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. The electrons are forced from the top layer of the cell through a one-way barrier or junction (depicted in red), at which point they are forced to return 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.
