About Photovoltaic Cells
Photovoltaic cells generate a voltage when radiant energy falls on the boundary between dissimilar substances. Photovoltaic cells or solar cells are semiconductor devices that have a large-area photo cell diode that is capable of generating electric energy from sunlight. This conversion is called the photovoltaic effect. Photovoltaic cells are made from a semiconducting material, generally silicon crystal. When sunlight hits the photovoltaic panel, the light is absorbed by the silicon crystal. This absorption loosens the electrons from their atoms, causing the electrons to flow through the silicon crystal and generate electricity.
There are three basic types of photovoltaic cells: mono-crystalline cells, polycrystalline cells, and amorphous cells. A mono-crystalline cell is the most efficient, but also the most costly photovoltaic cell. A polycrystalline cell is more common and less expensive, but also less efficient. An amorphous cell is relatively inexpensive, but produces much less power. As such, the solar panels made from these photovoltaic cells must be larger to produce the same amount of energy. A UV sensitive photo cell converts UV radiation to electrical energy.
