Title:
ELECTRICITY STORAGE DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/168493
Kind Code:
A1
Abstract:
An electricity storage device (30) is provided with: a first oxide semiconductor layer (14) having a first conductivity-type first oxide semiconductor; a first charging layer (16), which is disposed on the first oxide semiconductor layer (14), and which comprises a first insulating material and a first conductivity-type second oxide semiconductor; and a third oxide semiconductor layer (24) that is disposed on the first charging layer (16). The third oxide semiconductor layer (24) has hydrogen and a second conductivity-type third oxide semiconductor, and the percentage of the hydrogen to a metal constituting the third oxide semiconductor is 40 % or more. The electricity storage device capable of increasing electricity storage capacity per unit volume (weight) is provided.
