Summary: This article discusses the development of a z-type thermoelectric element with a direct electrical junction based on dissimilar oxide conductors, Ca0.9Bi0.1MnO3 (n-type) and Ca2.7Bi0.3Co4O9 (p-type). A thermoelectric z-element was fabricated using hydrostatic pressing and an interconnector based on an oxide composite and silver particles. The microstructure of the thermoelectric legs was studied using electron microscopy. Measurements of resistivity and Seebeck coefficient were conducted, and the estimated power factor was calculated for different ceramic samples. The maximum output power of the manufactured thermoelectric module reached 1.1 mW at a temperature gradient of 580 degrees C and a cold side temperature of 37 degrees C. Additionally, simulations were performed to determine the resistance of interfaces between the thermoelectric material and interconnector. The study highlights the potential of hydrostatic pressing in producing complex-shaped thermoelectric elements without vulnerable metal-semiconductor electrical connections in oxide thermoelectric modules.

Summary: This research investigates the transport and thermoelectric behaviors of CZTSSe thin films. Both p-type and n-type films were successfully synthesized to comprehensively study the characteristics of CZTS. The conductivity and carrier concentration increased with higher Cu contents, changing the conducting type from p-type to n-type. The band gap decreased and the full width at half maximum increased with increased Cu content. The proposed n-type CZTS with Cu/Zn + Sn tilde 1.01 and Zn/Sn tilde 1.1 had the best power factor.

Summary: This study determines the oxygen vacancy concentration (delta), electrochemical reaction, and durability of LaNiO3-delta, a perovskite-type oxide, as functions of temperature (773-1073 K) and oxygen partial pressure. The results show that LaNiO3-delta has a higher oxygen partial molar enthalpy at delta approximate to 0, indicating the ease of oxygen vacancy formation. The electrochemical properties and durability of LaNiO3-delta were investigated, and impedance spectra analysis revealed three components of the electrode reaction. Further experiments demonstrated the stable performance of the LaNiO3-delta porous electrode under specific conditions.
