Temperaturedependent spectral mismatch corrections
This study develops the mathematical foundation for a translation of solar cell shortcircuit current from one thermal and spectral irradiance operating condition to another without the use of illdefined and errorprone temperature coefficients typically employed in solar cell metrology. Using the partial derivative of quantum efficiency with respect to temperature, the conventional isothermal expression for spectral mismatch corrections is modified to account for changes of current due to temperature; this modification completely eliminates the need for shortcircuitcurrent temperature coefficients. An example calculation is provided to demonstrate use of the new translation.
