Introduction

Analysis and Working of Solar Cell

First of all, talking about what the cell looks like from the fact that it is a kind of bluish black. Picture in your mind a sandwich with two pieces of  Bologna in it. There Mayo on top of bread. This is the anti-reflection film to keep the electrons to escape. But other than that, there are just two slices of bread with two pieces of Bologna in the middle. Remember when you were young and would squish bread in your hands until it was a flat square?  Well, a solar cell is about this size, it will fit in the palm of the hand.  Now, instead of bread, two pieces of the image of metal, with two pieces of  Bologna in the middle. The metal is called a "driver" because electricity  will flow easily through it. The Bologna process, or silicon, is  called a semiconductor because it will not normally conduct electricity unless  it is required to do so. The top layer of silicon is processed, or "doped"  so it has too many electrons in it, this is called an "n-type"  layer with "N" standing for negative (positively charged). The bottom layer  Silicon is processed, or "doped" so that it has too few electrons (negative charge) and is called the "type p" Positive or layer.  A copper wire coming out of the bottom metal plate and a copper wire is out the upper metal plate. See all this son run a lamp or bulb, or dishwasher, something that runs on electricity. So the wire coming out of the upper metal plate is negative "-" and the short wire to the bottom plate is positive "+". So now you know how it looks, but what does it do?  Solar cells are also called photovoltaic cells. "Photo" means light, and "voltaic" means electricity. Literally, the power of light. Many people who have had solar calculators that lacked jus learned that they could shining any light on the calculator and it would give him the power to work. The reason we use the term "solar" is because the cells for a wide range (group) of cells work you need a lot of light and the sun (Solar) can provide light. (Perlin, 2004,Pp 87)

The electrons in the cell are attached to atoms and when the light strikes the cell, it causes the atom to generate an "electron-hole". The "electron" is in the n-type layer and the "hole" is in the p-type layer Electrons move from the upper layer bottom and passes through the copper wire, producing enough voltage (power supply) to produce electricity. (Mark , 2009, p. 4) The holes move in a counterclockwise direction and the current is always opposite to the flow of electrons. Thus, the energy moves in a circle, the metal plate at the bottom, through the wire, the lamp, the lamp through the wire top, the top plate and back in the top layer of ...
