Description
Technical field
The present invention relates to a kind of novel sun of the preparation field of solar cell more particularly to photoconductive tube interpenetrating intraoral illumination electricity
Pond and preparation method and content.
Background technique
Solar cell is many kinds of, mainly imitation photosynthesis principle, wherein the film preparation of solar cell to close weight
It wants.The preparation of film promotes solar battery with more inexpensive, and plant can be carried out photosynthesis using the sun in simulation nature,
It converts solar energy into electrical energy.
Photoelectric conversion process in solar cell is complex, and determines that there are many factor of its incident photon-to-electron conversion efficiency, wherein
The selection of anode film is a vital part.The research of early stage in this respect is concentrated mainly on plate electrode, this kind of
The major defect of electrode is can only be in electrode surface absorption monolayer dye molecule, due to the effect of monolayer of dye molecule absorption sunlight
Rate is very low, and photoelectric conversion efficiency is unable to get always raising.The shortcomings that in order to overcome monolayer of dye, has introduced nanometer later
Porous titanium dioxide film conductive film, so that entire semiconductor film has very big interior surface area, can absorb more as sponge
More dyestuff monolayers, monolayer can only be adsorbed in original battery and absorb lacking for a small amount of sunlight by overcoming in this way
Point, and sunlight multiple reflections in film can be made, it absorbs sunlight repeatedly, can produce bigger photoelectric current.
Although sunray is irradiated on porous film, photoelectric conversion efficiency is improved, due to dyestuff and one
A little electrolyte etc. are to the strong absorption of sunlight, so that sun light intensity exponentially decays, and the porous membrane of script has one
Fixed thickness, so sunlight is difficult to be irradiated to the end of film.Currently existing scheme is to increase by one layer greatly in film surface rear end
Particle reflecting layer, but this layer of emission layer is that the light that will decay turns back to film.The light intensity of fold-back is weaker, while by
Maximum absorption spectrum is absorbed totally in leading portion, remaining is the weaker longer wavelengths of feux rouges of some absorptions, and is not up to
The sunlight for the full spectrum that our novel thin films of the invention are transmitted；In addition, since traditional solar cell encapsulates electrolyte
Needs, reserve the blank parts other than film often in order to encapsulate electrolyte, and the area of this part does not have always
It is utilized, wastes sizable space.
Summary of the invention
It is an object of the present invention to provide a kind of novel solar cells of photoconductive tube interpenetrating intraoral illumination, by changing photo-anode film
Structure, to increase the quantity of illumination of photo-anode film, to improve the incident photon-to-electron conversion efficiency of solar cell.It will be in light anode substrate
The blank area part lost of part of non-photo-anode film adequately utilize, and sunlight is introduced by photoconductive tube
In photo-anode film, and then allow photo-anode film that can receive more sunlight irradiations.
The invention is realized in this way a kind of novel solar cell of photoconductive tube interpenetrating intraoral illumination, mainly by light anode base
Bottom, photocathode substrate, electrolyte composition；It is characterized by: blank place will by photoconductive tube in substrate where photo-anode film
The sunlight for not being irradiated to film is introduced into photo-anode film；Wherein, sunlight light is not irradiated by optical fiber in recycling
Sunlight on to anode film, sunlight are being received by entering a nanometer scattering tube after being totally reflected in the nano optical fibers of both ends
Mie scattering pipe is entered in photo-anode film by the scattering of light, constitutes light anode substrate with anode film；And with photocathode base
Bottom and electrolyte together form solar cell.
In light anode substrate a nanometer light then can be connected in the blank parts of non-semiconductor film with applying semiconducting film
Fibre, is inserted into nanometer scattering tube in semiconductive thin film, and the both ends of nanometer scattering tube and the nano optical fibers that are connected in blank parts
The other end is connected, to constitute photoconductive tube interpenetrating intraoral illumination film with anode semiconductive thin film.
A kind of novel solar cell of photoconductive tube interpenetrating intraoral illumination, is introduced primarily into photoconductive tube structure, passes through the nanometer at both ends
Optical fiber and intermediate nano-vacuum-tubes sunlight is entered after the total reflection in optical fiber in nanometer scattering tube scatter to it is thin
In film.
It is combined on photo-anode substrate by several groups photoconductive tube with photo-anode film, makes the non-photo-anode film of light anode
The sunlight of blank parts makes full use of, and is introduced into inside film by photoconductive tube, constitutes photoconductive tube interpenetrating intraoral illumination
Novel photo-anode film.
The novel photo-anode film for the photoconductive tube interpenetrating intraoral illumination being made of this photoconductive tube is formed by light anode substrate,
Solar cell can be constituted with its photocathode substrate and electrolyte.Since the sunlight of light anode substrate non-semiconductor film portion draws
Enter onto photo-anode film, scatter sunlight in film, to generate bigger photoelectric current, improves photoelectric conversion efficiency.
The present invention has the advantages that (1) by using both ends nanometer light compared with existing laboratory test technology
Fibre is entered into intermediate nanometer scattering tube after sun light total reflection, scatters to photo-anode by light in nanometer scattering tube
In film, the mode of traditional sunlight irradiation photo-anode film is had successfulLY changed.(2) photoconductive tube has been used to construct photoconductive tube interpenetrating
The photo-anode film of film lighting film, the script for being receives light mode.(3) it can solve the one way propagation of sunlight and cannot pass
The drawbacks of to the end of film, introduce photoconductive tube interpenetrating film lighting film can make solar irradiation to script solar irradiation not
The end of the film arrived, and the full spectrum of sunlight is introduced into film, so that its solar irradiation is mapped to the end of film.(4) lead to
It crosses photoconductive tube and constructs photoconductive tube interpenetrating film lighting film and can be used for the solar cell of multiclass, solve photoelectric conversion efficiency
The problem of being difficult to improve.
