PV cells, or solar cells, generate electricity by absorbing sunlight and using the light energy to create an electrical current. The process of how PV cells work can be broken down into three basic steps: first, a PV cell absorbs light and knocks electrons loose. Then, an electric current is created by the loose-flowing electrons.
The efficiency that PV cells convert sunlight to electricity varies by the type of semiconductor material and PV cell technology. The efficiency of commercially available PV panels averaged less than 10% in the mid-1980s, increased to around 15% by 2015, and is now approaching 25% for state-of-the art modules.
In order to create the flow of electrons within the solar cell, the electrons must be excited out of their stable ‘ground’ state up into the higher energy level needed for them to move from the p-type to the n-type side. This amount of energy is equivalent to the difference in electronegativity between the two layers (this is called the band gap).
The process of conversion involves several steps. Starting with the absorption of sunlight by photovoltaic cells within the solar panel. These cells contain semiconductors that convert sunlight into DC electricity. The DC then flows through wiring to an inverter where it’s converted into AC electricity.
Once the electricity, generated by the solar PV cells, it’s sent to an inverter. Where it’s converted from direct current (DC) to alternating current (AC). Which is suitable for use in households and businesses. Solar energy conversion offers a clean, sustainable way to generate electricity.
Each solar cell has two sets of metal gridlines connected to its surface, called fingers and busbars. The electricity is collected in the fingers, which are the very thin set of metal gridlines that run up and down the solar cell. The fingers route the electricity to the busbars, which run perpendicular to the fingers.
