Photovoltaic panel response spectrum
The spectral response (SR) of a PV device is the fraction of available irradiance that is converted into current. When a device is tested in a lab or outdoors, the spectrum of the light source may not be the same as that of the reference spectrum. Different materials and their band gaps affect the spectral response, making silicon a popular choice for solar cell. . Abstract — We present a measurement system for absolute differential spectral responsivity of solar cells based on high-powered LED arrays coupled to an optical light guide capable of large area illumination. It is a fundamental concept in understanding how well a solar cell utilizes the sun's energy. An overview of typical measurement facilities for the characterization of PV modules' spectral responsivity is presented.
