Learning that the solar panel for home, a person can use in a DIY situation, pay attention to the parts of the solar cell is essential.
A photovoltaic cell, also called a solar cell, is the main component that generates electricity in a solar panel. Photovoltaics is a term that refers to the production of electricity at the junction of two semiconductor silicon is exposed to light (not necessarily sunlight) and comes from the word “photo” means light and electricity, meaning “voltaic “. When grouped together, they form a module which can then be inserted into a frame to a solar panel. Solar cells are found in some computers, satellites, and even in the Mars rovers are also called solar cells or panels. Any light that hits a solar cell can cause a reaction in the creation of electricity. The light source would be the most effective sun.
Parts of a solar cell are:
1. P-type Semiconductor
– This is a very thin layer comparable to the thickness of a paper or a card that is designed to have a false and move the positive particles called “holes”. Imagine this layer positive particles that want to bond with people who are negative and keep moving until they find an inverse correspondence takes.
2. n-type semiconductor
– This is essentially the same as the p-type layer, except that carries “electrons” free movement. Imagine a being that carries negative particles that are also always looking for positive partner face. This is also the part of the cell where the light passes through.
3. PN junction
– This is the part of the solar cell that is created when the P-type semiconductor and N-type are connected. This is where the electric field is created and separated “holes” (positive) “e” (negative). This splitter or union is then affected when hit by light causing the particles to move passion on either side of the partition.
4. Positive Lead
– This is the layer at the bottom of the P-type semiconductor and functions as a way for the particles to pass from P to N, or vice versa. This is where the positive cable is connected.
5. negative lead
– This also serves as a route for the same particles as the positive conductor layer. This part of the solar cell is generally represented by the bands above the N-type semiconductor, in which the light is emitted. This is where you connect the negative cable.
6. antireflective coating
– Silicon may reflect an estimated 35% of sunlight and hence a layer that can prevent this must be put in place. This is the task of the anti-reflection layer where sunlight is issued, effectively providing a better basis for semiconductors.
How do they work these parts is very simple (but can be complicated in detail); P type containing the positive particles while maintaining the N-type negative effects; They are then moved when the light hits the PN junction; the movement is then extended to channels that are the positive and negative conductors that create the electrical current when intercepted can be used to power electrical devices.
The solar cell can be combined to make a chain which can also be combined with similar channels creating a module that, when mounted in a frame, makes a solar panel, which, in turn, can be connected to other solar panels creating a solar panel. Provided the cells are combined, the output power increases, thus providing a plurality of devices, or even an entire city. You are now on track to build the right solar panel for the house.
