Existing DSSC generally adopts negative electrode and light anode to be oppositely arranged, be full of electrolyte between the two, the solar cell of this structure, light anode and electrolytical contact area little, cause the photoelectric conversion rate of the solar cell of this type very low.
Summary of the invention
For solving the low problem of existing DSSC optoelectronic transformation efficiency, the invention provides a kind of two net superposition DSSC, by the improvement to light Anode and battery structure, considerably increase light anode and electrolytical contact area, thus increase substantially photoelectric conversion rate.
The present invention is the technical scheme solving the problems of the technologies described above employing: a kind of two net superposition DSSC, comprises the I in cavity, light anode and cavity
-/ I
3-type electrolyte, described cavity is the cavity that electro-conductive glass surrounds, the two ends of this cavity are sealed by diaphragm seal, light anode is arranged on the center of cavity, described smooth anode is that double-deck netted folded structures forms, and two-layer network structure be relatively rotate be greater than 0 °, be less than the angle of 180 ° after superposition, on light anode growth have titania nanotube layer, titania nanotube layer is adsorbed with sensitizing dyestuff.
The conducting surface of described electro-conductive glass is coated with metal platinum layer, silver coating or aluminium lamination on the nonconductive surface of non-sunlight incidence end electro-conductive glass.
The mesh form of described cancellated smooth anode is rhombus, and two-layer network structure superposes formation light anode after relatively rotating 90 °.
The material of described smooth anode is industrially pure titanium, zinc or brass.
In the present invention, the titania nanotube layer that light anode grows can be obtained by Ni―Ti anode oxidation.
Sensitizing dyestuff of the present invention respectively can use a kind of sensitizing dyestuff by every layer of net, also can be every layer on the net with two kinds of sensitizing dyestufves, sensitizing dyestuff is not of the same race mainly in order to respond the visible ray of different wave length, expansion photoresponse scope, sensitizing dyestuff has N719, N3, GD3, Z907 etc. can for selecting.
In the present invention, plating platinum layer on the conducting surface of electro-conductive glass, on the nonconductive surface of non-sunlight incidence end electro-conductive glass, silver coating or aluminium lamination do mirror process, its object has two: one, utilizes the catalytic action of platinum, increases the transmission rate of electronics, thus raising photoelectric conversion efficiency, its two, will to inject in battery but by the light that reflects by being again irradiated on light anode after electro-conductive glass minute surface secondary reflection, thus improve the utilance of light.
Beneficial effect: the present invention compared with prior art has the following advantages:
1) using electro-conductive glass as negative electrode, and light anode is positioned in the cavity of electro-conductive glass formation, the surface area so not only making light anode relative with negative electrode increases, thus increase the surface area accepting illumination, and can will to inject in battery but by the light that reflects by being again irradiated on light anode after electro-conductive glass minute surface secondary reflection, thus improve the utilance of light;
2) by light anode is set to double-deck network structure, increase the surface area of the titania nanotube layer of growth on it, thus all increase with electrolytical contact area and the amount of adsorbing sensitizing dyestuff, and then increase substantially photoelectric conversion efficiency.
