The main objective of the present work is to develop and prove a theoretical explanation based on the Extended Non-Equilibrium Thermodynamics (ENET) for the hysteretical thermoelectric behavior observed in certain thinfilm photovoltaic materials. The ENET introduces dissipative fluxes in the entropy balance that could explain this behavior. To verify this explanation from a numerical point of view, results are generated using a Finite Element (FE) formulation based on the ENET and already developed in previous publications by the authors. In addition, an identification Inverse Problem (IP) is formulated; a cost function is defined as the quadratic difference between experimental and numerical results and the IP is solved minimizing the cost function using genetic algorithms. The conclusion is that the loop-like distributions are due to energy dissipation introduced by dissipative fluxes that are closely related with relaxation times. Also, the FE-IP combination permits to find an approximated characterization of properties for several materials from single experimental curves. Finally, several numerical simulations are proposed for laboratory experiments to further validate

“…However, the P F s of those thermoelectric sulfides are not high for providing the ideal zT s. For example, the best performance material Cu 1.97 S only has a P F near 8 µWcm −1 K −2 at 1000 K. Thus, an interesting approach to give a high zT value is to search a thermoelectric sulfide with intrinsic large P F . Palladium sulfide (PdS), which belongs to transition-metral sulfide, has potential applications in semiconducting, photoelectrochemical, and photovoltaic fields, because of its ideal band gap of 1.6 eV [13][14][15] . Furthermore, it also has several potential device applications in catalysis and acid resistant hightemperature electrodes [16][17][18] .…”

A suite measurements of the electrical, thermal, and vibrational properties are conducted on palladium sulfide (PdS) in order to investigate its thermoelectric performance. The tetragonal structure with the space group P 42/m for PdS is determined from X-ray diffraction measurement. The unique temperature dependence of mobility suggests that acoustic phonons and ion impurity scattering are two dominant scattering mechanisms within the compound. The obtained power factor of 27 µWcm −1 K −2 at 800 K is the largest value in the remaining transition-metal sulfides studied so far. The maximum value of the dimensionless figure of merit is 0.33 at 800 K. The observed phonon softening with temperature indicates that the reduction of the lattice thermal conductivity is mainly controlled by the enhanced lattice anharmonicity. These results indicate that the binary bulk PdS has promising potential to have good thermoelectrical performance.

“…Pd 4 S, although not studied well in its pure phase, is believed to be the primary component in catalysts that remove Hg from coal gas streams,16 and catalysts that are resistant to acidic solutions used for the electrolytic deposition of Cu while manufacturing circuit boards 17. It is also projected to be a material for high‐temperature electrodes,18 as well as in solar cells 19, 20. Conventional synthesis of palladium sulphides is done by heating the elements in requisite proportions in an evacuated tube, grinding, and annealing the obtained powder product for several days 21, 22.…”

A simple, one‐step process to synthesize Pd4S films is reported here along with their characterization using X‐ray diffraction, electron microscopy, and electrical measurements. The synthesis involves thermolysis of a single‐source precursor, namely palladium alkanethiolate, in H2 atmosphere at 250 °C for 3 h. The films are highly conducting and resistant to strong acidic, alkali, and oxidizing environments. The precursor allows patterning of the Pd4S films by electron beam lithography and micromolding, an attribute that has been employed in making chemically resistant electrodes and etch masks. The conversion of palladium thiolate to other sulfide phases is also achieved.
