Solar PV

Everything You Need to Know about Solar PV Technology

Solar PV by definition

Solar PV (or solar photovoltaic) system refers to the renewable energy technology, which converts solar radiation (sunlight) into direct current electricity with the use of semiconductors. When sun rays hit the semiconductor of the solar PV cell, electron charges are then released, causing it to produce electric current.

Semiconductor

A semiconductor is a material that has an electrical conductivity level around the middle of the scale of a metal and an insulator – depending on the temperature and presence of impurities, its conductivity will vary. One of its many characteristics is that, as its temperature rises and the amount of applied impurity increases, its ability to conduct electricity also increases. 

Examples of semiconductor substances include silicon, germanium, antimony, arsenic, boron, carbon, selenium, gallium arsenide, sulfur, and tellurium.

However, the most commonly used semiconductors in manufacturing solar cells are silicon and gallium arsenide.

PV or Photovoltaic Effect

The process that takes place during the conversion of sunlight into electricity within the solar PV cell is called the photovoltaic effect. This is a combination of physical and chemical phenomenon which happens when the semiconductors, which are in the solar PV cells, are exposed to sunlight. Due to the photovoltaic effect, current and voltage is produced.
