The invention is realized by the following technical scheme:
the invention provides a film photovoltaic tile, which is a quadrilateral tile and comprises a film photovoltaic tile main body 1, a water guide purline 2 and a mounting hanging beam 3, wherein the water guide purline 2 and the mounting hanging beam are fixed together with the film photovoltaic tile main body 1;
the thin film photovoltaic tile body 1 comprises from top to bottom in sequence: the solar photovoltaic power generation device comprises front tempered glass 11, an adhesive film 12, a sealing strip layer 13, a thin film photovoltaic power generation layer 14 and back plate glass 15;
one side of the film photovoltaic tile main body 1 is provided with the water guide purline 2;
and the mounting hanging beam 3 is arranged on one side edge adjacent to the water guide purline 2, and the rain-proof adhesive tape 4 is arranged on the film photovoltaic tile main body 1 and the mounting hanging beam 3.
The quadrilateral tile can be a rectangle, a square or a parallelogram, and is certainly not limited to the three shapes, and other shapes can be designed for convenience in installation and attractiveness.
The front plate toughened glass 11 is super-white transparent toughened glass plated with an anti-reflection film, and the back plate glass is also transparent. The antireflection film coated on the front tempered glass 11 is used for absorbing more sunlight irradiated on the glass and not reflecting the sunlight back, and the ultra-white transparent glass is used for transmitting more sunlight into the power generation layer to generate more electricity. In addition, because the front plate toughened glass 11 and the back plate glass 15 are transparent, the photovoltaic flat tile can show different colors to match the architectural design effect by replacing the adhesive films with different colors.
Preferably, the mounting hanging beam 3 has a mounting hole 31 below, which is fixedly connected with a mounting nail 32 on the roof to mount the thin film photovoltaic tile on the roof.
Preferably, the mounting holes 31 are uniformly distributed below the mounting hanging beam 3 and correspond to the positions and the number of the mounting nails 32 on the roof.
Preferably, the water guide purlin 2 comprises two parts, one part is an installation part 21 located below the back plate glass 15 of the film photovoltaic tile main body 1, and the other part is a water guide part 22 extending out of the film photovoltaic tile main body 1.
Preferably, the mounting portion 21 has a three-dimensional cylindrical structure, and the water guide portion 22 has a circular arc cylindrical structure.
Preferably, the water guide part 22 further has a water guide platform 23 thereon.
Preferably, two adjacent thin film photovoltaic tiles are overlapped through the water guide portion 22, the opposite side back plate glass 15 of one of the thin film photovoltaic tiles, which is provided with the water guide purlin 2, is overlapped on the water guide portion 22 extending outwards of the other adjacent thin film photovoltaic tile, and a water guide groove 24 is formed between the back plate glass 15 and the water guide platform 23 on the water guide portion 22. This allows rainwater, even if it leaks through the gap between the two, to exit the roof along the gutter 24.
In a second aspect, the present invention provides a method for preparing a thin film photovoltaic tile according to the first aspect of the present invention, comprising the steps of:
1) selecting back plate glass 15 with the surface coated with a thin film photovoltaic chip, wherein the thin film photovoltaic chip is a thin film photovoltaic power generation layer 14, and cutting the back plate glass into the required design size of a thin film photovoltaic tile;
2) taking the cut back plate glass 15 plated with the thin film photovoltaic chip, carrying out primary edge cleaning on the periphery of the thin film photovoltaic chip by using a laser edge cleaner, cleaning a power generation film layer and a back electrode conducting layer molybdenum layer on the periphery of the thin film photovoltaic chip, wherein the primary edge cleaning area is used for edge sealing, butyl rubber is used for edge sealing, and the width of the edge sealing is 8-10 mm;
3) secondly, performing secondary edge cleaning on the thin film photovoltaic chip subjected to the primary edge cleaning, performing secondary edge cleaning on the edge of the thin film photovoltaic chip with the primary edge cleaning area, only cleaning a power generation film layer at the time, and leaving a back electrode conducting layer molybdenum layer, wherein the back electrode conducting layer molybdenum layer on the secondary edge cleaning area is used for pasting a bus bar in a subsequent process;
4) attaching a bus bar on the molybdenum layer of the back electrode conducting layer on the secondary edge cleaning area, wherein the bus bar is used for leading out electric energy generated by the thin film photovoltaic chip;
5) butyl rubber is arranged in the first edge cleaning area for waterproof sealing, and the butyl rubber forms a sealing strip layer 13;
6) laminating, namely aligning a front tempered glass 11 and a back glass 15 with a sealing strip layer 13 and a thin film photovoltaic power generation layer 14, and adding an adhesive film 12 into the middle of the front tempered glass and the back glass, and sending the front tempered glass and the back glass into the next laminating process;
7) mounting a junction box after lamination to form a film photovoltaic tile main body, and punching two bus bar leading-out holes in advance at the designed junction box position;
8) sequentially using weather-proof structural adhesive, and installing a rainwater-proof adhesive tape 4, a hanging beam 3 and a water guide purline 2 on the side edge of the main body of the film photovoltaic tile according to the design;
9) and (5) standing for more than 24 hours until the weather-resistant structural adhesive is solidified to obtain the film photovoltaic tile.
Preferably, in step 2, the width of the first edge deletion area around the thin film photovoltaic chip is 8-10mm, and preferably 9 mm.
Preferably, in step 3, the width of the peripheral second edge deletion area of the thin film photovoltaic chip is 5-8mm, preferably 5 mm, and the width is determined according to the width of the bus bar.
In the actual production process, the prepared film photovoltaic tile needs to be subjected to a classifying and packaging step after electrical property detection is qualified.
The thin film photovoltaic chip used in the invention is directly plated on the back plate glass 15 at the beginning, and the shape of the thin film photovoltaic chip is processed and packaged together with the back plate glass 15 and other elements. It is of course also possible to choose the backsheet glass 15 and then first coat its surface with the thin-film photovoltaic chips.
The different purposes of twice edge cleaning are that the first edge cleaning is to clean the power generation film layer and the back electrode conducting layer molybdenum layer and is used for edge sealing; and the secondary edge cleaning is to further clean the power generation film layer on the basis of the edge of the primary edge cleaning, and the back electrode conducting layer molybdenum layer is left to be used for adhering the bus bar for conducting. Because the plating power generation layer is irregular on the upper edge part of the backboard glass, and the edge part needs to be removed by 8-10mm because the edge sealing part can not be provided with the power generation layer. The secondary edge cleaning is to clean the power generation layer and the molybdenum layer of the back electrode, and the secondary edge cleaning is to clean the power generation film layer on the most marginal photovoltaic power generation unit (the power generation coating can be divided into a plurality of single power generation units according to the power generation voltage and the electrical property, the power generation units are connected in series to obtain higher voltage) after one layer of edge cleaning, so as to leave the molybdenum layer, (the secondary edge cleaning only cleans the power generation layer, and the molybdenum layer is reserved for conducting electricity).
