“…Therefore their absolute values and the seemingly large differences between quasi stationary and dynamic analysis must be treated with caution. Still, in the voltage range from V@P max to V oc the capacitance, and in particular the dynamic capacitance (2), is at its maximum [8]. Also, since the data are recorded during the decay of the light pulse and the strongest rate of change of the intensity happens when the module is at the highest range of voltage, the influence of the capacity will be strongest in this phase.…”

A measurement scheme is presented for obtaining the physical parameters of a photovoltaic module with a short light flash. The module is under constant load and voltage and current are recorded during the decaying illumination intensity of the flash. The physical parameters are extracted by means of the one diode model including voltage dependent capacitance. From these parameters the stationary current-voltage curve is reconstructed for a wide range of illumination levels.

“…It underestimates I sc by 1.7% and I@P max by 0.75%. The difference is especially small with P max , so that for purposes of power rating the quasi stationary method is well justified, and has been employed in a multi-flash scheme already quite some time ago [2].…”

“…The utilization of a pulsed Xe flash is important not only for the measurements of concentration solar cells in a lab, but also is an inexpensive way of measuring large area modules, and it is also easily transportable (for example during a spacecraft test qualification campaign) . The Xe flash spectrum differs from the AM0 standard, and it is difficult to perform a spectral distribution measurement due to the pulse short duration and the extended wavelength range associated to multijunction cells spectral response .…”

This paper presents a method to predict the I-V characteristic of triple junction InGaP/GaAs/Ge solar cells when different illumination spectra are used, and it is based on the measurement of a set of commercial isotype cells together with numerical simulations. The study includes the utilization of continuous and pulsed light sources. Several spectra were considered for the continuous light sources, where different subcells limit the current of the tandem cell. For pulsed light sources, a dynamical analysis was carried out by simulating a triple junction cell through PSpice software. For the simulations, the subcell capacitances were estimated and introduced into an electrical model of the triple junction. When a fast pulse in the multiflash I-V measurement technique is used, dynamical effects associated with this kind of source were observed and accounted for by the simulations. It was established that the dynamical effects did not affect the I-V characteristics measured with this technique. Finally, the proposed method and analysis were successfully applied to the electrical characterization of the Aquarius/SAC-D Argentine satellite solar array modules.

“…Some have been documented in the literature [1][2][3][4][5][6] and several commercial systems are available for 1-sun testing, but none are made specifically for concentrator cells. Flash testers can be categorised as single flash or multi-flash.…”
