Abstract
The invention provides a novel semi-tempering process for back plate glass of thin-film solar cells. Tempering glass with brush lines smaller than or equal to 0.3mm/300mm in size and glass surface pressure stress controlled between 60MPa and 90MPa can be machined. Glass sheets are in tempering treatment after procedures of cutting, edging, drilling and cleaning, and are packaged into finished products after the assay is approved, and the tempering treatment sequentially includes heating treatment in a heating furnace, rapid cooling treatment in a rapid cooling furnace and slow cooling treatment in a secondary cooling furnace. The novel semi-tempering process is characterized in that the heating temperature in the heating furnace ranges from 660 DEG C to 720 DEG C, the speed of glass in a main furnace of the heating furnace is 120+/-20mm/s, and the furnace discharge speed is 650+/-50mm/s; and strengthened wind pressure ranges from 8820Pa to 10780Pa when the glass is rapidly cooled in the rapid cooling furnace.
Description
Technical field
The present invention relates to the processing technique field of thin-film solar cells, be specially a kind of half tempered technology of novel thin film used for solar batteries back-panel glass with glass.
Background technology
Back glass of thin film solar cells of mainly steel 3.2mm float glass, which compared with ordinary plate glass, while having the advantages of high strength, but it also poor flatness, striae, easy blew problem, and once it undermine the overall crushing, thus shortening the life of thin-film solar cells; while the semi-tempered float glass, tempered its flatness better than the whole, and its destruction is the source radial radial cracking along the crack, generally no tangential crack propagation, thus Currently there with a half tempered float glass float glass to replace the steel of the battery back glass as amorphous silicon, but the current wave of semi-tempered glass reinforcement requirements solely on the basis of their national standard ≤ 0.6mm/300mm (GB15763.2- 2005) or the European standard requirements ≤ 0.5? mm/300mm (EN12150-1-2000), semi-tempered glass surface compressive stress control 24Mpa ~ 60Mpa, the wave Zhu glass surface compressive stress requirements and still can not meet the high-quality thin-film solar cells Back glass wave Zhu ≤ 0.3? mm/300mm, glass surface compressive stress control 60Mpa ~ 90? Mpa between the requirements.
Summary of the invention
For the above problems, the present invention provides a novel thin-film solar cell back glass semi-steel process, which can be processed to meet the wave Zhu ≤ 0.3mm/300mm, the glass surface stress control 60Mpa ~ 90? Mpa between tempered glass.
Its technical scheme is such; Original sheet glass carries out tempering after cutting, edging, boring, cleaning handles; Packaging final prod after the assay was approved again; Said tempering processing comprises that successively the process furnace internal heating is handled, the interior Xu's deepfreeze that cool quickly is handled and the secondary cool furnace is interior of cool furnace fast, and it is characterized in that: the Heating temperature in the said process furnace is 660 ℃～720 ℃, and the speed of glass in the main stove of said process furnace is that 120 ± 20mm/s, the speed of coming out of the stove are 650 ± 50 mm/s; During cool quickly, the reinforcement blast is 8820pa～10780pa in said quick cool furnace.
It is further characterized in that: during cool quickly, top wind array pitch is from being 18 ± 5mm in said quick cool furnace, and bottom wind array pitch is from being 13 ± 5mm; When in said secondary cool furnace, carrying out Xu's deepfreeze, the Xu Leng blast is 1800 pa～2000pa, top wind array pitch from bottom wind array pitch from being 18 ± 5mm.
Process of the present invention for processing semi-tempered glass, which can satisfy the wave Zhu ≤ 0.3mm/300mm, and the glass surface compression stress control at 60Mpa ~ 90? Mpa requirements.
