The utility model has the characteristics that the battery component sequentially consists of a glass substrate (1), a transparent electroplated layer (2), an A-Si layer (3), an aluminum film back-piece electrode layer (4) and an adhesive layer (5); and the peripheries of the A-Si layer (3), the aluminum film back-piece electrode layer (4) and the adhesive layer (5) are sealed by a sealing adhesive layer I (6) and a sealing adhesive layer II (7) to form the A-Si battery component. With the adoption of a double-sealing way, a solar film battery is effectively protected from being corroded by outside steam, dust and the like.
Description
Technical field
The utility model relates to a kind of novel amorphous silicon battery assembly, belongs to field of semiconductor devices.
Background technology
Along with Chinese economic development, the raising of living standards of the people and quality, with energy crisis and environmental problem highlights the development of national governments and various circles of society's pay attention to day by day new forms of energy simultaneously.The extensive use of solar energy power generating has embodied the theory of the sustainable development energy and recycling economy, will readjust the energy structure, and ensures energy security, is improving and the environment and guarantee to occupy the status that becomes more and more important in the sustainable development of human society of preserving our planet.China's photovoltaic industry has been caught historical opportunity to develop, continues to optimize production technology, improves management system, improves production quality, the existing in the world higher competitiveness of product.This developing into of strategic industry with ecological significance, Significance for Environment, social effect of photovoltaic new forms of energy is built environmental society, realization sustainable development, is making increasing contribution.
Solar energy photovoltaic panel mainly is divided into two classes: monocrystalline/polycrystalline silicon and amorphous silicon thin-film solar cell.Make comparisons with monocrystalline/polycrystalline silicon and amorphous silicon thin-film solar cell, at first on conversion usefulness, polysilicon is in response to the unmodifiable physical characteristic of silicon, and it is the most high-effect to be 15% to 16%; Amorphous silicon membrane can be by precipitation different chemical characteristic material in different section layers, will change usefulness and be promoted to 12% or higher, in theory Gao Gengkeda 17.8% by 6%.Secondly, the sunlight wavelength that film absorption is wider, running is also preferable under cloudy day or faint sunlight; On the contrary, the usefulness of polysilicon will descend under darker situation rapidly, so the conversion efficiency ratio polysilicon of amorphous silicon membrane under actual environment exceeds more than 10%.Moreover though the conversion usefulness of amorphous silicon membrane only reaches polysilicon half, therefore production cost, has increasing amorphous silicon thin-film solar cell to capture the more market space far below polysilicon.
Though amorphous silicon thin-film solar cell has above-mentioned advantage, but because the characteristics of production technology own, different with monocrystalline/polycrystalline silicon, make solar module and do not use the frame encapsulation technology, solar panel is directly exposed in the air, materials such as in use airborne moisture, dust can slowly be penetrated in the cell panel, gradually cell panel are carried out corrosion failure.At present, the manufacturer of part solar film battery assembly has adopted the method for butyl rubber fluid sealant (polyisobutene and polyisoprene are the PUR that main body cooperates inorganic filler) sealing to stop airborne moisture to infiltrate, though the butyl rubber moisture permeability is low, infiltration has the excellent prevention effect for aqueous vapor, but because butyl sealant is to the bad adhesion between two blocks of glass, clashed at solar battery sheet, in the process of vibration, the circulation of outdoor high low temperature and ultraviolet irradiation, be easy to lose caking property, thereby lose safeguard function.
Summary of the invention
The purpose of this utility model is to provide a kind of novel amorphous silicon battery assembly at the deficiencies in the prior art.Be characterized in making on the basis of original technology, adopt the encapsulating method of two seals glue, adopt butyl sealant, the infiltration of stopping aqueous vapor near the solar panel direction at amorphous silicon; Outer other organic class fluid sealant that adopts bonds together two blocks of glass of solar film battery well, has played the effect of structure, thereby fundamentally stops the infiltration of moisture or other impurity in use of solar film battery plate.
The purpose of this utility model is realized by following technical measures.
Novel amorphous silicon battery assembly is connected with tack coat by substrate of glass, transparent electrodeposited coating, amorphous silicon layer, aluminium film tergite utmost point layer successively, constitutes the amorphous silicon battery assembly with sealant layer one and sealant layer two sealings around amorphous silicon layer, aluminium film tergite utmost point layer and the tack coat.
Amorphous silicon layer is the amorphous silicon layer of doped with boron atom and Doping Phosphorus atom.
Aluminium film tergite utmost point layer is the alloy-layer of aluminium lamination or aluminium and silver.
Tack coat is ethylene-vinyl acetate copolymer layer (EVA) or polyvinyl butyral resin layer (PVB).
Sealant layer one is for polyisobutene and polyisoprene being the PUR of main body cooperation inorganic filler.
Sealant layer two is a kind of in the close glue of organosilicon, ethylene-vinyl acetate copolymer (EVA) fluid sealant, polyvinyl chloride (PVC) fluid sealant, polyolefin copolymer, polyamide fluid sealant, polyurethane sealant or the polysulfide sealant.
The utlity model has following advantage:
1. solar module adopts the two seals mode; the effect of structure is played in sealing together; two battery sheets are bondd well, and the effect that prevents the aqueous vapor infiltration is played in the sealing of two roads, thereby has protected solar film battery to be difficult for by the erosion of materials such as extraneous aqueous vapor and dust effectively.
2. technology is simple, helps industrial production and processing.
