Abstract
The invention discloses a preparation method of a photocathode of a sensitized solar cell on the basis of plastic underlay dyestuff. A pasty ethanol-based titanic oxide sizing agent with certain thickness is coated on the upper surface of a cleaned polyethylene glycol terephthalate (PET) plastic underlay plated with indium tin oxide (ITO) by a bistoury; after ethanol is completely vaporized; a layer of polyethylene plastic thin film is covered on the surface of dry titanic oxide powder; then the dry titanic oxide powder with the plastic underlay and the photocathode of the polyethylene plastic thin film are put into two parallel steel plates together; certain pressure is applied to the steel plates by certain speed; after the pressure is stable, the photocathode is taken out from the steel plates and titanic oxide nano thin film is deposed on the plastic underlay, thereby obtaining the photocathode of the sensitized solar cell of the soft dyestuff on the plastic underlay. The preparation method has low cost and simple technique and is easy for being repeated.
Description
Technical field
The present invention relates to a kind of preparation method based on plastic dye-sensitized solar cells light anode.
Background technology
Dye-sensitized solar cells is subjected to domestic and international broad research at present because of its high efficiency (～11%) low cost.Particularly use the flexible dye-sensitized solar cell of the conductive plastic film making of flexible and light weight,, and especially cause concern because of its potential commercial application value.Yet the problem of the key of dye-sensitized solar cells that the plastic film substrate is made is that plastic can not be born high temperature up to 450-450 ℃ and low than the dye-sensitized solar cells efficient of making of Conducting Glass.At present, the film that low temperature prepares titanium dioxide nanostructure there are some researches show the method that has adopted a kind of thermal spraying, has obtained about 5% efficient under 0.1 sun, but dye-sensitized solar cells efficient drops to 3% under 1 sun; In addition, also there is the scholar to invent a kind of method of Tear Film, by at first on gold, coating the layer of titanium dioxide nano structure membrane then at deposition one deck gold on the glass substrate, behind high temperature sintering, after gold dissolved in containing the corrosive liquid of iodine, the titanium deoxid film behind the high temperature sintering transferred on the conductive plastics substrate and obtained the battery of 4.8% efficient, but still there is complex process in this battery, cost is higher, is difficult to realize commercialization.
Summary of the invention
The object of the present invention is to provide a kind of titanium dioxide nanostructure film to be deposited on the preparation method of flexible dye-sensitized solar cell light anode on plastic by certain pressure.
Concrete steps are:
(1) after PETG (PET) plastic film that will be coated with indium tin oxide (ITO) cleans with acetone, standby only with washed with de-ionized water then;
(2) the commercialization nano TiO 2 powder is put into the ethanol the inside of spectroscopic pure level, stirs device with magnetic force and stirred 2-3 hour, make the ethanol based percentage by weight and be the pasty slurry of 20% nano TiO 2 powder;
(3) the ethanol based slurry that step (2) is made is applied in the middle of the parallel magic adhesive tape of 20-50 micron thickness, and wherein parallel magic adhesive tape is attached on the plastic of step (1), spreads upon thickness on the plastic with the control slurry;
(4) use the scalpel knifing, be evenly coated on the plastic until titania slurry;
(5) treat after the ethanol based titania slurry nature evaporate to dryness, at the good titanium dioxide dry powder film loam cake last layer sealed polyethylene plastic of drying, to make things convenient for the lamination rear demoulding;
(6) with the described sealed polyethylene plastic of step (5), the light anode of titanium dioxide dry powder film and plastic is put between the parallel steel plate, according to the pressure-speed of 150 kg/cm/seconds, steel plate is applied the pressure of 200-400 kg/cm; Treat pressure stability, after static pressure 5-10 minute, the light anode is taken out from parallel steel plate, promptly obtain on plastic, to scribble the light anode of titanium dioxide nanostructure film.
The present invention has obtained to be higher than 5% efficient by adopt a kind of method of compressing the titanium dioxide nanostructure film on plastic, and cost of the present invention is low, technology is simple, is easy to repetition, to realizing that from now on making flexible dye-sensitized battery has great importance.
