In the context of solar cells, series resistance (Rs) and shunt resistance (Rsh) are important parameters. These values are typically unpublished by solar cell and module manufacturers and must be obtained independently. The series resistance is a lumped parameter value which represents the summation of several loss mechanisms in a solar cell.
The series resistance (Rs) in a solar cell is a lumped parameter value that represents the sum of several loss mechanisms in the solar cell. These losses can come from resistance introduced in cell solder bonds, emitter and base regions, cell metallisation, and cell-interconnect busbars (Green, 1998 ).
