Analysis of fill factor losses in thin film CdS/CdTe photovoltaic devices

In this paper, CdS/CdTe solar cells with conversion efficiency values of η = 5.1, 3.6, 3.5, and 2.9% are analyzed and the effects of the device parameters, such as the diode ideality factor (n), the saturation current-density (Jo), and the series resistance (Rs,) on the fill factor, both in the...
