Amorphous silicon cells have a spectral response range of 400 nm to 800 nm, compared to 400 nm to 1100 nm for crystalline silicon cells. When testing amorphous silicon cells using simulators calibrated with crystalline silicon standards, the infrared-rich spectrum (800 nm to 1100 nm) contributes to the current of crystalline cells but not to amorphous cells. This results in a severe
