Problems solved by technology

However, in order to manufacture electrode materials with highly periodic photonic crystal structures, laser etching technology combined with dry etching technology can only be used to manufacture samples individually in the laboratory, and the cost is high and cannot be mass-produced. Broad application is limited

Abstract

The invention discloses a preparation method for a photonic crystal structure film electrode of a dye solar cell in the technical field of solar cells. A photonic crystal structure positive template structure is introduced into the solar cell and is packaged combined with a pyridine complex dye of ruthenium so as to form the photonic crystal dye solar cell with improved efficiency. A photonic crystal structure positive template is prepared through emulsifier-free emulsion polymerization and a vertical deposition method, and a titanium dioxide photonic crystal reverse template is prepared through a sandwich treatment topology, thereby improving an electrode structure of the traditional dye cell, exceeding the limitation of laboratory photo-etching processing and enhancing the application potential thereof. The prepared photonic crystal structure film electrode takes a three-dimension ordered anatase type titanium dioxide hole arranged by an inverse opal structure as the electrode of the dye solar cell, the hole diameter of film materials thereof ranges from 50nm to 500nm, and the thickness ranges from 0.5 micron to 40 microns, thereby enlarging the specific surface area combined with the dye and having higher short circuit current and filling factors.

Description

Technical field [0001] The invention relates to a preparation method in the technical field of solar cells, in particular to a preparation method of a photonic crystal structure thin film electrode for dye solar cells. Background technique [0002] As one of the protagonists of the third-generation solar energy technology, thin-film solar cells are different from traditional crystalline silicon cells. They have the advantages of low cost, light weight, sufficient raw materials, and ability to work under low light. In addition to CIGS (CuInGaSe), CdTe and amorphous / microcrystalline silicon and other thin film batteries that have begun mass production, Swiss M. The Dye Sensitized Solar Cells (DSSC) developed by the professor's research team is unique with its abundant and cheap raw materials and simple production. It replaces the plate electrode with a porous titanium dioxide electrode, and introduces metal ruthenium (Ru) bipyridine complex dye as a donor that is excited by photon...
