Description
Technical field
The invention belongs to DSSC technical field, and in particular to a kind of DSSC
Electrode structure, especially a kind of structure of large-area dye-sensitized solar battery electrode.
Background technology
DSSC, closed because its is simple in construction, cost is cheap and photoelectric transformation efficiency is higher
Note.The dye sensitization solar cell module of prior art generally comprises following major part：Light-sensitive coloring agent is adsorbed
The first electrode of nano porous semiconductor film and electrically conducting transparent bottom plate composition, in contrast and the containing Catalytic Layer that is spaced apart
The electrolyte and encapsulant filled between two electrodes, two electrodes.A transparency electrode is comprised at least in two electrodes to ensure
Absorption of the battery to light, it is electro-conductive glass or flexible and transparent conductive part usually using transparent conductivity bottom plate.Electrolyte
Organic solution usually containing iodine electricity pair.
At present, the transparent conductivity bottom plate of commercialization, tin-doped indium oxide (ITO) or fluorine doped tin oxide have generally been coated
Etc. (FTO) glass film plates of electrically conducting transparent part or other flexible clear materials, ITO or FTO layers have good corrosion resistance,
It can be prepared by sputtering method or chemical vapour deposition technique (CVD).But ITO or FTO resistivity is 10-4-10-3
Ω cm or so, it is 100 times or so of the metallic resistance rate such as silver, copper.Therefore, commercially available electrically conducting transparent substrate has higher electricity
Resistance, when for some electrooptical devices (such as DSSC), the particularly battery device of large area
When, photoelectric transformation efficiency declines obvious.It is contemplated that reduced by improving the thickness of transparency conducting layer (ITO or FTO etc.)
The resistance of electrically conducting transparent bottom plate.But the increase of conductive layer thickness can cause its absorptivity to light to increase, and can equally reduce too
The photoelectric transformation efficiency of positive energy battery.
In order to reduce the resistance of used by dye sensitization solar battery conductive soleplate, the method for generally use is in conduction at present
The gate electrode of high conductivity is set on bottom plate, and used material is generally silver.Such as Chinese invention patent
ZL200410014455.5 and ZL200410014456.X, it is by gate electrode that some monocells are separated, it is prepared for respectively
Large area internal series-connection and internal parallel battery.Same method is in ReproducibleManufacturingofDye-
SensitizedSolarCellsonaSemi-automatedBaseline(M.Deng Prog.Photovolt：
Res.Appl, 2003, volume 11,207-220 pages) also have been reported that.
The content of the invention
The present invention proposes a kind of new electrode structure, using the structure large-area dye-sensitized solar battery not only
The resistance of conductive soleplate is effectively reduced, and improves the effective area of battery, so as to more effectively improve this kind of light
The photoelectric conversion result of power conversion device.
To achieve the above object, the present invention adopts the following technical scheme that：
A kind of electrode structure of DSSC, including the visual bottom plate covered with conductive component, set on bottom plate
Semiconductor film or catalyst assembly with holes, the semiconductor film (such as titanium dioxide) with holes are impregnated with light-sensitive coloring agent, gone back on bottom plate
Highly conductive component is provided with, it is characterized in that, semiconductor film with holes or catalyst assembly are split blocking, block by the highly conductive component
It is connected with block, annularly.
Preferably：The semiconductor film with holes or catalyst assembly are blocking by highly conductive segmentation, in serpentine ring
Shape.
In order to avoid gate electrode contacts with each other and causes battery short circuit or by electrolytic corrosion, on the highly conductive component
Successively covered with insulation assembly, partition assembly.Or it is just coated with sealant on the highly conductive component.
It is as follows using the electrode structure of the present invention, the battery modular structure of preparation：
Between a kind of dye sensitization solar cell module, including first electrode, second electrode, first electrode and second electrode are relative
Every setting, peripheral sealing forms the cavity of closing, electrolyte is filled with the cavity, first electrode working region side is set
Semiconductor film with holes is put, the semiconductor film with holes is impregnated with light-sensitive coloring agent, and second electrode working region side sets catalyst
Component；It is characterized in that include highly conductive component in the first electrode and second electrode, by semiconductor film with holes or catalyst group
Part segmentation is blocking, and block connects with block, annularly；The closed cavity is interconnected.
Battery module of the present invention is subjected to connection in series-parallel, extensive series/parallel DSSC can be obtained.
Compared with prior art, the advantage of the invention is that：
1) under same air-proof condition, electrode structure of the invention improves the effective area of battery, can improve putting for battery
Electrical property.
2) battery module of electrode structure of the invention, electrolyte filling can be completed once, efficiently solve multiple lists
Battery irrigates the production efficiency problem that electrolyte is brought respectively.
