solar cellThe reciprocal slopes of a current–voltage curve at open-circuit- and shortcircuit-conditions are frequently mentioned as apparent series (R_s) and shunt(R_p) resistances in emerging solar cell materials research. The relationshipbetween such values and those in the one-diode equivalent...
