Solar cell is the basic building module and it is in octagonal shape and in bluish black colour. Each cell produces 0.5 voltage. 36 to 60 solar cells in 9 to 10 rows of solar cells are joined together to form a solar panel. For commercial use upto 72 cells are connected. By increasing the number of cells the wattage and voltage can be increased.
Construction of Solar Cell. A solar cell is a p-n junction diode, but its construction is slightly different from the normal junction diodes.
