Although solar electricity producing devices have been around for over 50 years, solar electricity devices, often referred to as photovoltaics or PV, are still considered cutting edge technology. The promise of clean, cheap, and abundant electricity from the sun has been the dream of many scientists and businesses. As a result each year a number of discoveries and advances for this technology have been made.
This primer has been designed to cover some of the basic concepts, components, and uses of PV. Explore each of the sections below to begin your enlightening journey.
Current PV Technology
Since the earliest PV cell created at Bell Labs, the technology has come a long way. Read this section to get a look at what types of PV technology are available today.
History of PV
Since its recognized beginning at Bell Labs over 50 years ago, each year has brought a number of important discoveries to this technology. Explore this section to review the history of this important technology.
How PV Cells Work
Though they have "no moving parts" PV cells are very complex devices. Here we look at how light from the sun is used to generate electricity.
Cells, Modules, & Array
At the heart of any PV system is the PV cell. From there, cells are connected together into modules and those modules are connected into arrays. This section explores how the various components described are connected together.
How a PV System Works
In order to power large systems using PV like buildings, PV panels are connected to other electricity management and storage devices such as batteries. We'll explore what the roles of these components are.
Types of PV Systems
There are a variety of ways that PV systems can be designed. This section explores some of the more common configurations of PV systems.
