POWER GENERATION MATERIAL, POWER GENERATION ELEMENT, AND POWER GENERATION SYSTEM

WIPO Patent Application WO/2017/111161

A1

Provided are a power generation material with which it is possible to obtain exceptional power generation efficiency, a power generation element comprising the power generation material, and a power generation system obtained using the power generation element. The power generation element is obtained from the power generation material, which comprises a solid solution of a first dielectric that has the relaxer perovskite crystal structure represented in general formula (1), and a second dielectric comprising a ferroelectric material. The power generation system is obtained using the power generation element. Pb (B1 xB2 1-x) O3 (1) (where: B1 indicates at least one element selected from the group consisting of Mg, Zn, Yb, Ni, Se, In, and Sc; B2 indicates at least one element selected from the group consisting of Nb, Ta, and W; x indicates an atomic ratio within the numerical range 0
