Problems solved by technology

[0005] However, the above-mentioned solar tiles have the following defects: 1. Since silicon-based solar cells are easily affected by the environment, generally in the field of photovoltaics, special polymer materials need to be selected for packaging before they can be used outdoors, and the transparent tiles It is difficult to protect the battery by adding an anti-reflective protective film to the conductive film, and it cannot meet the relevant standards of the photovoltaic industry; 2. The above-mentioned surface anti-reflective protective film is a transparent material, so most of the light will directly incident on the surface of the battery , the reflected color will be the color of the battery itself, which is single and cannot form the texture of the building exterior
[0012] 3) When the formed protective layer is thin, the color of the electrode layer will also be exposed, which makes the photovoltaic cell extremely incompatible with the surrounding environment, thereby limiting its use environment
Other organic polymer materials are prone to aging in a long-term outdoor environment, resulting in a decrease in light transmittance and waterproof performance, seriously affecting their power generation efficiency, and even the risk of falling off the building surface, resulting in the exposure of the electrode layer background

Embodiment 1

[0067] A solar cell, the base of which is a flexible stainless steel foil with a thickness of 0.2 mm, on which a power generation electrode layer is arranged, and a wire lead-out electrode is arranged. A protective layer is arranged on the battery layer, and the material of the protective layer is water-based glaze, which includes soluble silicon inorganic metal salt, has a thickness of 0.1mm, and has a marble pattern.

[0068] Its preparation method is as follows:

[0069] 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 0.5 μm WTi barrier layer was first sputtered. 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 ...

[0077] A solar cell, the base of which is a ceramic tile with a thickness of 2.0mm, a battery layer is arranged on it, and a wire lead-out electrode is arranged. The battery layer has a CdTe solar cell structure, and the specific preparation process is as follows: firstly, the cleaned glass substrate is placed in a sputtering apparatus, the working gas is Ar gas, the sputtering pressure is 0.7Pa, and the background vacuum is 1.5×10 -3 Pa, sputtering deposited a layer of sputtered transparent conductive oxide indium tin oxide film on glass. Subsequently, the CdS slurry was coated into a film by screen printing, dried at 90-120°C for 1-3 hours, and then dried in N 2 Sintering under atmosphere for 0.5-2 hours, the sintering temperature is 650-710°C. Then the slurry containing CdTe powder was printed onto CdS and sintered for 1 hour. Finally, carbon electrodes and Ag paste were printed on CdTe as extraction electrodes. A protective layer is arranged on the battery layer, and th...

Description

technical field [0001] The invention belongs to the field of construction, and in particular relates to a solar battery module used in the field of construction and a preparation method thereof. Background technique [0002] With the continuous development of society, human beings' demand for energy is also increasing, while the global fossil fuels are gradually depleted, and environmental pollution is becoming more and more serious. The development of clean and renewable energy has become the consensus of human society. [0003] However, limited by the limitations of existing technologies, solar cells cannot be properly integrated with the building environment where they are installed. On the one hand, the installation of solar cells often changes or adds to the external structure or additional facilities of the original building; on the other hand On the one hand, the installation itself will also affect the artistic value and humanistic beauty of the building itself. ...
