Description
Technical Field
The invention belongs to the field of building materials, and particularly relates to a photovoltaic building material and a preparation method thereof.
Background
At present, new energy sources which can be utilized by people comprise wind energy, solar energy, ocean energy, geothermal energy and the like, production places of the new energy sources are all arranged in suburbs, deserts or oceans with rare smoke and low energy consumption, and the new energy sources are rarely seen in cities with high population density and concentrated energy consumption. On the one hand, the new energy is not distributed in cities in a concentrated manner, such as concentrated areas of wind energy, ocean energy and geothermal energy are not suitable for human inhabitation; on the other hand, the solar energy is caused by incomplete and unreasonable utilization forms of new energy sources, such as solar energy, which is widely distributed, and a large amount of solar energy can be utilized in cities with large population density, but at present, the main combination mode of cities and solar energy, namely photovoltaic Building Integrated (BIPV), adopts photovoltaic components which generally present dark blue, gray and black, have poor color, texture and texture, are difficult to be highly fused with buildings, and cannot meet the aesthetic requirements of the buildings, and the defects limit the wide application of the photovoltaic components in the buildings, thereby limiting the wide application of the solar energy in the cities.
Based on this, the patent application CN200420085961 adopts optical antireflection films with different thicknesses and types, so that the crystalline silicon solar cell presents different colors; in patent application CN201020272089, an optical medium film layer is added between a glass substrate and a transparent conductive film, so that the optical medium film layer, the transparent glass substrate, the transparent conductive film and an amorphous silicon film form a passive filter system capable of selectively reflecting and absorbing solar spectrum. When the incident angle is changed, the color of the glass curtain wall may change, i.e. the color of the glass curtain wall may be different when viewed from the front and the side. In patent application CN201220200568, the color of the EVA or PVB adhesive film is changed to match the color of the building without changing the battery piece.
Although the above mentioned patents can make the photovoltaic module appear colorful and broaden the application range of the photovoltaic module, the texture of the photovoltaic module is similar to that of glass, and the texture are single, and these shortcomings still limit the application of the photovoltaic module in the building field.
