Abstract

The invention discloses a flexible roof photovoltaic tile. The flexible roof photovoltaic tile comprises a flexible roof tile substrate and a photovoltaic decorative layer, wherein the flexible roof tile substrate adheres to the photovoltaic decorative layer through adhesives, a glass fiber reinforced polymer cement mortar sheet serves as the flexible roof tile substrate, is of a layered structure, and comprises an isolation layer, a back glue layer, a lower polymer cement mortar layer, a high-tenacity glass fiber reinforced non-woven fabric base and an upper polymer cement mortar layer in sequence from bottom to top, and the structures of the five layers are combined into a whole in a solidification mode. Sika single-component high-modulus polyurethane sealing adhesives serve as the adhesives. The photovoltaic decorative layer comprises a flexible thin-film battery assembly, a film layer and a coating layer in sequence from bottom to top. The flexible roof photovoltaic tile is a photovoltaic building material which is light in load borne by a roof, safe, reliable, free of heating through fire in the construction process, easy and convenient to construct and low in comprehensive cost, saves energy, protects the environment, and integrates the function of water resistance, the function of fire resistance, the function of decoration and the function of photovoltaic power generation.

Description

technical field [0001] The invention relates to the field of photovoltaic building integration and photovoltaic building materials, in particular to a flexible roof photovoltaic tile with multiple functions such as fire prevention and waterproof, enhanced crack resistance, roof decoration and photovoltaic power generation, and a preparation method thereof. Background technique [0002] Solar photovoltaic power generation will be the main way for human beings to reduce their dependence on traditional energy sources such as fossil fuels in the future, and to use environmentally friendly and sustainable renewable energy. It will maximize the use of buildings to generate electricity, and the development of photovoltaic buildings is the largest market for solar photovoltaic applications. Therefore, breakthroughs in BIPV complete sets of technology and technological innovation have become the key to the successful application of photovoltaics in buildings. Building Integrated Phot...
