Dye solar battery structure and manufacturing method of light absorption reaction layer thereof

Abstract

The invention relates to a dye solar battery structure and a manufacturing method of a light absorption reaction layer thereof. A base plate and a transparent base plate are arranged in a layering manner at a mutual interval; two electronic transmission layers are respectively arranged on a surface where the base plate is close to the transparent base plate; the light absorption reaction layer contains a light absorption reaction structure and a first lead which are all arranged on the surfaces of the electronic transmission layers of the transparent base plate; an antipode layer is arranged oppositely to the light absorption reaction layer; the light absorption reaction structure adopts a semiconductor layer with particles stacked from small to large; and dye molecules with different dimensions and different light wavelength absorption scopes are absorbed on the semiconductor layer and irradiated by subsequent light rays through the transparent base plate so as to result in current generated by potential difference, thereby not only improving the absorption efficiency of the light rays by adopting a three-dimensional structure, but also enlarging the frequency spectrum range absorbed by the light rays through the dye molecules with different wavelength scopes.

Description

technical field [0001] The invention relates to a dye solar cell structure and a method for manufacturing a light-absorbing reaction layer of the dye solar cell structure, in particular to a dye solar cell structure and a method for manufacturing the light-absorbing reaction layer for expanding the light wavelength absorption range. Background technique [0002] Dye solar cells, which use dyes to sensitize light to generate current, are a brand-new solar cell that has been developed recently, using dye molecules to absorb light to generate a potential difference, and then generate current. [0003] The substrate of the dye solar cell is usually a glass substrate, with two layers on the upper and lower layers, and the substrate can also be a transparent and bendable polymer foil; there is a transparent conductive oxide layer on the glass, usually made of carbon dioxide Tin (SnO 2 ), the conductive oxide layer is combined on the glass to become transparent conductive oxide (T...

Problems solved by technology

[0005] In the past, the general titanium dioxide has a single-layer structure. Later, in order to increase the conversion efficiency of dye solar cells, the technology of multi-layer titanium dioxide structure appeared, but they all have the same structure size and the same dye molecules, although the total number of dye molecules has greatly increased. amount, but identical dye molecules absorb only the same wavelength range of light
