On quantum efficiency of nonideal solar cells

A simple approach for the calculation of the width of the space charge region (and consequently the concentration of uncompensated acceptors), which takes into account the effect of the series resistance on the quantum efficiency of anisotype asymmetrical thin film heterojunction solar cells (on the example of CdS/CdTe solar cells), was proposed. The effect of the light dependent series resistance and current transport mechanism was also taken into consideration.

► The light dependent I–V characteristic of CdS/CdTe solar cells was analyzed.
► A simple approach for the calculation of W and NA − ND was proposed.
► The effect of the light dependent Rs, n and I0 on the photoelectric quantum yield was taken into consideration.
