HIGH-CONDUCTIVITY AND HIGH-VOLTAGE SOLAR PHOTOVOLTAIC GLASS PANEL

摘要

A high-conductivity and high-voltage solar photovoltaic glass panel includes two glass substrates. A surface of each of the two glass substrates faces air. A conductive paste, printed on the surface of the glass substrate, is baked, heated, and cooled to form a conductive circuit fused with the surface of the glass substrate. A solar chip with two electrodes, respectively located on both sides of the solar chip, is clamped between the two glass substrates, and the two electrodes of the solar chip are respectively connected with two solder pads of the two conductive circuits of the two glass substrates through two tin layers. A sealant is placed between the edges of the two glass substrates. The glass substrate is a glass-tempered substrate, and a surface of the conductive circuit, except a region reserved for a solder pad used for welding the solar chip, is covered with a printed-circuit-board (PCB) organic solder-resistant layer. The high-conductivity and high-voltage solar photovoltaic glass panel has the characteristics of high-conductivity and high light transmittance and has the characteristic of good thermal conductivity in high-power applications. The high-conductivity and high-voltage solar photovoltaic glass panel can he applied to the use of large-area light transmission, such as t the agricultural shed roofs.
