The reciprocal slopes of a current–voltage curve at open‐circuit‐ and short‐circuit‐conditions are frequently mentioned as apparent series ( R s ) and shunt ( R p ) resistances in emerging solar cell materials research. The relationship between such values and those in the one‐diode equivalent‐circuit model is studied by using exact analytical expressions of the current–voltage slope. It is found that the apparent R s and R p significantly deviate from true R s and R p .
