We suggest that the measurement of electroabsorption be improved by observations of electrotransmittance and electroreflectance for amorphous silicon-based solar cells. The measurement is based on a model in which electroabsorption depends on the internal reflection and transmission and reflection are ultimately entangled to each other. Thus the model indicates that the electroabsorption is completely obtained at the condition, so called “the zero interference effect,” in which the interference effect is nulled. The condition of the zero interference effect is directly observed with a simultaneous measurement of electrotransmittance and electroreflectance, and determines the built-in potential for a transparent back-surfaced solar cell, but it is inconclusive, because of the absence of electrotransmittance, for a reflecting back-surfaced solar cell. But the built-in potential for the solar cell would rather be estimated with the offset potential at the photon energy near the absorber layer band gap (i.e., the low energy limit). © 2004 American Institute of Physics.
