“…Tin dioxide (stannic oxide) has excellent features of a broad band-gap of well-nigh 3.6 eV [1], highrise optical visible transmission, infrared reflection and electrical conduction [2], small expense, superior mechanic strength and insistence under peripheral influences [3,4]. The stannic oxide is a dielectric material, but the non-stoichiometry resulted from O vacancies or Sn interstitials brings an n-type conductivity property [2]. These features make it useful for solar cells, li-ion batteries, light emitting diodes, gas sensors, architectural windows [5,6].…”

This work presents that the impact of Sb-additive on the crystalline, morphological, optical, and electrical features of SnO2. Sb-incorporated samples were fabricated on glass substrates with spray pyrolysis. Pyramidal and polyhedron shaped tetragonal Sb-introduced SnO2 grains were identified with XRD and SEM analysis. The degenerate n-type character for films was determined by electrical and optical characterizations. The resistivity and sheet resistance values initially decreased with Sb-content until 1.5 wt. %, then they increased with further Sb-level. However, carrier concentration increased with 2.5 wt. % Sb-contribution, then it started to goes down with 3.5 wt. %. The optical band-gap values of samples had a decreasing tendency with Sb-doping. From the results obtained in the present study, it is said that Sb-incorporated tin oxide films can be utilized in optoelectronic implements.

“…However, the electrical conductivity of FTO remains lower than the ∼10 4 S/cm of tin-doped indium oxide (ITO) [8]. Generally, the electrical properties of SnO 2 films depend on the sizes of grains [9], and doping with Ta [10], Sb [11], or F [12,13,14]. Fluorine is a preferred dopant to improve the electrical conductivity of SnO 2 films and retain the crystal structure because of the similar ionic radius between F − (1.33 Å) and O 2 ⁻ (1.32 Å).…”

Fluorine-doped tin oxide (FTO) thin films were deposited on glass substrates using ultrasonic spray pyrolysis (USP) at a fixed substrate temperature of 400 °C and various Fluorine/Tin (F/Sn) atomic ratios of 0, 0.1, 0.5, and 1.0. Effects of F/Sn atomic ratios on structural-morphological, compositional, electrical, optical, and nanomechanical properties of the FTO thin films were systematically studied. The FTO films exhibited a tetragonal structure with preferred orientations of (110), (200), and (211), and polycrystalline morphology with spear-like or coconut shell-like particles on the surfaces. The presence of F-doping was confirmed by XPS results with clear F1s peaks, and F-concentration was determined to be 0.7% for F/Sn = 0.1 and 5.1% for F/Sn = 0.5. Moreover, the resistivity of FTO films reduced remarkably from 4.1 mΩcm at F/Sn = 0 to 0.7 mΩcm at F/Sn = 1, primarily due to the corresponding increase of carrier concentration from 2 × 1020 cm−3 to 1.2 × 1021 cm−3. The average optical transmittance of the films prepared at F/Sn of 0–0.5 was over 90%, and it decreased to 84.4% for the film prepared at F/Sn = 1. The hardness (H) and Young’s modulus (E) of the FTO films increased when the F/Sn ratios increased from 0 to 0.5, reaching maximum values of H = 12.3 ± 0.4 GPa, E = 131.7 ± 8.0 GPa at F/Sn = 0.5. Meanwhile, the H and E reduced considerably when the F/Sn ratio further increased to 1.0, following the inverse Hall-Petch effect approximately, suggesting that the grain boundary effect played a primary role in manipulating the nanomechanical properties of the FTO films. Furthermore, favorable mechanical properties with large H/Ef and H 3 / E f 2 ratios were found for the FTO film prepared at F/Sn = 0.5, which possessed high crystallinity, large grain size, and compact morphology.

The shortage of fossil energy and the environmental pollution caused by its use promote the development of renewable clean new energy. Energy storage devices are the best choice to convert and store them into efficient and convenient electric energy, and the light weight of the conductive film plays an important role in energy storage devices. Conductive films as electronic conduction layers have become a research hotspot due to their high electronic conductivity, environment‐friendly, low cost, flexibility, transmittance, high chemical stability, good film forming, and excellent mechanical properties. The material selection, conductivity, preparation methods, and adhesion to the substrate of the conductive films all affect the performance of the energy storage devices. Herein, the conductive properties of conductive films of metal materials, carbon materials, conductive polymers, metal oxides, metal nitrides, and other compounds are reviewed. The application of conductive films as electron conduction layers in solar cells, supercapacitors, lithium‐ion batteries, and solid aluminum electrolytic capacitors is analyzed. The future development trend of conductive films in energy storage devices is prospected.
