This increases the quantum efficiency of the cell.
The calculation is based on the intensity of light measured and the quantum efficiency of each detector.
Film morphology can also have a drastic effect on the quantum efficiency of the device.
The counting efficiency is determined by the quantum efficiency and any electronic losses that are present in the system.
However, it is often useful to look at the quantum efficiency of the light left after the reflected and transmitted light has been lost.
Current organic photovoltaics have shown 70% of quantum efficiency for blue photons.
This shows for an optimum value of quantum efficiency the bandwidth has to sacrifice.
Two types of quantum efficiency of a solar cell are often considered:
The external quantum efficiency therefore depends on both the absorption of light and the collection of charges.
They exhibited a peak quantum efficiency of 0.4% at 800 nm.
