What is the spectral efficiency of photovoltaic panels

Spectral efficiency measures how well a solar panel converts different wavelengths of sunlight into electricity. Optimizing spectral response involves selecting materials and designs that match the regional solar spectrum. Narrow or wide bandgap materials influence which wavelengths are captured. . The conversion efficiency of a photovoltaic (PV) cell, or solar cell, is the percentage of the solar energy shining on a PV device that is converted into usable electricity. It is an essential factor in understanding the overall performance of solar cells and, consequently, solar panels. 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.
