“…Despite extensive research in the field of cardo aromatic polyethers carried out by scientists from different countries, there is still no information on the study of the electrical properties of these polymers by other groups. These polymers provided an electrical contact with TCO and metal with low resistivity (less than 1 mΩ cm 2 ) [ 17 ]. The use of these polymers made it possible to obtain good adhesion even with round copper wires without the use of low-temperature In: Sn solder.…”

The mechanism of charge carrier transport in the indium tin oxide (ITO)/polymer/Cu structure is studied, where thin films of copoly(arylene ether ketone) with cardo fluorene moieties are used. This copoly(arylene ether ketone) is non-conjugated polymer which has the properties of electronic switching from the insulating to the highly conductive state. The dependence on the polymer film thickness of such parameters as the potential barrier at the ITO/polymer interface, the concentration of charge carriers, and their mobility in the polymer is studied for the first time. The study of this system is of interest due to the proven potential of using the synthesized polymer in the contact system of a silicon solar cell with an ITO top layer. The parameters of charge carriers and ITO/polymer barrier are evaluated based on the analysis of current–voltage characteristics of ITO/polymer/Cu structure within the injection current models and the Schottky model. The thickness of the polymer layer varies from 50 nm to 2.1 µm. The concentration of intrinsic charge carriers increases when decreasing the polymer film thickness. The charge carrier mobility depends irregularly on the thickness, showing a maximum of 9.3 × 10−4 cm2/V s at 210 nm and a minimum of 4.7 × 10−11 cm2/V s at 50 nm. The conductivity of polymer films first increases with a decrease in thickness from 2.1 µm to 210 nm, but then begins to decrease upon transition to the globular structure of the films at smaller thicknesses. The dependence of the barrier height on polymer thickness has a minimum of 0.28 eV for films 100–210 nm thick. The influence of the supramolecular structure and surface charge field of thin polymer films on the transport of charge carriers is discussed.

“…One promising method of the formation of such kind of contact involves the use of cardo poly(arylene ether ketones) (PAEKs) with fluorene side groups, which are unique thermoplastic polymer materials. PAEKs are used as adhesives for securing a metal grid to TCOs and forming an electrical contact with a low resistivity (lower than 1 m • cm 2 ) [2]. These polymers switch spontaneously from a dielectric state to a highly conductive one in the course of low-temperature lamination (below 220 • C) under a slight pressure excess (up to 1 atm).…”

The mechanism of charge carrier transport in the tin doped indium oxide (ITO)/polymer/Cu structure was studied for the first time, where thin films of poly(arylene ether ketone), which has the properties of electronic switching from the insulating to the highly conductive state, were used. The system under study can be considered as a model of a current-collecting contact system in a solar cell with ITO top layer. Keywords: transparent conducting oxide, conducting polymer, contact system, activation energy, tunneling.
