Curved-surface colored and modular prefabricated power generation building material and manufacturing method

Abstract

The invention discloses a curved-surface colored and modular prefabricated power generation building material and a manufacturing method. The power generation building material is formed through assembling of a plurality of single photovoltaic modules; each photovoltaic module comprises an integrated heat preservation layer, a photovoltaic component adheres to the integrated heat preservation layer through quick mounting supports, at least two quick mounting supports are arranged on the edges of the left and right sides of the lower end surface of the photovoltaic component, the quick mountingsupports are longer than the integrated heat preservation layer, the top end of the integrated heat preservation layer is aligned to the top ends of the quick mounting supports, the bottom end of thephotovoltaic component is aligned to the bottom ends of the quick mounting supports, rubber strips perpendicular to the quick mounting supports are fixedly arranged on the top edge of the top end surface of the photovoltaic component, and a battery layer of the photovoltaic component is a bendable flexible crystalline silicon battery. The power generation building material manufactured with the method integrates heat preservation, heat insulation, water prevention, power generation, decoration and mounting structures, and compared with traditional photovoltaic components, the power generationbuilding material is easier to construct and higher in efficiency.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a power generation building material and a manufacturing method. Background technique [0002] Prefabricated buildings can effectively reduce the amount of wet work on the construction site, reduce labor costs, reduce material waste to a certain extent, reduce construction noise, dust pollution, construction waste and sewage discharge, and are conducive to energy saving under the premise of ensuring the quality of operations Environmental protection, so prefabricated buildings are the development trend of the future construction industry. [0003] Photovoltaic power generation is a technology that directly converts light energy into electrical energy by using the photovoltaic effect of the semiconductor interface. As a new concept for the application of new energy photovoltaic power generation, Building Integrated Photovoltaic (BIPV) is to "integrate" photovoltaic prod...

Problems solved by technology

[0004] At present, the standard photovoltaic modules used in the market do not take into account the structure of the building from the design point of view. In actual use, it is found that the traditional modules are not practical due to problems such as fire performance, waterproof structure, indoor moisture resistance, ventilation and heat dissipation, and building insulation. Large-scale application in building integration system

The specific manifestations are as follows: 1) Traditional photovoltaic modules are widely used in buildings, and most of them use flat glass, which will cause large-scale reflections and cause visual pollution; at the same time, due to the structure and physical characteristics of photovoltaic cells, the structural size is fixed, showing a blue color in arrangement and combination Matrix color blocks, single color form, inconsistent with the overall design style of the building, poor decorative effect for the display of urban culture

2) With the diversification of building shape design, there are more and more curved shapes, which requires building materials to be able to change shapes continuously to meet the needs of buildings; however, affected by the fragility of silicon materials in crystalline silicon photovoltaic modules, photovoltaic modules can only Made into a flat plate, it cannot be combined with building materials

3) Traditional photovoltaic modules adopt a composite packaging structure of glass + photovoltaic cells + plastic backplane. The use of plastic backplane makes conventional photovoltaic products only meet the standard of fire protection class c. As a roof or wall enclosure structure alone, there are certain potential safety hazards; therefore, the installation of conventional photovoltaic modules in buildings increases the load on the roof or walls, which has structural hidden dangers and is likely to cause fi
