“…This indicates that a small cation is needed in order to obtain an improvement in the PF. Doped SnO 2 films exposed to electrolytes can be found in different applications, such as ion intercalation systems 10,11 and dye-sensitized solar cells. 12,13 In these devices, electrolytes as the ones employed in our study are frequently used.…”

The performance of thermoelectric materials has been improved in the past few years by a significant reduction of the thermal conductivity, but this parameter has now reached its (amorphous) limit, which makes the enlargement of the power factor (PF) critical. Here we present a new concept, based on a hybrid system formed by a porous thermoelectric solid permeated by a liquid with an inert salt dissolved (electrolyte), which can be designed to significantly enhance the PF. The concept is demonstrated in an Sb-doped SnO2 porous film permeated with different inert salts (X+(BF4)−, X+ = Li+, Na+, K+) dissolved in 3-methoxypropionitrile (3-MPN). A 61.9% average decrease in the electrical resistivity without a significant variation of the Seebeck coefficient was found in the case of 1 M LiBF4 in 3-MPN. As a result, the PF was remarkably increased 3.4 times. On the other hand, 1-butyl-3-methylimidazolium (BMI+Y–, Y– = I–, BF4 –) ionic liquids were also employed as electrolytes. Using the BMII ionic liquid, the electrical resistivity showed a more significant average decrease of 82.5%; however, the absolute value of the Seebeck coefficient was reduced by 35%, finally resulting in an average enhancement of 2.4 times of the PF. The large enhancements achieved are attributed to the modification of the electrostatic environment of the porous solid by the ions in the electrolyte at the solid–liquid interface. These results establish a new strategy for the significant improvement of the PF which is not restricted to certain materials and can be potentially applied widely.

“…It can be seen that for the FT-IR spectrum of the dried ATO-7 precursor, the adsorption peaks at 560 cm -1 and 680 cm -1 can be ascribed to the terminal oxygen vibration of γ Sn-OH and functional groups of γ O-Sn-O , respectively[34]. The absorption peak at 3400 cm -1 is O-H stretching vibration[34], arising from absorbed water of ATO-7 precursor. The band at 1622 cm −1 corresponded to N-H in-plane bending vibration are supposed to…”

“…Several of its potential applications, such as its use as an electrode for dye-sensitized solar cells and electrochromic devices, (14,15) a catalyst in chemical reactions, (16) a varistor, (17) and a material for gas sensor, (18) were previously reported. SnO 2 is an n-type semiconductor with high electrical conductivity, so this material is also expected to be suitable for use in TE devices.…”

The thermoelectric (TE) properties of SnO 2 codoped with Sb and Zn were investigated. Polycrystalline ceramics of n-type SnO 2 -based semiconductors (Sn 1−2x Sb x Zn x O 2 , x = 0, 0.01, 0.03, 0.05, 0.07) were prepared by reactive spark plasma synthesis followed by thermal treatment at a temperature of 1123 K. X-ray diffraction (XRD) analysis showed that most of the XRD peaks could be assigned to peaks of the pure SnO 2 phase. The x = 0.05 and 0.07 samples showed the formation of a Zn 2 SnO 4 secondary phase along with the main SnO 2 phase. Microstructural analysis by scanning electron microscopy showed that the average grain sizes of the Sb and Zn codoped samples were larger than that of the undoped sample. The highest TE power factor in this study was 1.20 × 10 −4 Wm −1 K −2 , which was comparable to the previously reported value for the sample synthesized by conventional normal pressure sintering at 1573 K. The synthesis method we describe here is very effective for the low-temperature synthesis of SnO 2 -based TE ceramics.
