“…Therefore, the parameters can be extracted locally from two regions: 1) G p , n 2 and I 02 by vertical optimization of the low voltage region fitting equation (54) to the measured current; and 2) R s , n 1 and I 01 by by lateral optimization of the high voltage region fitting equation (56) to the measured voltage. Figure 22 also includes the original and the parameter values extracted by this method.…”

This article presents an up-to-date review of several methods used for extraction of diode and solar cell model parameters. In order to facilitate the choice of the most appropriate method for the given particular application, the methods are classified according to their lumped parameter equivalent circuit model: singleexponential, double-exponential, multiple-exponential, with and without series and parallel resistances. In general, methods based on numerical integration or optimization are recommended to reduce the possible uncertainties arising from measurement noise.

The transparent top contact layer of a solar cell is a distributed resistance that cannot be easily represented mathematically. We have used a finite element model to calculate the current distribution in this transparent layer. The calculation gives the voltage drop along the layer as well as the resulting reduction in the current generated in the active layer of the solar cell. IV curves generated by the model are used to investigate various methods of experimentally determining series resistance. It is found that the suns-V oc method is the most accurate. A fit of the finite element model to experimental IV data from an organic solar cell is used as an example of obtaining solar cell model parameters.

“…The Lambert-W function has several uses in physical and engineering applications [9]- [13]. In [11], the Lambert-W function is used for the purpose of diode parameters determination in diode I-U curve fitting. In [12], the Lambert-W function is integrated to a tolerance optimization problem in the context of manufacturing operations.…”

In some fading environments, there may not be a feedback link sufficiently fast to convey the full channel state information (CSI) to the transmitter. This paper considers a power allocation problem for cooperative relay networks, where the transmitter node knows only the channel distribution information (CDI). The goal is to maximize the ergodic capacity. The application of the Lambert-W function to obtain a closed-form solution for the underlying power allocation problem constitutes the principal contribution of this paper. By using the Lambert-W function, power allocation can not only be expressed in closedform but it can also quickly be determined without resorting to complex algorithms since a number of popular mathematical softwares, including Matlab, contain the Lambert-W function as an optimization component.
