Influence of electrical and optical losses on fundamental solar-cell parameters

We present here an analysis of the dependence of the light-generated current on the current at maximum power in lossy solar cells. that is, cells with both series and shunt resistances present simultaneously - that is, a real cell. It is essentially seen that this dependence is highly sensitive to series resistance. However, for cells with series resistance of the order of 3 Ω, π{variant}I _g/π{variant}I _mp=1. We also look at the influence of TiO_x antireflection coatings on the open-circuit voltage and short-circuit current in silicon solar cells.
