Components of a PV module:
(1) Aluminum frame (2) Glass (3) Encapsulant (hold cells together) (4) Cells (5) Encapsulant (hold cells together) (6) Plastic backsheet (7) Module frame (8) Junction box with wires/connectors

A circuit attached to a PV cell. Electrons are energized by the sun (via photons). There is a one-way barrier the cell (depicted in red) that only allows the electrons to move in one direction. As they begin to concentrate on Side 1 of the cell are forced through the circuit.

Solar photovoltaic (PV) modules use the photovoltaic (PV) effect to generate electrical current upon exposure to light. When sufficient light hits a PV cell, current is generated which excites electrons that then pass through a one-way barrier or junction forcing them to flow through a circuit to return to their point of origin. These movement of these electrons can be used to do work or power loads. There are many different technologies available and ways to design a system that can meet needs that range from simple lighting, to running appliances, pumping water or powering cities.
