You''re likely most familiar with PV, which is utilized in solar panels. When the sun shines onto a solar panel, energy from the sunlight is absorbed by the PV cells in the panel. This energy creates electrical charges that move in response to an internal electrical field in the cell, causing electricity to flow.
Once the PV cells have been assembled into a solar panel, the overall efficiency ends up lower than the efficiency of the cells from which it is made:. The glass coversheet and plastic encapsulation introduce reflection and absorbtion losses in the light incident upon the cell; Practical manufacturing tolerances mean that cells are laid out with small gaps between them - …

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.
Best solar panels for efficiency. Another important solar panel feature is efficiency rating, or how much sunlight a panel converts into electricity.. The most efficient solar cell of any kind has an efficiency of 39.5%, but is designed for space applications, not an ordinary roof.. Residential solar panels typically range between 15% and 20%, with the industry-leading panels pushing 23%.
