Solar Photovoltaic Technology Basics 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
- Photovoltaics and electricity - U. S. Energy Information Administration . . .
A PV cell is made of semiconductor material When photons strike a PV cell, they will reflect off the cell, pass through the cell, or be absorbed by the semiconductor material Only the photons that are absorbed provide energy to generate electricity
- Solar Photovoltaic Technology Basics | NREL
Photovoltaics (often shortened as PV) gets its name from the process of converting light (photons) to electricity (voltage), which is called the photovoltaic effect
- Photovoltaic system - Wikipedia
A photovoltaic system, also called a PV system or solar power system, is an electric power system designed to supply usable solar power by means of photovoltaics
- Solar PV Energy Factsheet - Center for Sustainable Systems
PV conversion efficiency measures the percentage of solar energy converted to electricity 7 While most available solar panels achieve ~20% efficiency, 8 researchers have developed modules approaching 50% 2 The highest lab efficiencies are 40 6% for hybrid four-junction cells and 35 9-38 9% for gallium arsenide (GaAs) III-V concentrating
