Design, Fabrication and Investigation of Semitransparent Thermoelectric Cells Based on Graphene

摘要

The design, fabrication and investigation of the graphene-In-SnO2 (indium tin oxide (ITO)) based bilayer semitransparent thermoelectric cells are described. The cells were fabricated by encapsulating thegraphene powder in the form of narrow strips on the transparent flexible plastic substrates covered byITO. Between the parallel graphene strips, there were transparent ITO strips of the same width. Thisstructure made the thermoelectric cells semitransparent. It was observed that Seebeck coefficient andfigure of merit of the thermoelectric cell increased with temperature. The output voltage of the cellsalso increased with increase in gradient of temperature. The obtained results may be used for thedevelopment of the semitransparent solar thermoelectric cells because this technology is cheaper andsimple as compared to semitransparent solar cells technologies.
