Method for manufacturing color photovoltaic device by using water-soluble film and color photovoltaic device

Abstract

The invention belongs to the technical field of color photovoltaic manufacturing, and particularly relates to a method for manufacturing a color photovoltaic by using a water-soluble film and the color photovoltaic. The method for manufacturing the colored photovoltaic by using the water-soluble film is applied to colored printing of the colored photovoltaic in an irregular shape, and comprises the following steps of: printing a pre-printed pattern on the water-soluble film by using a water-soluble film carrier, dissolving the water-soluble film carrier in water, separating the film carrier from a colored layer, and performing printing on the colored photovoltaic by using the water-soluble film carrier. The color layer is adsorbed on the appearance surface of the photovoltaic module, the color photovoltaic module is obtained after drying, the photovoltaic module is adsorbed and combined with the color layer in water, a tangible printing plate or a silk screen structure is not needed, and therefore the method can be applied to manufacturing of color photovoltaic modules of any shapes and any curved surfaces, and due to the flowability of water, the color photovoltaic modules can be manufactured. And the color layer can be completely attached to any position of the photovoltaic module, so that the color quality and the printing precision of the color photovoltaic module are ensured.

Description

technical field [0001] The invention belongs to the technical field of color photovoltaic production, and in particular relates to a method for making color photovoltaics by using a water-soluble film and color photovoltaics. Background technique [0002] Photovoltaic power generation is a technology that directly converts light energy into electrical energy by utilizing the photovoltaic effect of the semiconductor interface. It is mainly composed of solar panels (components), controllers and inverters, and the main components are composed of electronic components. After the solar cells are connected in series, they can be packaged and protected to form a large-area solar cell module, and then combined with power controllers and other components to form a photovoltaic power generation device. As far as my country is concerned, it has a vast territory, the northwest and southwest are basically plateau landforms, and the solar energy resources are very sufficient. In many ar...

[0003] For a long time, photovoltaic power generation has been selected and established in the vast wilderness, and at the same time accommodates a large number of photovoltaic modules to complete the conversion and utilization of solar energy, but the consumption of electric energy basically occurs in the city. The process of electric energy storage and transmission There is no doubt that there will be huge waste of electric energy and economic costs, but in fact, our cities also have long hours of sunlight every day. If we can use the solar energy in the city to directly supply power for specific electrical products, it will reduce the huge amount of electricity. power loss and economic expenditure

The surface layer of general photovoltaic modules is black wafers, which cannot meet the requirements for patterns, aesthetics and fine design in buildings, billboards, publicity signs, wall decorations, and public place guidance signs in the city. Therefore, it is necessary to provide a A method for fine color printing of photovoltaic modules while maintaining photovoltaic power generation efficiency

[0004] Generally, UV ink printing or screen printing patterns are used to make color photovoltaics, but if the photovoltaic modules have special shapes or curves, it becomes complicated and unfeasible to directly print patterns. The invention patent with the notification number CN110843324B discloses a photovoltaic panel The screen printing device and printing method thereof, the ink in the ink tank is pumped out through the liquid pump, introduced into the spray pipe through the conduit, and sprayed downward through each nozzle, and the mesh cylinder is set around the periphery of the nozzle, and passed through The third motor drives the screen cylinder to rotate. When the hollow pattern on the surface of the screen cylinder rotates to the bottom, the ink sprayed from the nozzle is sprayed on the photovoltaic panel passing below through the hollow pattern. Photovoltaic panels are printed without fixing the photovoltaic panels, and the pattern on the photovoltaic panels can be printed after the mesh cylinder rotates once. The printing cycle of a single photovoltaic panel is short, and the ink can be directly sprayed onto the On the surface of the photovoltaic panel, the pattern has a high degree of firmness, which solves the problem that the traditional screen printing device needs to fix the photovoltaic panel during printing, and at the same time needs to set a scraper on the photovoltaic panel. The structure is complex, the cost is high, and the work efficiency is low. Using a scraper Scraping evenly, the technical problem of short service life of the pattern

Like most of the current color photovoltaic printing methods, it can only print photovoltaic panels with uniform shape, flat surface, and no special requirements, and it is best used in large-scale production of the same style of photovoltaics, and the cost of personalized printing for small batches is relatively high
