For the first time, the thermoelectric properties of cement/single-walled carbon nanotube (SWCNT) nanocomposites with over 3, 7, 14 and 28 days of hydration are reported, while a thermoelectric generator device (TEG) is fabricated utilising the material with the highest achieved power factor (PF).

We used an inexpensive and effective way to improve the thermoelectric properties of PEDOT:PSS, which has the highest power factor of up to 330.597 μW m−1. Overall data shows that the Ni film is relatively stable as an n-type material, with Ni as an n-leg in the thermoelectric module. We fabricated a thermoelectric generator to explore the photothermal conversion process of solar energy.
