Abstract

The invention discloses a colored photovoltaic module and a preparation method thereof. The colored photovoltaic module comprises a front plate glass layer, a power generation glass layer and a back plate glass layer, wherein the two faces of power generation glass of the power generation glass layer are coated with adhesive, a pattern is arranged on front plate glass of the front plate glass layer, the pattern is composed of a plurality of colored glaze color points, the diameter of the colored glaze color points is 10-100 [mu] m, a gap between the adjacent colored glaze color points is 50-200 [mu] m, and the thickness of the front plate glass ranges from 5 mm to 6 mm. The problems that an existing double-glass photovoltaic module is single in color, poor in attractiveness, poor in impact resistance and high in fragment rate are solved.

Description

technical field [0001] The invention relates to a photovoltaic module and a preparation method thereof, in particular to a color photovoltaic module and a preparation method thereof. Background technique [0002] Photovoltaic modules, also known as solar cell modules, are the core part of solar power generation systems and a necessary part of the BIPV (Building Integrated Photovoltaic) field. In the field of BIPV, traditional photovoltaic modules mostly adopt a double-glass structure, that is, a composite layer composed of two pieces of glass and solar cells, and the cells are connected in series and parallel to the lead terminals to form a double-glass photovoltaic module. Due to the demand for power generation of solar cells, the light transmittance of the glass must be high. Generally, ultra-clear tempered glass is used. Therefore, the color of traditional photovoltaic modules presents the color of the solar cells themselves, mainly black, single color, and insufficient a...
