Silk light anode integrated efficient electronic collection dye sensitized solar battery

Abstract

The invention discloses a dye sensitized solar battery integrated by a threadlike light anode for efficiently collecting electrons, the solar battery is composed of three layers of structures, wherein the first layer is a super-white glass for packaging a cover board, the second layer is a plurality of coating metallic wires of the light anode which are interconnected in parallel, the coating metallic wires are the metallic wires which resist the corrosion of electrolyte or bandwidth gap nanometer crystal semiconductor oxide thin film that a conducting fiber is coated through coating procedure as charge separation effect; after heat treatment, the sensitized dye is adsorbed to prepare the second layer; the third layer is a coating metal sheet as pair electrodes; the gap between the super-white glass and the coating metal sheet is packaged to form a sealed space which is replete with the electrolyte having the redox. The solar battery of the invention can efficiently collect the electrons and adsorbs more dye to further improve the light absorption of the light anode, solving the problems of large resistance of the conduction glass substrate which limits the battery efficiency, of preparation in large area and of serial, parallel connections of the assemblies, and further enhancing the efficiency of battery.

Description

technical field

[0001] The invention relates to the field of photovoltaic utilization of solar energy, in particular to a solar cell. Background technique

[0002] Dye-sensitized solar cells have become a hotspot of scientific research because of their simple fabrication process and extremely low cost. One of the reasons why dye-sensitized solar cells cannot be industrialized in the short term is that the efficiency is still low. In thin-film solar cells, it is still unable to compete with mature solar cells such as amorphous silicon and CIGS. key to industrialization.

[0003] Traditional dye-sensitized solar cells adopt a sandwich structure with conductive glass as the substrate, see Figure 1. On one side of transparent conductive glass 1 (TCO), a layer of porous nanocrystalline oxide film (usually TiO 2 ), after heat treatment, the single-layer dye 2 is adsorbed to form a photoanode, and the counter electrode is made of a transparent conductive glass 3 coated with cata...
