Output parameters of photovoltaic cells at ultrahigh radiant fluxes

Structure defects in PV cells can be identified through I-V curve parameters: short circuit current, open circuit voltage, fill factor and efficiency.

Description
Summary:Structure defects in PV cells can be identified through I-V curve parameters: short circuit current, open circuit voltage, fill factor and efficiency. In converting high density radiant fluxes, structure heating affects significantly these parameters. For this reason constant temperature (25°C) is a necessary condition for correct characterization. In this paper, a method for recording optical and electronic parameters of PV cells in regimes of converting high density radiant fluxes, which excludes the effect of radiative heating of a device, is presented.
