Accurate series resistance measurement of solar cells

The series resistance (Rs) of a solar cell is commonly represented as a constant resistance value. However, because of the distributed nature of series resistance, the effective lumped Rs vary with current density and illumination intensity. Treating Rs as a constant is usually insufficient for an accurate analysis of its J–V curve. This work first presents a review of the …
