The invention provides a high-conductivity and high-voltage solar photoelectric glass plate. The high-conductivity and high-voltage solar photoelectric glass plate comprises two glass substrates; a conductive circuit that conductive slurry printed on the air surface of the glass substrate is fused with the surface of the glass substrate after being baked, heated and cooled is arranged on the surface of each glass substrate; a solar wafer, the electrodes of which are positioned on the two surfaces, is clamped between the two glass substrates; the two electrodes of the solar wafer are connected with bonding pads of the conductive circuits of the two glass substrates through a tin layer respectively; the edges of the two glass substrates are each provided with sealant; the glass substrates are tempered glass substrates; and a PCB organic solder mask covers the surface of the conductive circuit, except the part of the bonding pad for welding the solar wafer. The high-conductivity and high-voltage solar photoelectric glass plate disclosed by the invention has the characteristics of being high in conductivity and light transmittance; the high-conductivity and high-voltage solar photoelectric glass plate has good heat conductive capability while being applied with high power; and thus, the high-conductivity and high-voltage solar photoelectric glass plate can be used in scenes in need of large-area light transmission, such as agricultural greenhouse ceilings.

[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
