Comparing the results for each solar cell under the different
illumination sources shows that the output power
density of the MC-SP0.8
falls significantly when the illumination is changed from incandescent to CFL (95% reduction)
and white light LED (96% reduction). This indicates
that the key wavelengths from which the MC-SP0.8 converts the most energy lie outside of the range of emission of the CFL and LED sources.
