Article Title: Dual PCM integrated thermoelectric generator for harvesting energy from ambient temperature variations

doi: 10.1039/d6ra02643e

Figure Lengend Snippet: Schematic of the proposed dual PCM-TEG harvester. (a) Cross-sectional view of the system, showing a thermoelectric generator (TEG) with n- and p-type thermolegs, sandwiched between two distinct PCMs, each doped with copper wool and graphene nanoplatelets (GnP). (b) Working principle of the system as an ambient temperature-driven energy harvesting unit. The red curve represents ambient temperature fluctuations, while the blue and yellow curves indicate temperature variations across the TEG.

Article Snippet: Two carbon additives were investigated: μGr (ProGraphite GmbH) and graphene nanoplatelets (GnP, Nanografi), due to their high intrinsic thermal conductivity.

Figure Lengend Snippet: (a) D- and G-band region Raman spectra of pristine graphite, exfoliated graphene, and CIG nanoscaffolds, normalized at the G-band (the D- and G-bands are observed between 1200 and 1700 cm –1 ). The 2D-band region Raman spectra of (b) pristine graphite, (c) exfoliated graphene, and (d) CIG nanoscaffolds. The 2D-band region Raman spectrum of the CIG nanoscaffolds is fitted by a Lorentzian function. The analysis is carried out on a Si-wafer surface by using a laser excitation of 514 nm.
