We considered that the large scale experimental database was effective for supplementing the intuition and experience of researchers. We have constructed experimental database with the composition and thermoelectric properties of Pb-(Te,Se,S) and SnTe thermoelectric materials of 453 samples. We improved the efficiency of searching for high performance thermoelectric materials by searching for unexploited composition by this experimental database and first-principle calculation. We found I-doped SnTe was a promising thermoelectric material with ZT~1.19.
