosphorus are combined chemically, the result is eight electrons with an additional free electron for the stroll. In order that the electricity flows, also a positive charge is due to create. This is obtained in the solar paddles by means of silicon combination with an element like the boron, that only has three electrons to offer. One of silicon by a boron plate continues having the place left by another electron. This means that the plate has a positive charge.

The two plates are put in the solar paddles, with the conductive wires that run among them. With the two plates in his place, it is hour to bring solar light in the solar paddles. The solar light emits many different particles of energy, but those that interest to us they are those calls photon. A photon acts essentially like a hammer in movement. When the plates of negative solar cells are indicated in an angle adapted for the sun, the photons bomb silicon and atoms of phosphorus.

Finally, the ninth electron, that anyway wants to be free, falls in the outer ring. This electron does not remain free for a long time, since the silicon is entered in its own outer band. As photons of the sun more electrons are come off, these generate the electricity. The electricity generated by a cell to pave is not very impressive, but when all the conductive wires draw free electrons of distance of the plates, there is no sufficient electricity to feed motors on low amperage and other electronic devices. What the electrons do not use or is lost in the air is given back to the negative plate and all the process begins again. One of the main problems with the use of solar paddles is the small amount of electricity whom they generate in comparison with his size. A calculator only can demand a single solar cell, but a car solar-powered would require thousands. If the angle of the solar paddles changes although it is slightly, the efficiency can fall a 50%. Some of the solar paddles can be stored in chemical batteries, but there is not much power generally. The same solar light that also provides photons ultraviolet provides destructive infrared waveses, that they possibly cause that the solar paddles physically degrade themselves. A homemade solar paddle must be exposed to destructive meteorological elements, that also they can affect seriously its efficiency. Many sources that also talk about the solar paddles, speak of the photovoltaic cells, which make reference to the importance of the light in the generation of electrical tension. The challenge for the scientists of the future will be the creation of sufficiently small more efficient solar paddles for practical and sufficiently powerful applications like creating the excess of necessary energy for when the light of the sun he is not available.
