The Development of the I-V Measurement by Pulsed Multi-Flash, and the Effectiveness
In order for the device to measure the I-V characteristics of the photovoltaic (PV) module to be used in the PV module assembly line, easy handling of the module, improvement of measurement accuracy, and reduction of the measuring time are strongly requested. We developed the solar simulator with several milliseconds flat pulsed light of multi flashes and accomplished the improvement of measurement accuracy, and the reduction of the measuring time. Both I-V measuring device and measuring method we developed are also effective in estimating the characteristics of response, light induced change, and being newly developed PV modules
Using Various Pulse Durations and Reference Cells on Long-Pulse Solar Simulator for CIGS Thin-Film PV Module Performance Measurements
In this paper the influences of various pulse durations and reference cell types on CIGS thin-film PV module performance measurements with a long-pulse solar simulator are presented. Pulse duration between 50ms to 1050ms is chosen by long-pulse solar simulator in the study. The differences of module performance caused by using monolysilicon and polysilicon reference cells with/without EVA, respectively, to monitor simulator irradiance are compared. Furthermore, measurements uncertainty of testing laboratory is discussed in study for estimating the capacity of PV module indoor testing.
The mini-flasher: a solar array test system
Abstract The mini-flasher has been developed to provide a simple and mobile instrument to control solar array basic functionality and use comparative measurements to detect damages. The paper recalls the technological evolution which led to flashers or LAPSS, their complexity, and their accuracy which was countered by loss in operational flexibility. The mini-flasher principles of operation are briefly given as well as a summary of the user manual and an example of the result. Although the system was developed in the spacecraft technology environment, its mobility probably makes it a useful tool for the field verification of terrestrial solar arrays performance.
