A solar cell is basically a junction diode, although its construction it is little bit different from conventional p-n junction diodes.A very thin layer of p-type semiconductor is grown on a relatively thicker n-type semiconductor.We then apply a few finer electrodes on the top of the p-type semiconductor layer.. These electrodes do not obstruct light to reach the thin p-type layer.

The working principle of this pump is, it pushes the underground water to the surface through changing energy from rotary to kinetic and finally into pressure energy. This process can be done through the water being dragged into the water pump first, where the revolution of the impeller drives the water using the diffuser.
