What is a series resistance 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 ).
Does series resistance affect a solar cell at open-circuit voltage?
Series resistance does not affect the solar cell at open-circuit voltage since the overall current flow through the solar cell, and therefore through the series resistance is zero. However, near the open-circuit voltage, the IV curve is strongly affected by the series resistance.
What is the characteristic resistance of a solar cell?
The characteristic resistance of a solar cell is the cell's output resistance at its maximum power point. If the resistance of the load is equal to the characteristic resistance of the solar cell, then the maximum power is transferred to the load, and the solar cell operates at its maximum power point.
