On our earth solar power is a source of primary energy and this form of energy is one which has been used forever and an example is hanging the clothes to dry outside as being one of the times that we use the energy from the sun. Food generated in plants comes from the solar light and then the animals eat the food. Solar power of all the energy sources is the cleanest and nearly all the earth's natural processes come from this source. The sunlight is collected and then it is converted into electricity so this is called solar power.
How is solar energy generated?
Explosions happen called thermonuclear when helium atoms and hydrogen atoms are fused together and then huge bursts of energy are released. Some of this results in radiation which is a free energy source for the solar panels which are homemade. Electrical energy comes when these solar panels are converting this form of radiation which then can be stored in a battery form to be used later on.
Two ways to generate power
1. Direct-Using solar or photovoltaic cells PV the sunlight will be converted into electricity directly.
2. Indirect-Boiling water is an indirect way to use the suns energy so that the steam that is made moves the turbines and then these are used for indirectly providing power in CSP concentrating solar power.
Uses of solar power
Hand held calculators electronic equipment emergency road signs buoys remote solar-powered sensors and also lights in a parking lot. Some boats and experimental vehicles are using solar powered energy now too. One of the best is the solar panels which are placed outside buildings where the solar cell is continuously charged during the daylight so that at night the electricity is then free so that the streets are lit and providing security for everyone. Satellites are using solar panels where the solar cells are providing power for the electrical systems to operate on the satellites.
Science behind the generation of solar power
Solar panels is what is used to generate solar power as they have photovoltaic cells or the common name being solar cells and when they are arranged in a pattern on a grid surface they collect the energy. Silicon is one material used in solar cells and when the solar energy falls on these solar panels the energy generated knocks loose the electrons and then they can be free to flow. The current then is an electric field and the free electrons flow in that direction. Contacts of metal have to be put in place on the bottom and top of the solar cells to draw this current for use externally. The cell made from silicon known as the single-crystal is one solar cell to consider.
Properties of different chemicals are in silicon in the form of crystalline. There are 14 electrons in one atom of silicon and they are set in shells of 3 varieties. Two shells being the inner ones are joined to the nucleus and then are full as the outer shell has 4 electrons. Then there is an outer shell which is short 4 electrons and the silicon atom will be looking for ways to fill up that last shell. To complete the outer shell the 4 electrons will be shared with the near silicon atoms and this process forms a crystalline. This explains crystalline silicon but pure crystalline silicon is such a poor conductor as all the electrons are locked in.
In order to have the solar cells conduct more there are some impurities put into the silicon in order for the solar cells to work properly so these impurities help in this process. An atom of silicon has 5 electrons in its shell which is the outer one. Phosphorous is free and there is 1 electron in phosphorous so that when the silicon atom bonds with its neighbors the phosphorous is then freed. When the heat or energy is also added to this most of these electrons will then go free too so then there are many free carriers produced. This process which takes place when you add impurities is named doping and when the doping of phosphorous into the silicon atom takes place then and only then will the silicon which we will get is then called N for negative or N-type because of the free electrons domination which takes place.
The solar cell then has this N-type but to get another part of the silicon atom it is doped with some boron and this has 3 electrons instead of 4 in the outer shell of it in order to turn it into a P-type silicon. P is for positive where the other one was negative and this P-type actually has free holes. When you put the N-type and the P-type silicons together and the free electrons from the side of N so then this requires some place for the holes to fall into so the free holes on the P-type side and then they rush in to fill up the hole. This then completes the field of electricity which in turn makes our cells of solar power work.
