The higher the number of cells getting wired together in a photo-voltaic cell, the higher its electricity or energy yield would be. In addition, the primary function of a PV panel is to convert light energy from the sun directly into electrical energy in a form of voltage that could be used by electricity-consuming devices.

When the two hydrogen atoms bond with the oxygen, they attach to the top of the molecule rather like Mickey Mouse ears. This molecular structure gives the water molecule polarity, or a lopsided electrical charge that attracts other atoms.
