The series resistance is a lumped parameter value which represents the summation of several loss mechanisms in a solar cell. For example, losses due to resistance introduced in cell solder bonds, emitter and base regions, cell metallisation, and cell-interconnect busbars all contribute to the value of R s (Green, 1998).
