Abstract
This paper is focused on the dynamic characterization of the silicon wafer-based photovoltaic cells. The open circuit voltage decay of the solar cell under dark and illumination conditions are observed and analysed to model the dynamic parameters at different voltage bias. The procedure is developed for near real-time analysis and thus used to investigate parameter variation of the cell under partial-shading condition. The results obtained are compared and further validated against values from frequency domain analysis using Impedance spectroscopy (IS). Analysis of results show that with a test duration of 1sec, an estimate of the carrier life time and R-C parameters can be made. This assessment can be used as a basis to estimate the charge extraction and recombination efficiency of different cells/modules in real-time applications, as well as, cell/string level fault detection in grid-applications.
