The series resistance (R s) of a solar cell is commonly represented as a constant resistance value. However, because of the distributed nature of series resistance, the effective lumped R s vary with current density and illumination intensity.
series resistance imaging techniques are further developed into "nonlinear R s EL" to meet the requirements of ever thinner solar cells with higher lifetimes in this article. 2. Theory The following methods utilize the model of independent diodes, i.e., every image pixel is connected to the terminal via an inde-pendent series resistance.
About 20 methods of determining the solar cell series resistance R s are reviewed. Their differences lie principally in: (i) experimental conditions (darkness or illumination, flash or constant illumination, static or dynamic mode, temperature conditions, frequential or non-frequential regime); (ii) number of diodes quoted in the solar cell ...
