How PV Cells Work
A typical silicon PV cell is composed of a thin wafer consisting of an ultra-thin layer of phosphorus-doped (N-type) silicon on top of a thicker layer of boron-doped (P-type) silicon. An electrical field is created
In this article, we'll look at photovoltaic (PV) solar cells, or solar cells, which are electronic devices that generate electricity when exposed to photons or particles of light. This conversion is called the photovoltaic effect. We'll explain the science of silicon solar cells, which comprise most solar panels.
The photovoltaic effect starts with sunlight striking a photovoltaic cell. Solar cells are made of a semiconductor material, usually silicon, that is treated to allow it to interact with the photons that make up sunlight.
Solar PV cells are primarily manufactured from silicon, one of the most abundant materials on Earth. Silicon is found in sand and quartz. To make solar cells, high purity silicon is needed. The silicon is refined through multiple steps to reach 99.9999% purity. This hyper-purified silicon is known as solar grade silicon.
Silicon solar cells are classified according to the type of the silicon material used for solar cells. Those include the highest quality single crystalline, multicrystalline, polycrystalline or amorphous.
