Energy output of solar cells: Eliminating uncertainty in photovoltaics 

Photovoltaics (PV) are devices made up of solar cells that use the properties of semiconductor materials to convert energy from the sun into electricity. When PV devices are sold, they are classified according to their energy output. Prior to this project, the energy output of PV was measured under standard test conditions (STC) specific to the USA, and of little relevance to real operating conditions in Europe. This could lead to inaccurate estimates of the energy generated when used under real operating conditions. This project developed a new classification system of PV devices based on their energy output under different climate zones that led to the new standard IEC 61853. This reliable data enables governments and industry to make informed decisions over which PV technologies are most suitable.
