Concentrator photovoltaics (CPV) or also called “concentration photovoltaics” is a type of photovoltaic (PV) technology that generates electricity coming from solar energy.. For generating electricity CPV uses lenses or curved mirrors to focus sunlight onto small, high-quality multi-junction (MJ), and highly efficient solar cells.

The operating temperature of the PV solar cell is quantified by an energy balance. Solar cells absorb solar energy, which is partly converted into electrical energy and partly into thermal energy, causing a rise in the operating temperature of the cell. The electrical energy gained from the cell can be exploited in the external circuit. Eq.
The solar field is made up of an array of mirrors or reflectors that gather and concentrate solar energy onto a receiving tube. The receiver tube absorbs heat from the focused solar radiation using a thermal energy carrier called Heat Transfer Fluid (HTF), which may then be utilized directly or in conjunction with a secondary circuit to produce electricity .
