Manufacturing process of high-conductivity and high-voltage solar photovoltaic glass panels

Abstract

The invention provides a manufacturing technology of a high-conductivity and high-voltage solar photoelectric glass board. The technology comprises the following steps: firstly, printing conductive paste; forming a glass board with a circuit layer through sintering, fusing and secondary covering to prepare a high-conductivity transparent glass-based circuit board; and finally welding a solar wafer by a reflow soldering technology. The high-conductivity transparent glass-based circuit board prepared by the middle step is high in light transmittance and high in conductivity; a complete circuit comprising the solar wafer and a conducting circuit can efficiently run; the solar wafer is not easily peeled off after being welded; and the finally prepared high-conductivity and high-voltage solar photoelectric glass board also has high light transmittance and can be applied to the scenes, such as an agricultural greenhouse ceiling, of requiring large-area light transmission.

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, the solar photovoltaic glass produced by this traditional process has limited conduction rate due to the bottom plate with electronic circuits. The conductivity of the glass plate 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
