Abstract

A self-driven power generation module and a manufacturing method thereof are provided. The self-driven power generation module includes an upper structure, a lower structure, and a charge accumulation layer. The upper structure includes a first encapsulating layer, a first supporting layer, and a first electrode layer. The first supporting layer contacts the first encapsulating layer. The first electrode layer contacts the first supporting layer. The lower structure is spaced apart from the upper structure. The lower structure includes a second encapsulating layer, a second supporting layer, a second electrode layer, a third supporting layer, and a third electrode layer. The third supporting layer is disposed on the second encapsulating layer and spaced apart from the second supporting layer. The third electrode layer is disposed on the third supporting layer. The charge accumulation layer is disposed between the upper structure and the lower structure.

First claim

What is claimed is:

1 . A self-driven power generation module, comprising:
an upper structure, comprising:
a first encapsulating layer;
a first supporting layer contacting the first encapsulating layer; and
a first electrode layer contacting the first supporting layer;
a lower structure spaced apart from the upper structure, and the lower structure comprising:
a second encapsulating layer;
a second supporting layer disposed on the second encapsulating layer;
a second electrode layer disposed on the second supporting layer;
a third supporting layer disposed on the second encapsulating layer and spaced apart from the second supporting layer; and
a third electrode layer disposed on the third supporting layer; and
a charge accumulation layer disposed between the upper structure and the lower structure.

2 . The self-driven power generation module of claim 1 , further comprising:
an electronic component electrically connected to the second electrode layer and the third electrode layer.

3 . The self-driven power generation module of claim 1 , wherein the third electrode layer is located outside a downward projection area of the charge accumulation layer.

4 . The self-driven power generation module of claim 1 , wherein the charge accumulation layer is disposed on a lower surface of the first electrode layer.

5 . The self-driven power generation module of claim 4 , wherein the lower surface of the first electrode layer defines an unexposed area and an exposed area, the charge accumulation layer covers the unexposed area, and the exposed area faces the third electrode layer.

6 . The self-driven power generation module of claim 1 , wherein the charge accumulation layer includes a high electronegative polymer material.

7 . The self-driven power generation module of claim 1 , wherein an upper surface of the third electrode layer is lower than an upper surface of the second electrode layer.

8 . The self-driven power generation module of claim 1 , wherein the third electrode layer is spaced apart from the second electrode layer.

9 . A manufacturing method of a self-driven power generation module, comprising:
providing a first laminated structure, a second laminated structure and a third laminated structure, wherein the first laminated structure includes a first supporting layer, a first electrode layer formed on the first supporting layer, and a charge accumulation layer formed on the first electrode layer, the second laminated structure includes a second supporting layer and a second electrode layer formed on the second supporting layer, and the third laminated structure includes a third supporting layer and a third electrode layer formed on the third supporting layer; attaching the first laminated structure on a first encapsulating layer to form an upper structure; attaching the second laminated structure and the third laminated structure on a second encapsulating layer to form a lower structure; and enabling the charge accumulation layer to face the second electrode layer of the second laminated structure and the upper structure to be spaced apart from the lower structure to obtain the self-driven power generation module.

10 . The manufacturing method of claim 9 , further comprising:
electrically connecting the second electrode layer and the third electrode layer through an electronic component.
