Technical Field

[0001] The utility model relates to the technical field of photovoltaic curtain walls, in particular to a point-type installed photovoltaic curtain wall. Background Art

[0002] Photovoltaic curtain wall is a curtain wall structure that is pasted on glass and embedded between two pieces of glass. It can convert light energy into electrical energy through batteries. It is also called solar photovoltaic curtain wall. Photovoltaic curtain wall uses photovoltaic cells and photovoltaic panel technology to convert sunlight into electrical energy. Its key technology is solar photovoltaic cell technology. Solar photovoltaic cells use the photon energy of sunlight to move electrons in the irradiated electrolyte or semiconductor material, thereby generating voltage.

[0003] Solar energy is an inexhaustible energy source. In order to convert solar energy into usable energy without pollution, photovoltaic curtain wall technology came into being. Photovoltaic curtain wall is a new type of building curtain wall structure that combines traditional curtain wall with photovoltaic effect. In addition to the performance of ordinary curtain wall, the biggest feature of photovoltaic curtain wall is that it can convert light energy into electrical energy. Solar cells use the photon energy of sunlight to make the electrons of the irradiated electrolyte or semiconductor material move, thereby generating voltage.

[0004] The photovoltaic curtain walls currently in use are mostly conventional frame curtain wall systems that rely on curtain wall columns and beams to facilitate the connection of photovoltaic wiring. For architects who want a simpler photovoltaic curtain wall facade, the system connection structure is often too complicated, and the final curtain wall effect does not meet the architectural effect requirements.
