One noticeable influence on the global breakdown voltage of solar cells is the general surface roughness, which is mainly determined by the texturization process. The electrical and optical coupling between subcells in a multijunction solar cell affects its external quantum efficiency (eqe) measurement.

In this study, we show how a low breakdown voltage of a component subcell impacts the eqe deter­ mination of a multijunction solar cell and demands the use of a finely adjusted external voltage bias. We have shown that these conditions can significantly affect the spectral response measurements of all three junctions, with the ge junction affected the most.

Unless this is a homework question the better way is to actually measure the breakdown voltage. This can cause the current to change over time, even when the voltage is kept constant. For solar cells made from multicrystalline (mc) silicon, electrical breakdown is found to occur at much lower reverse voltages (−13 v) than expected from theory (−60 v) [1].

Load + _ figure 1. The electrical and optical coupling between subcells in a multijunction solar cell affects its external quantum efficiency (eqe) measurement. For example, if the cell is completely shaded, then the unshaded solar cells will be forward biased by their short circuit current and the voltage will be about 0.6v.
