photovoltaic cell (PV Cell) A photovoltaic cell (PV cell) is a specialized semiconductor diode that converts visible light into direct current (DC). Some PV cells can also convert infrared (IR) or ultraviolet (UV) radiation into DC electricity.
A photovoltaic module is a grouping of connected solar cells used to collect energy from solar radiation. Each cell is electrically connected into these modules, which in turn are merged into a panel. When photovoltaic panels are installed at various locations they become known as arrays.
