The spectral response and the quantum efficiency are both used in solar cell analysis and the choice depends on the application. The spectral response uses the power of the light at each wavelength whereas the quantum efficiency uses the photon flux. Converting QE to SR is done with the following formula:
The spectral response is conceptually similar to the quantum efficiency. The quantum efficiency gives the number of electrons output by the solar cell compared to the number of photons incident on the device, while the spectral response is the ratio of the current generated by the solar cell to the power incident on the solar cell.
Other than spectral response, there are many other factors, i.e., weathering, mishandling, aging, etc., that could contribute to the inefficiency of solar cells and this can be projected clearly by obtaining a solar cell’s quantum efficiency as well as its spectral response.
To map the performance expected under the varying spectra found in operating conditions, solar cell efficiencies have been evaluated using solar spectra generated by the National Solar Radiation Database, applied to confirmed record-efficiency cell parameters.
Filter efficiency was 62% for a thin-film solar cell (GaAs) and 56% for a crystalline silicon solar cell (c-Si). Installation of filter fluid, which was placed directly in front of the PV receiver, re-collected the light that went through the filter and reflected it off the PV cell. A schematic diagram of the system is shown in Fig. 18.23.
Generally, I–V curves are given preference when measuring the performance of solar cells and less emphasis is given to spectral response, internal quantum efficiency (IQE), and external quantum efficiency (EQE) quantum.
