In a solar cell module, do the silver lines which are used as electrodes reflect incoming light?

Although it should, but do we really take into account their area while calculating efficiency because in that particular area no light is actually absorbed.

Why is the short circuit current calculated from EQE measurement different to Jsc from I-V measurement? Could it be corrected?

 I have calculated Jsc from EQE measurement which is almost 1mA/cm2 less than normal Jsc measured from  solar cell I-V data. Could anyone help to correct it. I will be very thankful.
