Building waterproof photovoltaic assembly and preparation method thereof

Abstract

The invention discloses a building waterproof photovoltaic assembly which is formed by combination of a solar cell and waterproof materials, and a preparation method thereof, relating to the technical field of a photovoltaic assembly. The photovoltaic assembly respectively comprises a waterproof roll material, a solar cell layer consisting of a plurality of solar cell units and a surface packaging material from bottom to top. With the adoption of the photovoltaic assembly and the preparation method thereof provided by the invention, the waterproof material is directly used as a backplane material and is packaged with solar cells into the integral building photovoltaic assembly; the photovoltaic assembly can be directly used as a building material to be used on roofs, thus, the power generation and waterproof functions can be played; and moreover, the photovoltaic assembly is simple and convenient in installation, and the backplane material and a double-surface sticky auxiliary material of the original assembly can be saved, thus, the power generation cost can be reduced.

Description

technical field [0001] The invention relates to the technical field of photovoltaic components, in particular to a building waterproof photovoltaic component formed by combining solar cells and waterproof materials and a preparation method thereof. Background technique [0002] Since the beginning of the 21st century, due to the increasingly prominent energy crisis and environmental pollution, various countries have begun to vigorously seek new clean energy. As the most potential new environmentally friendly renewable energy, the application of solar photovoltaic power generation has sprung up all over the world, especially in Europe and Japan, which has received great support and encouragement from the government, and has developed rapidly in recent years. [0003] The combination of photovoltaics and buildings is the best way to utilize solar energy and an effective way to realize intelligent buildings. There are two main ways of combination: direct placement photovoltaic ...

Problems solved by technology

If the hard substrate battery is applied to the building in the BIPV way, the structure of the photovoltaic module and the building structure need to be redesigned to achieve mutual integration, which will not only increase the difficulty of design but also increase the complexity of the photovoltaic system; Lightweight, foldable, not easy to break, etc. It can be directly laid on the roof for easy installation, but because the flexible battery itself does not meet the requirements of waterproof materials, it still needs to be bonded with the roof during installation, that is, the combination method is still BAPV
