Abstract
The present invention relates to a sealing method of a dye sensitization nanometer thin film solar cell. A polymer film or an adhesive is used as a sealing material. By preparation, cell box sealing and hole sealing, an electrolyte is sealed between a cell light anode and an anti electrode to make the dye sensitization nanometer thin film solar cell. The sealing method not only solves the sealing keys of large-area cells and assemblies thereof, but also realizes the manufacture of the large-area cells, and the present invention has the advantages of simple operation and low cost.
Description
Technical field
The present invention relates to a kind of encapsulating method of battery, exactly is a kind of encapsulating method of dye-sensitized nano film solar battery.
Background technology
The M.Gr tzel of the Institute of Technology such as Lausanne, SUI height in 1991 professor laboratory nature (O ' Regan, B.; Gr tzel.M, 1991,353,737) go up the achievement in research of a kind of brand-new dye-sensitized nano film solar battery of report, obtain extensive concern and attention in the world immediately.From 1991 was international research focus so far always.
Dye-sensitized nano film solar battery is that the compound system that utilizes the organic photosensitive functional molecular to combine with half semiconductor nano material carries out opto-electronic conversion to solar energy, it combines function and characteristics organic and inorganic photoelectric material: utilize the rapid electric charge of the collection optical property semi-conducting material of organic photosensitive dye efficient to shift and separate advantage, in conjunction with the porousness of semiconductor nano-crystal thin-film and high specific area, make full use of the flexibility of design of organic molecule and some new features that are different from the body material of nanometer semiconductor structure material.
Because the circumstance complication of the internal physical of dye-sensitized nano film solar battery and chemistry, electronics is accompanied by complicated course of reaction in the process transmission of electrolyte, these all can be had higher requirement to the solvent resistance of encapsulant, and want enough sealing intensities to prevent the volatilization and the leakage of electrolyte, this is the basic demand that reaches a long-life dye-sensitized nano film solar battery.
At present this battery at small size (less than 1cm
2) high conversion efficiency has reached about 11%, but area battery and assembly thereof owing to fail on the key issues such as cell sealing to solve, hinder the extensive use of this solar cell always.
Summary of the invention
The purpose of this invention is to provide a kind of sealing key that solves large-area solar cell and assembly, realize the encapsulating method of the dye-sensitized nano film solar battery that large-area solar cell is made.
A kind of encapsulating method of dye-sensitized nano film solar battery, it is with encapsulant electrolyte to be sealed between the light anode and counterelectrode of battery, it is characterized in that encapsulant adopts thin polymer film, makes through battery case sealing and sealing of hole.
The encapsulating method of described dye-sensitized nano film solar battery, it is characterized in that described sealing step is: (1), preparation, be that the polymeric seal film is tiled on metal or glass or other sheet material that can support, application machine, or the laser grooving and scribing technology is delineated into film the shape of required sealing film; (2), battery case sealing, be that the polymeric seal film that will have definite shape accurately is positioned to exert pressure with dull and stereotyped forcing press on the position of light anode and the required sealing of counterelectrode again, or heat, two interpolars are sealed fully; (3), sealing of hole, be that dye photoactivation agent and electrolyte are injected into by the aperture on the battery case in the battery case of sealing, with thin polymer film and thin glass sheet the aperture on the battery case is sealed again.
The preparation method of organic high molecular polymer film is:
Selection has thin polymer film such as the polyethylene and the poly-methyl-prop diluted acid film of certain sealing property, and application extruding, hot pressing, membrane technology are prepared into the film that thickness is 1～500 micron sealing with polymeric material.
Effect of the present invention
The present invention utilizes thin polymer film, through this method preparation, battery case sealing and sealing of hole for a long time, stably are sealed in electrolyte between the light anode and counterelectrode of battery, thereby solved the sealing key of area battery and assembly thereof, realized the making of area battery.The present invention is simple to operate again, and is with low cost.
Embodiment
Embodiment 1:
Choose the polyethylene of 100 micron thickness and the random copolymerization compound sealing film of poly-methyl-prop diluted acid, it is tiled on the sheet metal, use the sealing film that the laser grooving and scribing technology prepares definite shape.It is accurately positioned between light anode and the counterelectrode again, is heated to 100 ℃ under dull and stereotyped forcing press, heated sealant took out after 20 minutes, was the sealed cell box.Dye photoactivation agent and electrolyte are injected into by the aperture on the battery case in the battery case of sealing, the aperture on the battery case are sealed through heat seal with polymeric seal film and thin glass sheet again.
