Abstract
A packaging structure for a thin-film solar battery solves the technical problem of high fragment rate caused by the reason that to-be-packaged glass is subjected to non-uniform stress in the packaging process under the influence of a lead-out conductive wire on a back electrode layer, as well as a bus bar and a drainage bar. The adopted technical scheme is that the packaging structure comprises a solar battery photovoltaic absorbing layer, a substrate baseplate of the back electrode layer, an insulating film and a packaging back panel, wherein the structural layer of the packaging back panel comprises a first back panel positioned on the upper surface of the back electrode layer of the substrate baseplate through the insulating film, and a second back panel positioned on the upper surface of the first back panel through a buffer layer. The key point of the utility model is that the double-layered packaging back panel replaces single-layered back panel glass in the prior art, so that the fragment rate during packaging of solar battery components is lowered under the premise that the packaging equipment is unchanged, the packaging yield of the solar battery components is increased from 93%-95% to 99.99%, meanwhile, the production efficiency is improved, and the production cost is saved for manufacturers.
Description
Technical field
The utility model belongs to field of thin film solar cells, relates to a kind of encapsulating structure of thin-film solar cells, particularly a kind of encapsulating structure that encapsulates the thin-film solar cells of quality percentage by improved encapsulation backboard, raising.
Background technology
Along with the mankind's continuous development, energy resource consumption is increasing, and the total amount of traditional energy is in continuous minimizing.Solar energy most possibly substitutes traditional energy, and when solar module encapsulated, product encapsulation quality percentage had directly influenced the production cost of enterprise.
Make the field at solar cell, the technological process of using glass back plate to encapsulate is: close sheet, lamination, dress terminal box, packing is dispatched from the factory.The processing procedure of wherein closing sheet and lamination is: will have photovoltaic absorbed layer and dorsum electrode layer underlay substrate glass, close sheet and form solar module closing the sheet chamber by insulation film and encapsulation backboard; Then solar module is sent into roll squeezer or laminating machine carries out pre-packaged to assembly; Because the dorsum electrode layer of underlay substrate is provided with busbar, the drainage strip of each sub-battery and is connected to form the monoblock solar cell, therefore can form rough encapsulating face at the dorsum electrode layer upper surface.When the silica gel plate of exerting pressure of roll squeezer was exerted pressure on package assembling, rough encapsulating face can cause encapsulation backboard unbalance stress, and encapsulate on the backboard and blind crack can occur, as easy as rolling off a log fragmentation this moment.If get into autoclave afterwards again; Through vacuumize, heating and pressurizing; After the decrease temperature and pressure series of temperature acute variation; Very large crackle will occur on the back-panel glass of the solar module that obtains, finally cause solar module fragmentation rate, and the waste production cost influences production efficiency again up to more than 5%.
Summary of the invention
The utility model will solve packaged glass and influenced by draw lead and busbar and drainage strip on the dorsum electrode layer; Discontinuity causes the high technical problem of fragmentation rate in encapsulation process; A kind of encapsulating structure of improved thin film solar is provided, has replaced individual layer back-panel glass of the prior art, reduced solar module encapsulation fragmentation rate through adopting double-deck encapsulation backboard; Improved production efficiency, also practiced thrift production cost for manufacturer.
The utility model for realizing the technical scheme that goal of the invention adopts is; A kind of encapsulating structure of thin-film solar cells; Comprise the underlay substrate that has solar cell photovoltaic absorbed layer and dorsum electrode layer, insulation film and encapsulation backboard, comprise in the structure sheaf of above-mentioned encapsulation backboard: second backboard that is positioned at first backboard of underlay substrate dorsum electrode layer upper surface and is positioned at the first backboard upper surface by resilient coating by the insulation film.
The key of the utility model is to adopt double-deck encapsulation backboard to replace individual layer back-panel glass of the prior art; Under the prerequisite that does not change sealed in unit; Reduced solar module encapsulation fragmentation rate; Make the encapsulation yields of solar module be increased to 99.99%, improved production efficiency simultaneously, also practiced thrift production cost for manufacturer by 93%～95%.
