From: Realizing high-ranged thermoelectric performance in PbSnS2 crystals
a ZT values of undoped and Cl doped PbSnS2 crystals, the inset shows ZT values of the optimal Cl doped PbSnS2 crystal calculated according to Dulong-Petit law, Debye model and the experimental DSC data. Error bars are ±10%. b The comparison of ZT values between PbSnS2 and SnS crystals23,24 along in-plane and out-of-plane directions. c Output power P, the inset shows the mini-PEM test. d Power generation efficiency η for single-leg device based on the optimal Cl doped PbSnS2 crystal. Comparison of single-leg power generation efficiency between the optimal Cl doped PbSnS2 crystal in this work and and p-type SnS crystal16.
