     conventional thermoelectric generators (tegs) use single p- and n-doped legs for thermoelectric energy harvesting. we explore a concept using thermoelectric pn junctions made from densified silicon nanoparticles. the nanoparticle powder was synthesized in a microwave plasma reactor using silane, diborane, and phosphine as precursors. to achieve a bulk sample with a pn junction, a layer of boron-doped nanoparticle powder was stacked on a layer of phosphorus-doped powder and compacted by current-activated pressure- assisted densification. to use the pn structure as a teg, a temperature gradient was applied along the pn junction. it is expected that this temperature gradient leads to electron–hole pair generation and separation in the junction, and diffusion of the charge carriers. a reference method was used to characterize the open-circuit voltage of the pnjunction teg.
