Document Type and Number:
WIPO Patent Application WO/2021/095403
Kind Code:
A1
Abstract:
[Problem] To provide a method that is for controlling work function of an electrode and that enables reduction of production costs of a power generation element. [Solution] A power generation element according to one embodiment of the present invention comprises: a first electrode 11; a second electrode 12 which is disposed so as to face the first electrode 11 across a gap; and an intermediate part which is provided within the gap. The intermediate part includes nanoparticles 14. The nanoparticles 14 have a work function that falls between the work function of the first electrode 11 and the work function of the second electrode 12. The first electrode 11 and the second electrode 12 are both made of the same conductive material, and the second electrode 12 is subjected to annealing so as to change the work function φA of the second electrode 12 from the level of the work function φK of the first electrode 11 to a level that exceeds the work function φN of the nanoparticles 14.
