Detailed Description

Example 1

Fig. 1 and 2 are schematic diagrams illustrating a layer splitting diagram of a photovoltaic module including a light source in an embodiment of the present invention, and fig. 2 is a schematic diagram illustrating a composition of a photovoltaic module including a light source in an embodiment of the present invention, as illustrated in the diagram, the photovoltaic module 10 including a light source (hereinafter, referred to as "photovoltaic module 10") is manufactured by a dual-glass packaging process, wherein the photovoltaic module 10 includes a front surface and a back surface, the layer from the front surface to the back surface of the photovoltaic module sequentially includes a first glass layer 101, a first plastic film layer 102, a solar cell 103, an LED array 104, a second plastic film layer 105, and a second glass layer 106, the solar cell 103 and the LED array 104 are located on the same layer, and the solar cell 103 and the LED array 104 are alternately arranged in the same layer.

The above-mentioned photovoltaic module with light source contributes to the prior art in that: the solar building component material has the double functions of solar power generation and light source illumination, can be widely applied to building roofs of airports, station waiting machine halls, large supermarkets and the like, can also be applied to places such as entrance hall eave of buildings of various hotels, office buildings and the like, and is a novel solar building component material.

Specifically, the first glass layer in example 1 is made of transparent glass, and a semi-transparent component with a light transmittance of about 30% is formed, so that natural lighting and passive solar heating inside a building are facilitated.

Specifically, the photovoltaic module in embodiment 1 is manufactured based on a dual-glass encapsulation process, and thus the first adhesive film layer and the second adhesive film layer may be adhesive films made of any one of EVA, POE, liquid silicone, PVB, and ionic polymer.

Example 2

In this embodiment, a schematic diagram of a circuit connection of the photovoltaic module in embodiment 1 in practical application is shown, please refer to fig. 3, a junction box 20 may be installed on a side edge of the photovoltaic module 10, a solar cell lead 1031 and an LED array lead 1041 in the photovoltaic module 10 penetrate into the junction box 20 installed on the side edge of the photovoltaic module 10, then the solar cell lead 1031 is connected out through the junction box 20, and the LED array lead 1041 is connected to a power output terminal of the constant current converter 30 and is powered by an external power supply, so as to light the LED array 104.

Specifically, the structure of the junction box can be as shown in fig. 4, the junction box 20 includes a box body 21 having an accommodating space 211, and a plurality of lead slots 23 are spaced along the lateral direction of the dual-glass photovoltaic assembly on a side surface 212 forming the accommodating space 211 between two ends of the box body 21; the junction box 20 further includes one or more steel sheets 24, the steel sheets 24 being disposed outside the side surface 212 and perpendicularly connected to the side surface 212.
