And the conductive circuit that melts with the surface of the glass substrate after cooling. There is a solar chip with electrodes on both sides between the two glass substrates. The two electrodes of the solar chip pass through the solder layer of the tin layer and the conductive circuit of the two glass substrates respectively. For connection, the edges of the two glass substrates are provided with a sealant; the glass substrates are tempered glass substrates; the surface of the conductive circuit except the pads for welding solar chips is covered with PCB organic solder resist paint. The high-conduction and high-voltage solar photoelectric glass plate of the present invention has the characteristics of high conduction rate and high light transmittance, and has good thermal conductivity in high-power applications, and can be used in scenes that require large-area light transmission, such as the ceiling of agricultural greenhouses. .

Problems solved by technology

[0004] Due to the large current and strong voltage that solar photovoltaic glass needs to withstand, it needs to have a very strong electrical conductivity. However, this traditional solar photovoltaic glass has a limited conduction rate due to its bottom plate with electronic circuits, resulting in the entire solar photovoltaic glass panel. Conductivity is very limited

At the same time, the butt welding process makes the interconnection between the circuits very strong. Only one side is covered with glass, and the solar chip assembly is under pressure on the glass. It is easy to cause short circuit, there is a great safety hazard, it is difficult to pass the 3C safety certification, and the butt welding machine is expensive and inefficient

In addition, traditional solar photovoltaic glass panels are opaque, and their application is very limited
