In order to understand how contacts influence the performance of solar cells, we previously developed and presented the concept of partial specific resistances: for each contact of a solar cell, we defined voltage-dependent specific resistances to electrons and to holes. Although the connection between these partial specific resistances and the cell performance metrics at open circuit (iVoc and Voc) is straightforward, the relationship becomes more complex when current flows out of the cell, in particular at the maximum power point. In the present work, we investigate the dependence of these hole and electron specific resistances on implied voltage. We show that the shapes of these curves - and not simply the resistance values at the maximum power point, which do not correspond to the same injection level in every cell - dictate the cell efficiency.
