The invention discloses a crystalline silicon photovoltaic module for building integrated photovoltaic, which is characterized by comprising a toughened glass layer (1) at the bottom layer, a strong impact resistance glass combination layer (4) with a multi-layer structure at the top layer and two layers of sealing adhesive films (2) at an intermediate layer, wherein a crystalline silicon cell (3) is clamped between the two layers of sealing adhesive films (2). The crystalline silicon photovoltaic module for the building integrated photovoltaic, provided by the invention, can resist strong mechanical impact such as bullet impact and the like without being penetrated, can keep complete performance and can be applied to buildings of military or civil special units such as anti-riot, anti-bullet and the like.
Description
technical field [0001] The invention relates to a crystalline silicon photovoltaic module for photovoltaic building integration, which belongs to the field of solar photovoltaic technology. Background technique [0002] Among many energy sources, solar photovoltaic power generation is the most technological and promising way of new energy and renewable energy. The solar photovoltaic cell module is a device that converts light energy into electrical energy under sunlight irradiation, which is composed of glass, crystalline silicon cells, wires, wiring devices, and bonding materials. Recently, building-integrated photovoltaic technology, which organically integrates photovoltaic power generation systems and buildings, is being widely used. Compared with the traditional use of solar cells, integrated photovoltaics and buildings have many advantages: for example, integrated photovoltaics and buildings A part of the cost of building materials becomes an integral part of photovol...
