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:
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.
The cells were tested under actual operating conditions and were subject to environmental variations at the site where they were installed. There was a difference in the spectral response of the photovoltaic modules in the red, green, and blue bands, with relative efficiencies of 23.83%, 19.15%, and 21.58%, respectively.
The influence of the spectrum is obtained through the use of spectrometers and sophisticated mathematical methods (i.e., by indirect methods). In this work, photovoltaic cells are exposed to just a specific wavelength range of the solar spectrum at a time through the use of color filters.
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.
