Problems solved by technology

[0003] The existing stereotyped appearance of solar modules cannot meet people's aesthetic requirements for buildings, and 3D and painted solar modules have emerged as the times require
Chinese patent document CN202021149899.0 discloses a three-dimensional planar power generation tile, and Chinese patent document CN201811581408.7 discloses a color photovoltaic module for photovoltaic tiles. The basic ideas of both are different designs on the cover glass. patterns and film layers to achieve the desired aesthetic and optical effects, the limitation of this type of solution is that the cover plate must be glass, and it is difficult to adjust the product once it is formed
[0004] In addition, Chinese patent documents CN201811114810.4 and CN201910256386.5 achieve this effect by introducing packaging materials with different colors and patterns. The products produced by this method have a weak three-dimensional effect, complex film structure, and difficult pattern layers after lamination. control and other disadvantages

Abstract

The invention discloses a solar module which comprises a substrate, a photoelectric conversion layer, a packaging layer and a cover plate which are sequentially arranged. The photoelectric conversion layer is fixed on the substrate, a pattern layer is arranged on the photoelectric conversion layer, the packaging layer fixes the cover plate on the photoelectric conversion layer, and the cover plate is made of a transparent material. According to the solar module provided by the invention, the patterns are formed on the photoelectric conversion layer, and after the photoelectric conversion layer is covered with the light-transmitting cover plate, various pattern effects can be presented so that the implementation means of the pattern layer are greatly enriched, and the patterns are ensured to be clear and controllable; the selection range of the cover plate can be increased, and the application of the cover plate in the lightweight field is expanded; and the module has the characteristics of convenience in implementation, simple structure and low cost, and the electrical and aesthetic effects are greatly superior to those of a traditional product.

Description

technical field [0001] The invention relates to the field of solar cell components, in particular to the field of 3D and painted pattern production on solar power generation film layers. Background technique [0002] Nowadays, with the advancement of science and technology, the high consumption of energy and the improvement of environmental protection awareness, the solar energy industry has achieved tremendous development. From single-polycrystalline, thin-film, biomass power generation, various solar power generation technologies are contending, and the conversion efficiency continues to create new highs. The market The demand has shifted from the initial large-scale ground battle to industrial and commercial roofs and then to household roofs. Solar clean energy is blooming and shining everywhere. [0003] The existing uniform appearance of solar modules cannot meet people's aesthetic requirements for buildings, and 3D and painted solar modules have emerged as the times re...
