Enhanced Thermoelectric Power Factor in the Cu2se System by the Incorporation of (Go/Mwcnt)
View through CrossRef
The current study examines the transport capabilities of the thermoelectric material of Cu2Se, and its GO (Graphene oxide) /MWCNT (Multi-Walled Carbon Nano Tubes) composites manufactured using a cost-effective and straightforward chemical reduction and a simple mechanical grinding process. Raman spectra, FESEM pictures, and the XRD peak intensity of the composites all showed the existence of (GO/MWCNT) in the as-prepared samples. The power factor rose with the addition of (GO/MWCNT), reaching maximum values of 800μ W/mK2 and 1200μ W/mK2 at 450 ºC for Cu2Se-GO and Cu2Se-MWCNT, respectively. According to the findings, the highest thermopower of the Cu2Se-MWCNT composite is around 120% greater than that of bare Cu2Se. This article outlines an efficient and inexpensive process for producing carbon-related composite thermoelectric materials and a viable technique for increasing the power factor to enhance synergistic thermoelectric performance.
