Problems solved by technology

[0004] Although the above-mentioned patents can make photovoltaic modules appear colorful and broaden the application range of photovoltaic modules, the color of the above-mentioned modules is still single, and these photovoltaic modules still use tempered glass as the packaging protection surface layer, and light pollution such as flashes and dizziness caused by mirror reflection still exists.
Therefore, the above-mentioned photovoltaic modules still cannot be used in large quantities in the construction field

Embodiment 1

[0069] A building material for power generation. The base layer of the building material is flexible stainless steel foil with a thickness of 0.2 mm. A photoelectric conversion layer is arranged on it, and electrodes are led out through wires. A building material finish protective layer is arranged on the photoelectric conversion layer.

[0070] The preparation method of the photoelectric conversion layer is as follows:

[0071] Clean the flexible stainless steel foil substrate and put it into the magnetron sputtering machine. In order to prevent elements in the stainless steel from diffusing into the solar cell, a WTi barrier layer with a thickness of 0.5 μm was sputtered first. The working gas is Ar gas, the sputtering pressure is 0.7Pa, and the background vacuum is 2.0×10 -3 Pa, the substrate is not heated during sputtering. The Mo film was prepared by the three-layer process, the sputtering pressure of the first layer was 1.5Pa, the sputtering pressure of the second lay...

Embodiment 2

[0076] A power generation building material, the base of which is glass with a thickness of 2.0 mm, a photoelectric conversion layer is arranged on it, and a wire lead-out electrode is provided. The preparation process of the photoelectric conversion layer is similar to that of Example 1, except that the CIGS film is replaced by the copper zinc tin sulfur selenium film, and the post-treatment process of the CZTSSe film is replaced by selenization and sulfurization. A barrier layer is arranged on the battery layer, the barrier layer is EVA and glass, and the building material finish protection layer is prepared by manual spraying.

[0077] The ratio of raw materials for the building material facing protective layer: in parts by weight, the mother liquor accounts for 186 parts, and the pigment accounts for 5 parts. The mother liquor used includes 45 parts of potassium silicate and 130 parts of filler, which is a mixture of talcum powder, calcium carbonate and kaolin in a weight ...

Embodiment 3

[0080] A building material for power generation, the base of which is ceramic tiles with a thickness of 8.0 mm, a photoelectric conversion layer is arranged on it, and lead-out electrodes are arranged. The photoelectric conversion layer is a CdTe solar cell, and a barrier layer is arranged on the cell layer. The barrier layer is PVB and ETFE, and a building material facing protective layer is prepared on the barrier layer, and its thickness is 5mm.

[0081] Raw material ratio of building material facing protective layer: by weight, the mother liquor accounts for 100 parts, and the pigment accounts for 5 parts. The mother liquor raw material includes base material, filler and auxiliary agent; the base material accounts for 60 parts, the filler accounts for 18 parts, and the auxiliary agent accounts for 3.8 parts. The base material includes fluorocarbon resin; the pigment includes mica, coral, cadmium red, iron blue and organic green; the filler includes wollastonite powder, qua...

Abstract

The invention discloses a power generation building material and a preparation method thereof. The power generation building material comprises a building material facing protection layer, a photoelectric conversion layer, a functional layer and a building material base layer. The building material facing protection layer is arranged on the first surface of the photoelectric conversion layer and is obtained by liquid curing. The preparation method of the power generation building material comprises the following steps: the functional layer is arranged on the building material base layer; the second surface of the photoelectric conversion layer is tightly attached to the functional layer; the building material base layer and the photoelectric conversion layer are bonded through the functional layer; the first surface of the photoelectric conversion layer is coated with a liquid mixed raw material of the building material facing protection layer, and then is cured to obtain the buildingmaterial facing protection layer. The power generation building material has the texture and the quality of the building material and is rich and diverse in representation form. The building style andthe urban landscape are not changed at all. The material has a wide application prospect.

Description

technical field [0001] The invention belongs to the field of photovoltaics, and in particular relates to a power generation building material and a preparation method thereof. Background technique [0002] Wind energy, solar energy, ocean energy, geothermal energy, etc. are new energy sources that can be used by people at present, and their production sites are located in the suburbs, deserts or oceans with sparsely populated and low energy consumption, and in cities with dense population and huge energy consumption. The use of new energy is rarely seen. On the one hand, this is because the distribution of new energy is not concentrated, such as the concentrated distribution area of ​​wind energy, ocean energy, and geothermal energy, which is not suitable for human habitation; Widespread, there is also plenty of solar energy available in densely populated cities. At present, the main way to combine cities and solar energy is Building Integrated Photovoltaics (BIPV), but th...
