Problems solved by technology

Although there have been breakthroughs in improving the electrode structure and doping metals, as far as we know, no one has proposed to dope nanometer-sized noble metal particles onto the surface of photonic crystal titanium dioxide electrodes with inverse opal structures. Improving battery efficiency through metal surface plasmon resonance combined with coupling effects from periodic dielectric materials
In addition, in order to obtain regular photonic crystal structure electrodes, the precision manufacturing instruments commonly used in laboratories are not only costly, but also cannot be mass-produced, which limits the wide application of photonic structure electrodes

Abstract

An electrode in a photonic crystal structure mixed with nano metal and a making method thereof belong to the technical field of solar batteries. The electrode comprises a substrate and a titanium dioxide film attached to the substrate. The titanium dioxide film contains surface hole arrays and is mixed with nano metal particles. The making method comprises the following steps: making colloid microspheres; making a positive photonic crystal template; making a rough film blank; making a titanium dioxide film of a structure carrying inverse opals; making a titanium dioxide film of photonic crystals, mixed with nano metal particles; making a film electrode in a photonic crystal structure mixed with nano metal for dye solar batteries. The making method has the advantages of cheap raw materials, easy raw material acquisition, simple technique, low cost and broad application range. The absorption spectrum of the electrode made is obviously broadened to the visible light area. The absorption peaks are enhanced, the reflected light strength is weakened, and the light absorption effect is improved.
