Concentrator photovoltaics (CPV)

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.

Concentrated Photovoltaics

Unlike the flat-plate photovoltaic systems seen on roofs, solar concen trators must track the sun to focus light on to a solar cell throughout the day. Sun tracking increases the daily energy production above that of non-tracking flat-plate PV panels. However, electrical output drops dramatically if the sun is not focu sed on the cell, or if clouds block the sun. A concentrator
