Conceptual error in the calculation of the AM1 short circuit current from light biased spectral quantum efficiency measurements

The authors point out a conceptual error in the calculation of the AM1 short circuit current of solar cells whose current response is not a linear function of photon flux where the generally accepted procedure is to use AM1 light biased quantum efficiency data. Such an error can be minimized if the cell is placed under a d.c. light bias of 0.37 AM1 irradiance. Finally, data showing departures from linearity on a crystalline Si cell and on several a-Si cells is presented.
