Abstract

The development of CdS/CdTe solar cells on Upilex-S foils coated with a semitransparent indium tin oxide (ITO) is reviewed in this article. The basic manufacturing technique includes the chemical-bath deposited CdS and the close-spaced sublimated CdTe, the solution-CdCl2 treatment, and an evaporated Ni contact. The devices have been investigated using the current-voltage (I-U) characteristics and the capacitance-voltage (C-U) measurements in order to define the transport mechanism in a photovoltaic device and the basic electronic parameters. ITO/CdS/CdTe photovoltaic cells with conversion efficiencies exceeding 4% have been developed on polyimide foils with the area of 1.7 cm2. Both I-U and C-U characteristics of the poly/ITO/CdS/CdTe cell show the typical behavior of the two-diode model..
