1. PV cells  A solar cell, or photovoltaic cell, is an electrical device that converts the energy of light directly into electricity by the photovoltaic effect, which is a physical and chemical phenomenon.  It is a form of photoelectric cell, defined as a device whose electrical characteristics, such as current, voltage, or resistance, vary when exposed to light. 

1. PV cells  Individual solar cell devices are often the electrical building blocks of photovoltaic modules, known colloquially as solar panels.  The common single junction silicon solar cell can produce a maximum open-circuit voltage of approximately 0.5 to 0.6 volts.

Solar photovoltaic (PV) is the generation of electricity from the sun's energy, using PV cells.

A Solar Cell is a sandwich of two different layers of silicon that have been specially treated so they will let electricity flow through them in a specific way.

A Solar Panel is made up of many solar cells.

A Solar array is a collection of multiple solar panels that generate electricity as a system.

What is battery technology?

A battery is a combination of two or more electrochemical cells.

These electrochemical cells store energy in the form of chemical energy, and this is converted into electrical energy when connected to an electrical circuit in which an electrical current can flow.
