Answer:
Explanation
The Axon or nerve fibre is a long, thin projection of the neuron or nerve cells that sends signals in the form of electrical impulses from the cell body (soma) to the synaptic terminals. The axons are of two types: myelinated and unmyelinated. The unmyelinated axons lack myelin sheaths which make the transmission of electrical impulses slower while the myelinated axons transmit electrical impulses faster.

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.
