A photovoltaic (PV) cell, commonly called a solar cell, is a nonmechanical device that converts sunlight directly into electricity. Some PV cells can convert artificial light into electricity. Sunlight is composed of photons, or particles of solar energy.
The main types of photovoltaic cells include: Silicon photovoltaic cell, also referred to as a solar cell, is a device that transforms sunlight into electrical energy. It is made of semiconductor materials, mostly silicon, which in turn releases electrons to create an electric current when photons from sunshine are absorbed.
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.
As sunlight is absorbed by the silicon, the energy from the sunlight knocks some of the electrons loose. The electrons then flow through the metals that are attached to the silicon. This flow produces the electrical current that provides power.
The characteristics of Photovoltaic (PV) cells can be understood in the terms of following terminologies: Efficiency: Determines the ability to convert sunlight into electricity, typically measured as a percentage. Open-Circuit Voltage (Voc): Maximum voltage produced when not connected to any external load.
Working principle of Photovoltaic Cell is similar to that of a diode. In PV cell, when light whose energy (hv) is greater than the band gap of the semiconductor used, the light get trapped and used to produce current.
