The cells inside the photovoltaic panel

In this article, we'll look at photovoltaic (PV) solar cells, or solar cells, which are electronic devices that generate electricity when exposed to photons or particles of light. This conversion is called the photovoltaic effect. We'll explain the science of silicon solar cells, which comprise most solar panels.

Simply put, photovoltaic cells allow solar panels to convert sunlight into electricity. You've probably seen solar panels on rooftops all around your neighborhood, but do you know how they work to generate electricity?

There are many photovoltaic cells within a single solar module, and the current created by all of the cells together adds up to enough electricity to help power your home. A standard panel used in a rooftop residential array will have 60 cells linked together.

You've likely seen photovoltaic cells in action, whether it's solar panels on rooftops, large solar farms stretching across fields, or even smaller panels on calculators, traffic signals and street lights. These cells are the heart of every solar energy system.

Commercial solar installations often use larger panels with 72 or more photovoltaic cells. A solar cell works in three generalized steps: The photovoltaic effect is a complicated process, but these three steps are the basic way that energy from the sun is converted into usable electricity by solar cells in solar panels.

A solar cell (also known as a photovoltaic cell or PV cell) is defined as an electrical device that converts light energy into electrical energy through the photovoltaic effect. A solar cell is basically a p-n junction diode.
