HOW SOLAR CELL IS MADE?

The main component for making of solar cell is silica (that is sand). It is heated to 1500⁰C and this forms as a gel. Then this 1500⁰C gel is brought to 0⁰C immediately, so then it becomes hard.  Then we can get glass like material and that to  transparency. By going in to brief  silica is converted to metallurgical grade silicon by coke reduction and then it is dissolved in HCL and then it is send to distillation in which any salts are present that may be removed. Then we get high purity trichlorosilicane. Then it is of poly crystalline silica and it is heated to 1500⁰C we get silicon crystal and these are solids and are made in to pieces by using diamonds and we get silicon pieces. So that’s how solar cell’s are made. There are 36 cells per panel generating of 270 W nearly.
