Abstract

The aim of this paper is the investigation of electrical and acoustic properties of solar cells assembled into modules, before and after forced and accelerated ageing. It has been shown that impedance spectroscopy measurement and characterization is an important tool to reveal the degradation changes due to high voltage stress and environmental stress. The parameters of photovoltaic (PV) cells and modules have been derived from electric and acoustic measurements. Important differences between the results of measurements have been found before and after the PV cells and modules underwent the stressing.
