What is photovoltaic (PV) technology and how does it work? PV materials and devices convert sunlight into electrical energy. A single PV device is known as a cell. An individual PV cell is usually small, typically producing about 1 or 2 watts of power. These cells are made of different semiconductor materials and are often less than the thickness of four human hairs.

PV has made rapid progress in the past 20 years, yielding better efficiency, improved durability, and lower costs. But before we explain how solar cells work, know that solar cells that are strung together make a module, and when modules are connected, they make a solar system, or installation. A typical residential rooftop solar system has
Photovoltaics (often shortened as PV) gets its name from the process of converting light (photons) to electricity (voltage), which is called the photovoltaic effect.This phenomenon was first exploited in 1954 by scientists at Bell Laboratories who created a working solar cell made from silicon that generated an electric current when exposed to sunlight.
