[0002] Solar energy is a clean energy source with the advantages of being safe and reliable, not requiring fuel consumption, easy to maintain, and can be combined with buildings. The luminous photovoltaic building component of the present invention is a component that encapsulates solar cells and light-emitting diodes (LED) chips together, with the light-receiving side of the cell facing the direction of sunlight and the light-emitting side of the LED facing the other side; during the day, the solar cell converts light energy into electrical energy and stores it, and at night, it provides energy-saving LED lighting, adhering to the environmental protection concept advocated in the green industrial era. From the perspective of energy consumption, the luminous photovoltaic building component can be self-sufficient and is a zero-consumption green and environmentally friendly electronic device. This component can also be used as an integrated photovoltaic building component, suitable for installation as a sunshade in a courtyard corridor, saving construction costs and circuit transmission losses.
[0003] Therefore, it is of great significance to study the application of PV-LED photovoltaic lighting integrated components in the field of building components. On this basis, a new type of photovoltaic building component system that can emit light is further designed. On the basis of simultaneously considering the requirements of meeting the strength of the building structure and providing power generation and lighting, this paper designs a photovoltaic building component system composed of two pieces of 5.0mm thick glass, a battery cell series group, an LED series group, PVB, a white PET insulation film and other packaging laminates. The results show that the photovoltaic building component that can emit light uses 5mm thick glass and can provide a wind pressure of 5400Pa. The thickness of the entire component is 12mm, and the glass is tempered glass. Through strict mechanical simulation analysis and calculation, its structural strength can fully meet the requirements of building safety specifications. The use of PVB film effectively improves the bonding strength between the glass and the overall impact resistance of the component, and further cuts off the ultraviolet band to extend the service life of the battery. The photovoltaic building component that can emit light is installed on the ring corridor, so the shape of the component is designed to be an isosceles trapezoid, which is convenient for system arrangement and the overall structure is beautiful. Our research will provide more specific and rich design ideas for the photovoltaic building integrated component system. Utility Model Content

The battery cell series group 2 in the PV-LED component generates electricity during the day and is stored in the energy storage module through the control module. The controller controls the energy storage module to supply power to the LED series group 3 in the PV-LED component for lighting at night.
[0022] The number of thick glasses 1 is two, the thickness of the thick glasses 1 is 5 mm, the material of the thick glasses 1 is tempered glass, and the thickness of the PV-LED assembly is 12 mm.

The optimal working point voltage of the PV-LED module is 22V. The power output of the battery cell series group 2 uses a junction box, and the junction box is installed with two bypass diodes. Effectively reduce the harm and loss caused by the hot spot effect. The circuit output of the luminous photovoltaic building component uses a slot-type pocket junction box, which has a length × width × height = 120mm × 8mm × 8mm, which is easy to hide in the keel as the system support structure, suitable for photovoltaic system installation, and maintains the overall beauty.
