[0027] The installation groove 202 is arranged on the left and right sides of the connecting support 201, two groups of photovoltaic tile assemblies 1 are connected to each other through the connecting support 201, the installation groove 202 is provided with sealing silica gel 205 at the connection position of the photovoltaic tile assembly 1, the two groups of connecting supports 201 are clamped to each other through the positioning clamping block 203 and the positioning clamping groove 204, and the positioning clamping block 203 and the positioning clamping groove 204 are matched in size, the photovoltaic tile assembly 1 is arranged in a wave shape through the connecting assembly 2, and the upper photovoltaic tile assembly 1 covers the lower photovoltaic tile assembly 1.

[0028] Through the above technical scheme, when the photovoltaic tile assemblies 1 are connected, they are placed in an alternating manner, the front and rear rows of photovoltaic tile assemblies 1 are installed on the same connecting support 201 through the installation groove 202, and the connection position is sealed through the sealing silica gel 205, so that water is prevented from entering the joint, and at the same time, since the edge of the upper photovoltaic tile assembly 1 exceeds the lower photovoltaic tile assembly 1, the rainwater on the upper photovoltaic tile assembly 1 can be guided out through the surface of the lower photovoltaic tile assembly 1, which provides a good waterproof effect and convenient connection for the photovoltaic tile assembly 1.

[0029] Specifically, as shown in Figure 1 and Figure 4 The photovoltaic tile assembly 1 comprises, from top to bottom, a top curved tempered glass 101, a cell layer 102 and a bottom curved tempered glass 103, and a curing glue layer 104 is arranged between the top curved tempered glass 101, the cell layer 102 and the bottom curved tempered glass 103, the curing glue layer 104 is a rosin light curing glue layer, the cell layer 102 comprises cell pieces 10201 and a bus bar 10202 arranged on one side of the cell pieces 10201, and the gap around each group of cell pieces 10201 is 2 cm.

[0030] Through the above technical scheme, the rosin-based adhesive used in the rosin light curing glue layer is prepared by the following method:

[0031] Synthesis of polymerizable rosin monomer: 10 mmol of dehydroabietic acid DA is reacted with 20 mmol of oxalyl chloride in dichloromethane at 25°C for 4 h, and after the reaction is completed, the solvent and unreacted oxalyl chloride are removed by a rotary evaporator to obtain dehydroabietic acid chloride DA-Cl; then the obtained dehydroabietic acid chloride is dissolved in 10 mL of DMF, and then 0.3 g of PETA, 10 mmol of DMAP and 20 mL of DMF are added dropwise into the reactor, heated to 45°C and reacted for 7 h. After the reaction is completed, the supernatant is separated by centrifugation. Wash with anhydrous ethanol until colorless, completely remove the unreacted rosin chloride, and finally wash with n-hexane and dry at 40°C under vacuum until the mass is constant, to obtain the branched rosin crosslinking agent rosin-based pentaerythritol triacrylate, DAPETA;

[0032] Preparation of rosin-based adhesive: 1 g of tetrahydrofurfuryl methacrylate, 9 g of lauryl methacrylate, 0.5 g of DAPETA and 0.5 g of 11735 wt% were mixed and added to a round-bottom flask with stirring device, after purging with nitrogen to remove oxygen, the monomer was initiated to polymerize by irradiating from the lower part of the round-bottom flask with a UV LED light source with a wavelength of 365 nm and an intensity of 2 mW / cm2, the distance between the UV LED light source and the bottom of the flask was fixed at 10 cm, and the conversion rate and viscosity of the reaction system were determined in a timely manner during the polymerization process. The light irradiation time was about 15 minutes, and the prepared adhesive had a viscosity of about 960 mPa.s and a conversion rate of about 61.2%.

[0033] Since rosin is a natural resin secreted by pine trees, which is distilled to produce a product, its main structure is various resin acids with a hydrogenophenyl ring structure, and its unique structure gives rosin certain ultraviolet light absorption ability, which has the potential to produce ultraviolet light absorbing materials. At the same time, the carboxyl group on the molecule has a certain reactivity, which provides a modification site for the reaction, so the rosin-based adhesive can well replace the existing photovoltaic tile adhesive used in the existing photovoltaic tile, and a certain amount of rosin-based adhesive is applied on the bottom curved tempered glass 103, and the cell sheet 10201 is placed on the rosin-based adhesive. The cell sheet 10201 can use flexible BC cell sheet to ensure its transparency and flexibility, and can also use flexible cell sheet, and the thickness of the cell sheet is below 60µm to ensure its transparency and flexibility. The flexible BC cell sheet needs to be welded with the bus bar 10202, and a certain amount of rosin-based adhesive is applied on the cell sheet layer 102. Cover with top curved tempered glass 101, put in ultraviolet light curing machine for curing, then use mechanical arm to hold photovoltaic tile assembly 1, slowly turn it over, and use light curing lamp to cure the back again, so that it is fully cured. The light intensity during the curing process is about 80 mW / cm2, and the distance between the edges should be at least 2 cm when laying the cell sheet, and the amount of adhesive should not be too small. Before curing, the rosin-based adhesive should fill the gap between the two glass plates, so that the two glass plates can be completely fixed after the first curing, and the amount of rosin-based adhesive should not be too much to minimize the pollution of the adhesive to the production environment. A cheap disposable plastic film can be placed under the glass plate to avoid contamination of the adhesive to the production equipment.

[0034] Working principle: When the photovoltaic tile assembly 1 is connected, it is placed in an alternating manner, and the front and rear rows of photovoltaic tile assemblies 1 are installed on the same group of connecting brackets 201 through the installation groove 202, and are sealed at the connection through the sealing silicone 205 to avoid water entering the joint. At the same time, since the edge of the upper photovoltaic tile assembly 1 exceeds the lower photovoltaic tile assembly 1, the rainwater on the upper photovoltaic tile assembly 1 can be guided out through the surface of the lower photovoltaic tile assembly 1, providing good waterproof effect and convenient connection for the photovoltaic tile assembly 1.

[0035] Finally, it should be noted that: the above embodiments are used to illustrate the technical solutions of the present application, but not limited to them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement to part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
