“…A possible alternative is to change the paradigm of the classical thermoelectric architecture, by proposing thin-film structures [255,256] able to convert thermal radial fluxes or Y-type structures [257]. In this context, it is important to notice the recent demonstration of the coupling effect between thermoelectric carriers and triboelectric charges, which can significantly increase the TEG performance of the same thermoelectric material [258]. However, these solutions are still far to be implemented in practical devices.…”

The increasing energy demand and the ever more pressing need for clean technologies of energy conversion pose one of the most urgent and complicated issues of our age. Thermoelectricity, namely the direct conversion of waste heat into electricity, is a promising technique based on a long-standing physical phenomenon, which still has not fully developed its potential, mainly due to the low efficiency of the process. In order to improve the thermoelectric performance, a huge effort is being made by physicists, materials scientists and engineers, with the primary aims of better understanding the fundamental issues ruling the improvement of the thermoelectric figure of merit, and finally building the most efficient thermoelectric devices.In this Roadmap an overview is given about the most recent experimental and computational results obtainedwithin the Italian research community on the optimization of composition and morphology of some thermoelectric materials, as well as on the design of thermoelectric and hybrid thermoelectric/photovoltaic devices.

Ionic thermoelectric materials have attracted increasing attention because of their high flexibility and high Seebeck coefficient. However, their insufficient thermoelectric performance and long‐standing processing limit their practical applications. To achieve exotic ionic thermoelectric materials, here, a graphene oxide (GO) modified acrylamide ionogel is designed with high thermoelectric performance and flexibility. Detailed structural characterizations confirm that the uniform dispersion of GO particles in the ionogel structure enables a power factor of 753.0 µW m−1 K−2 and a promising ZT value of 0.19. Additionally, the as‐prepared ionic thermoelectric thin film shows excellent flexibility, stretchability, and self‐adhesiveness. An integrated device, assembled by the as‐prepared ionogel films, can generate an optimal output power density of 1.32 mW cm−2 with a temperature difference of 20 K, indicating great potential for wearable electronics. This work provides insight for searching long‐term, high‐performance ionic thermoelectric materials.

Photo‐thermo‐electric (PTE) technology is a simple but sustainable method that directly converts solar energy into electricity. However, the manufacturing of flexible and breathable PTE generators for practical applications, such as intelligent wearable and self‐powered sensors, poses significant challenges due to the rigid thermoelectric materials and unbreathable substrates. Here, a highly‐flexible and breathable photo‐thermal‐electric membrane (FB‐PTEM) is developed by magnetron sputtering (MS) on a photo‐thermal nanofiber membrane. A single unit of FB‐PTEM produced an open‐circuit voltage of 0.52 V under 1 sun (100 mW cm−2) and 0.2 V under LED illumination, making it suitable for all‐weather use. The photo‐thermal nanofiber membrane exhibited high photo‐thermal conversion capacity of reaching 70 °C within 50 s under 1 sun irradiation. The FB‐PTEM with a thickness of 0.35 mm achieved a self‐temperature difference of 20.6 °C under 1 sun with the low thermal conductivity of the nanofiber membrane. Furthermore, it has a vapor permeability of 14.6 kg m−2 d−1 due to the inherent high porosity of the nanofiber membranes. The FB‐PTEM demonstrates great potential for the development of highly flexible thermoelectric materials, as it encompasses various advantageous features such as self‐temperature difference, lightweight design, high breathability, and all‐weather suitability.
