IEC 60904-8 | Measurement of spectral responsivity of a photovoltaic (PV) device (I)

The Spectral Responsivity (SR) is a significant indicator for evaluating photoelectric detectors, such as solar cells, photometers, optical detectors, etc. Each photoelectric detector has different spectral responsivity in different wavelength range.

IEC 60904-8 describes the requirements for the spectral responsivity of both linear and non-linear photovoltaic devices. The spectral responsivity of PV devices is used in cell development and cell analysis, as it provides a measure of recombination and other processes occurring inside the semiconductor or cell material system.
